Please use this discussion to ask your questions to Microsoft experts. We are regularly monitoring this discussion to answer all of your questions.

[IRobot1]

Does the client have to be .NET? Can it be Typescript (app running in the browser)?

[aycabas]

For this hackathon, we accept projects with .NET SDK only.

[IRobot1]

That's too bad. Any reason for this exclusion? I thought the focus was on using the Graph API.

[aycabas]

@waldekmastykarz @daisychaussee

[waldekmastykarz]

This time around we focus on .NET. We'll have more opportunities in the future around other tech stacks.

[kelcho-spense]

@IRobot1 I also joined and started the hackathon thinking I would use React to consume Graph APi, but within few days I have learnt basics about blazor and created a simple project. Hack is sweat when you learn new things 😎😎.

[akirataguchi115]

Is the digital badge going to be a Holopin or something else?

[aycabas]

@daisychaussee @waldekmastykarz

[waldekmastykarz]

We issue digital badges using Credly. These are similar badges to those you get when completing a Microsoft certification.

[Bennett-JA]

Will the sessions be recorded and availible to watch after? I have a conflict so will not make the first session.

[aycabas]

Hi @Bennett-JA, yes, all the sessions will be recorded and on-demand links will be attached in the main Readme page in this repo 😊

Hi, I signed up but I didn't receive any confirmation email. How can I be sure I'm subscribed ?

[BenardMacoutMatur]

Hi, I'm short 2 days of the application process, I just applied today. Can I still participate in this forum? I am a Data Science Student and I am fascinated by learning more and improving my skills.

@aycabas Hi, I'm short 2 days of the application process, I just applied today. Can I still participate in this forum? I am a Data Science Student and I am fascinated by learning more and improving my skills.

[cloudhal]

Yes it's odd, I applied twice because I wasn't sure I completed the sign up the first time. A confirmation email would have been a good idea.

[waldekmastykarz]

You can still join the hackathon @BenardMacoutMatur.

A confirmation email would have been a good idea.

Totally! Sorry we missed that.

[PabloVenino]

Hey, I need to cancel my subscription, and add a friend to do the hacking with me.
How could I do that? Just re-subscribing?

[suntsu42]

I'd like to use my personal Office 365 account ([email protected])
I can easily use this personal account on the Graph Explorer Website, but i did not find an example howto create a proper GraphServiceClient instance in c#.
What do i have to use as ClientID/TenentID when i want to use my personal account?

[waldekmastykarz]

To create a new application, in Azure Active Directory go to App registrations:

Then, use New registration to register a new app:

Just to be clear: I do have a personal, paid microsoft account with which i get outlook/word/onedrive and so on.

Got it. When you said "personal account" with an @outlook.com email, I thought you referred to a "Microsoft account". But there are paid licenses that offer you access to Office 365 without custom domain. I assume you've got that one, right? Either way: you should be able to create a new app in Azure Active Directory and connect to Microsoft Graph.

[suntsu42]

Thanks for the help

Quick feedback:
With my personal account, i wasn't unable to get it running. Problem is that my personal account is somehow attached to the azure tenant of my company and i don't have permission to create new app registrations. But thats my problem.

I then created a very new account on outlook.com, and created an application registration. With this i get the following error.
I can't add the user since with such a free account, i cannot edit the Enterprise Application (Seems to be a limitation of a free personal account)

I now use the demo account i've created as part of this hackaton with which i am able to access the grap api.

[svrooij]

@suntsu42 Send me a message at my email (which you can find on my github profile) and I'll help you out with a client ID from my developer tenant.

[suntsu42]

@svrooij it's already working. I've created a demo account as part of this hackaton. This then gave me a properly working azure instance.
but thanks for the offer

[sergiokml]

@suntsu42 Hola! I'm late, but the answer is no because free personal accounts don't work for this purpose.

[SomebodyToLove1337]

Hello,

sorry im a complete noob at coding. But i realy like to learn it, im an sysadmin since 20 years but only used to PowerShell and Batch at the Moment.
So i started after the kick-off with the realy good tutorial for .NET with Microsoft Graph.
I´m at step 4 now, but my program didn´t run anymore:
https://learn.microsoft.com/en-us/graph/tutorials/dotnet?tabs=aad&tutorial-step=4

I followed the tutorial, but i got an error in my Visual Studio Code... I didn´t found what i´m doing wrong... Maybe someone can give me an tipp :)

Thats my error message (Sorry just got it in German :( ):
Der Typ- oder Namespacename "User" wurde nicht gefunden (möglicherweise fehlt eine using-Direktive oder ein Assemblyverweis). [GraphTutorial]csharp(CS0246)

and

"MeRequestBuilder" enthält keine Definition für "Request", und es konnte keine zugängliche Request-Erweiterungsmethode gefunden werden, die ein erstes Argument vom Typ "MeRequestBuilder" akzeptiert (möglicherweise fehlt eine using-Direktive oder ein Assemblyverweis).

Here is my Code:

using Azure.Core;
using Azure.Identity;
using Microsoft.Graph;

class GraphHelper
{
    // Settings object
private static Settings? _settings;
// User auth token credential
private static DeviceCodeCredential? _deviceCodeCredential;
// Client configured with user authentication
private static GraphServiceClient? _userClient;

public static void InitializeGraphForUserAuth(Settings settings,
    Func<DeviceCodeInfo, CancellationToken, Task> deviceCodePrompt)
{
    _settings = settings;

    _deviceCodeCredential = new DeviceCodeCredential(deviceCodePrompt,
        settings.TenantId, settings.ClientId);

    _userClient = new GraphServiceClient(_deviceCodeCredential, settings.GraphUserScopes);
}
public static async Task<string> GetUserTokenAsync()
{
    // Ensure credential isn't null
    _ = _deviceCodeCredential ??
        throw new System.NullReferenceException("Graph has not been initialized for user auth");

    // Ensure scopes isn't null
    _ = _settings?.GraphUserScopes ?? throw new System.ArgumentNullException("Argument 'scopes' cannot be null");

    // Request token with given scopes
    var context = new TokenRequestContext(_settings.GraphUserScopes);
    var response = await _deviceCodeCredential.GetTokenAsync(context);
    return response.Token;
}
public static Task<User> GetUserAsync()
{
    // Ensure client isn't null
    _ = _userClient ??
        throw new System.NullReferenceException("Graph has not been initialized for user auth");

    return _userClient.Me
        .Request()
        .Select(u => new
        {
            // Only request specific properties
            u.DisplayName,
            u.Mail,
            u.UserPrincipalName
        })
        .GetAsync();
}
}

Love if anyone can help me :)

Br,
Somebody

[aycabas]

Hi, let me try to help you! Can you try to add using Microsoft.Graph.User; on top of your code. Seems like you are getting an error about User namespace.

You may find the details in step 4, under the Strongly-typed return type title: https://learn.microsoft.com/en-us/graph/tutorials/dotnet?tabs=aad&tutorial-step=4

Let me know if it works.

[leethengwei]

I am having the same issue. Installing the default latest Microsoft.Graph V5.0.0 library will encounter this issue. I have to manually downgrade the version to V4.54.0 in the Nuget Package Manager for it to work.

[cloudhal]

Yes as far as I can see almost all the tutorials relate to 4 and not 5. There's so many breaking changes in 5 personally I'm avoiding it for now until the documentation is more complete.

[SomebodyToLove1337]

Hello,

thank you for your answers.
Unfortunately I didn't have the time to work on my project the last days.
Today I would like to get a little further. Now I know at least what the problem is.
I will now use the templates from Hackathron. These should be in the latest version.

Thanks a lot for your help and I hope I can finish my first project in C# :)

[waldekmastykarz]

There are indeed a few breaking changes between Microsoft Graph .NET SDK v4 and v5. We've updated the console app, .NET MAUI and UWP templates to use the v5 of the SDK. For Blazor and MVC apps, for now you'll need to use the v4 of SDK which is coming from the Microsoft.Identity.Web.MicrosoftGraph interop.

[anish1617]

Hello, can we use .NET Core API and ReactJS for the project. And also, i have registered for the program with project teams undecided and i have a colleague who is interested to work with me, on that regard do i have to resubmit the form for registration. Do i need to mention my team member anywhere?

[aycabas]

Hi @anish1617, welcome to the hack! As long as you use Microsoft Graph .NET SDK in your project, we can accept your submissions. You may find some templates to get started in the repo.

Each participant should register separately to Hack Together, if you registered already, you don't have to register again. If your colleague registers as well, and you both work on a project together, make sure to mention your colleague's github account when you are submitting your project. This way, we'll know that you worked as a team 😊

[alexanderjanjic]

Hey amazing MS Graph Team!

I have two questions:

• Can we also submit solutions that are related to Azure B2C configuration using Graph SDK?
• Can we use the beta API which has extended functionality?

[waldekmastykarz]

Hey @alexanderjanjic! Yes, to both your questions: it's perfectly fine to use Azure AD B2C and you can use beta endpoints. As long as your hack is built using .NET and you use the Microsoft Graph .NET SDK, you're good to go 💪

[Lawe02]

Hi, my name is Lawe Zangena and i am currently studying a 2 year .NET Framework course in Sweden. I am learning about the graph api on my own but have not been able to use it because if i use my school account i need the admin permission and i can not use my personal account.
What should i do?

[svrooij]

Hi @Lawe02 send me and email at the address on my github profile and I'll try to help you out with credentials from my dev tenant.

[svrooij]

or you can create a free developer tenant over here: https://developer.microsoft.com/en-us/microsoft-365/dev-program for free.

[Lawe02]

Thanks a lot, I will be in touch.

[phuctran22071992]

Can you guy create a free developer tenant from sandbox 365?

[waldekmastykarz]

@phuctran22071992 yes, the instant sandbox you get through the Microsoft 365 Developer Proxy is a free tenant for development purposes.

[KamilSiebyla]

Hi all,

I have a question regarding calling graph for calendar events :-) Here you have some details:

I am trying to build proper request like this:

    try
    {
        var eventPage = await graphClient.Me.CalendarView
        .Request(viewOptions)
        .Select(e => new
        {
            e.Subject,
            e.Organizer
        })
        .OrderBy("start/dateTime")
        .GetAsync();

        events = eventPage.CurrentPage;
    }
    catch (Exception ex)
    {
        throw new Exception($"Error when fetching events: {ex.Message}");
    }

Code from above failing due to "Resource could not be discovered" . Moreover, I am able to make exactly the same call from GraphExplorer and it is working. I have checked my scopes, permissions for app registration - everything seems to be in place.

Also, I have found information, that I need licence to O365 to make such calls from Graph. Could you confirm/decline this?

When it comes to fetching user related data it is working from the code perfectly.

I would be glad for any input here, because I am blocked a little with my project due to this issue :-)

Thanks in advance :-)

/Kamil

[svrooij]

Yes, to access the calendar you need an Office 365 calendar (and you only get one of you have a license).

But you can create a developer tenant over here: https://developer.microsoft.com/en-us/microsoft-365/dev-program for free.

[KamilSiebyla]

Thanks for the information :-)

[OzBob]

I would like some guideance on querying SharePoint #52

How to list a Subfolders and documents in a Sharepoint Documents 'folder' or is it site/drive or site/list? In Sharepoint web view it looks like this:

Drive Items is null or empty

 var _d = await graphClient
                        .Drives[driveid]
                        .GetAsync();
                        //.GetAsync(requestConfiguration => {
                        //requestConfiguration.QueryParameters.Expand = new string[] { "items" };});//throws oData error
                        //requestConfiguration.QueryParameters.Expand = new string[] { "children" };});//throws oData error

Also, apologies if I'm not git'ing correctly, I'm happy to take advice on fork/pr/ ettiquette and best practices.

[OzBob]

MSGraph SDK v5 upgrade docs "List children from a site's drive" example, doesn't expand on how to get all the "itemId".

[waldekmastykarz]

You can get the information by calling https://graph.microsoft.com/v1.0/drives/{drive-id}/root/children. That gives you the list of files and folder in the top level of a document library. From there, you'll get information about items and their IDs which will allow you to iterate through the list.

[OzBob]

that was a bit helpful.

To get the {drive-id} you refer to for a non-root sharepoint site:

Using f12 tools on the website: https://{yoursubdomain}.sharepoint.com/_layouts/15/sharepoint.aspx?v=sites
gave me the response from: /_api/v2.1/insights/recentSites?%24top=21
To get the {drive-id}
<-needs the 'drives' response
<-needs the sharepoint site-id
<-needs the MSGraph dotnetsdk 'sites' response (note: the graph explorer does not return any results but the MSGraph dotnet does!)
<-which has a 'siteid', but it is a multipart id, (undocumented)
in the format: $"{siteCollection.hostName},{sharepointIds.siteId},{sharepointIds.webId}"

Having worked this out I feel a need to update some MSLearn/MSGraph documentation - any suggestions?

[OzBob]

The MSGraph dotnet SDK for drives does not reflect the MSGraph explorer:

var _siteDrive= await graphClient
    .Drives[siteDriveid]
    .GetAsync(requestConfiguration => {
        //requestConfiguration.QueryParameters.Expand = new string[] { "items" };});//throws oData error
        //requestConfiguration.QueryParameters.Expand = new string[] { "children" };});//throws oData error
    });

var dItems = _siteDrive?.Items; // is null always.

var _siteDriveItems = await graphClient
    .Drives[siteDriveid]
    .Items
    .GetAsync();// throws The 'filter' query option must be provided.

[shadev256]

Is anyone interested in teaming up with me.

[phuctran22071992]

Can anyone register an 365 sandbox account ? I can't created this time

[KamilSiebyla]

Hi,

where exactly you have problem with this? Maybe I will be able to give you a hand :)

/Kamil

[waldekmastykarz]

@phuctran22071992 did you get any errors that you could share so that we can help you troubleshoot?

[phuctran22071992]

Hi @waldekmastykarz @KamilSiebyla
here is my issue. I'm also try other way, but I can't get the verification code when trying to register

[phuctran22071992]

Sometimes, the popup was shown for enter the information for register. But when I enter my phone, I can't get any verification code

I created a functioning Blazor app, logging the user in and retrieving info from Graph, and then upgraded the Microsoft.Graph package from 4.54 to 5.0, because I saw it was released.
Everything broke, now I see there are breaking changes, but it's unfortunate timing that this was released in the middle of the hackathon.
So I know have a load more work to do in order to fix everything, or should I just stay on 4.54? I can' see much documentation about 5.0, so do you suggest upgrading or sticking on 4.54 for now?

[cloudhal]

specifially I used this document https://learn.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/graph-api?view=aspnetcore-7.0&pivots=graph-sdk to create a Blazor WASM app using the Graph SDK, however it does not work for the 5.0 release.

[waldekmastykarz]

Would you mind sharing what issues you ran into? There are some breaking changes between Microsoft Graph .NET SDK v4 and v5, so it's absolutely possible that the code won't work as-is and will need to be adjusted.

[cloudhal]

Yes, just add the class file GraphClientExtensions.cs, it's a mess of errors after v5 installed, works fine with 4.54. So obviously written for 4. Basically all the blazor docs are out of date now that v5 has been released, see dotnet/AspNetCore.Docs#28001 you can see how much they've got to do.

[ghost]

Hi. Can everyone register without belonging to an organisation or school?

[jkher]

Hello,

I have been playing around LinkedResources for TodoTaskItem. I need to filter todo items which contains LinkedResources with specific ExternalId. I am unable to move forward with the filter.

https://graph.microsoft.com/v1.0/me/todo/lists/{todo_list_id}/tasks?$filter=linkedResources/any(resource:resource/externalId eq '{resource_external_id}')

In Microsoft graph explorer, I encounter this error and same goes with my application. I'd appreciate if someone can get me past this issue. Thanks.

{
"error": {
"code": "invalidRequest",
"message": "CollectionNavigationNode operation is not supported in query filters.",
"innerError": {
"date": "2023-03-06T16:04:40",
"request-id": ".......",
"client-request-id": "......."
}
}
}

[aycabas]

Hi @jkher, to get linkedResources, can you please try the following query: GET /me/todo/lists/{todoTaskListId}/tasks/{taskId}/linkedResources/{linkedResourcesId}.

Here is the official documentation for getting linkedResources from To-do: https://learn.microsoft.com/en-us/graph/api/linkedresource-get?view=graph-rest-1.0&tabs=http

[jkher]

Thanks @aycabas, I don't have task Id to use. I have externalId of the resource and I need to do a reverse search using lambda expression. Get all todos which has reference to external ID in linked resources.

Since this really did not work for me, I had to introduce EFCore as a work-around for now. I am storing these relationships between external resource ID and todo ID in a sqlite table.

[aycabas]

@jkher, by getting all the tasks in your list with the following query will also bring you linkedResources, you won't actually need the TaskId, you'll only need todoTaskListId when you use the following query:
GET /me/todo/lists/{todoTaskListId}/tasks

Please take a look at this example and let me know if this helps :https://learn.microsoft.com/en-us/graph/api/todotasklist-list-tasks?view=graph-rest-1.0&tabs=http#request

[KamilSiebyla]

Hi all,

got some small issue. I need to make a call to graph and get events from particular user like this:

` try
{
var eventPage = await graphClient
.Users[coworker.Id]
.CalendarView
.Request(viewOptions)
.Select(e => new
{
e.Subject,
e.Organizer,
e.Attendees,
e.Start,
e.End
})
.OrderBy("start/dateTime")
.GetAsync();

            coworker.CalendarView = eventPage;
        }
        catch (Exception ex)
        {
            throw new Exception($"Error when fetching events: {ex.Message}");
        }`

I am not sure if I am going with proper scopes: "MailboxSettings.Read;Calendars.ReadWrite" - it seems, that something like this is not exactly enough and I am not able to find valuable information's, so I am asking: Could you give me some advice here? Will be grateful :)

/Kamil

[aycabas]

Happy to help! If you are trying to get a list of calendar events through Microsoft Graph, you'll need the following scopes: Calendars.Read, Calendars.ReadWrite. You'll need to make a GET request to the following endpoint: GET /users/{id | userPrincipalName}/calendar/events.

Here is an example code snippet with Microsoft Graph .NET SDK: var graphClient = new GraphServiceClient(requestAdapter);

var result = await graphClient.Me.Calendar.Events.GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Filter = "startsWith(subject,'All')";
});

Here is the documentation for getting calendar events and let us know if you still need help: https://learn.microsoft.com/en-us/graph/api/calendar-list-events?view=graph-rest-1.0

[KamilSiebyla]

Hi,

it is better after some adjustments, but still I have some problems:

| ex.Message | 'Code: ErrorItemNotFound\nMessage: The specified object was not found in the store.\nInner error:\n\tAdditionalData:\n\tdate: 2023-03-07T15:39:57\n\trequest-id: 4ec18a7e-9acb-4df9-b583-5b41695d95fe\n\tclient-request-id: 4ec18a7e-9acb-4df9-b583-5b41695d95fe\nClientRequestId: 4ec18a7e-9acb-4df9-b583-5b41695d95fe\n' | string

This person got some event scheduled. I have checked also licenses and permissions - everything is in right place imo.

I am just trying to fetch all events for particular user like that:

var events = await graphClient .Users[coworker.Id] .Calendar .Events .Request() .GetAsync();

Thanks for any further information's in advance :)

/Kamil

[aycabas]

Hi @KamilSiebyla, can you let me know what kind of you are using to create graphClient?

[KamilSiebyla]

Hi @aycabas ,

sure :) I am using just client factory to provide client to my services (by DI) eg. MessagesService, PresenceService etc. etc. :

`namespace MHT.Infrastructure.Factories
{
public class GraphClientFactory
{
private readonly ILogger logger;
private readonly IAccessTokenProviderAccessor accessor;
private readonly HttpClient httpClient;

    private GraphServiceClient? graphClient;

    public GraphClientFactory(
        IAccessTokenProviderAccessor accessor,
        HttpClient httpClient,
        ILogger<GraphClientFactory> logger)
    {
        this.accessor = accessor;
        this.httpClient = httpClient;
        this.logger = logger;
    }

    public GraphServiceClient GetAuthenticatedClient()
    {
        graphClient ??= new GraphServiceClient(httpClient)
        {
            AuthenticationProvider =
                new AuthenticationProvider(accessor)
        };

        return graphClient;
    }
}

}`

In addition - every other case is working perfectly fine. I am fetching for example current logged-in user events for whole week:
`public async Task<IList?> GetCurrentUserCalendarForNextWeekAsync(string graphTimeZone, List viewOptions)
{
if (_graphClient == null) return null;

        try
        {
            var eventPage = await _graphClient
                .Me
                .CalendarView
                .Request(viewOptions)
                .Header("Prefer", $"outlook.timezone=\"{graphTimeZone}\"")
                .Top(50)
                .Select(e => new
                {
                    e.Subject,
                    e.Organizer,
                    e.Attendees,
                    e.Start,
                    e.End
                })
                .OrderBy("start/dateTime")
                .GetAsync();

            return eventPage.CurrentPage;
        }
        catch (Exception ex)
        {
            throw new Exception($"Error when fetching events: {ex.Message}");
        }

    }`

and it is working like a charm :) Only calls for other user's events (based on userId) is not working. I think it could be something related with configuration on my tenant.

If you will be able to help with this, it would be nice - if there will be more problems, I will use some dummy data, because I am using a lot of code related with GRAPH in my project. But it would be small waste :)

Thanks in advance :)

/Kamil

[aycabas]

Hi @KamilSiebyla I just realized I couldn't type authentication in my previous message 😅 I tried to ask earlier what kind of authentication/permissions you are using to create Graph client? If you use delegated permissions, you need user consent to access other user's data.I suggest you to check out app-only authentication that requires admin consent, by using app-only permissions you can access any user's data in your tenant as long as you have admin consent: https://learn.microsoft.com/en-us/powershell/microsoftgraph/app-only?view=graph-powershell-1.0&tabs=azure-portal

@aycabas any ideas?

Hi @Vedshruti-11, you may try to remove the Microsoft identity platform connected service and add again. Let us know if the issue continues.

[tajbender]

Hi,

thanks for the great event @waldekmastykarz ! 🎉

However, I have a problem regarding my Azure Build pipeline. Perhaps someone can help?

https://github.com/electrifier/electrifier/actions/runs/4353232316

Never used this before. I get the message:
Analyze (csharp)
We were unable to automatically build your code. Please replace the call to the autobuild action with your custom build steps. Failure invoking /opt/hostedtoolcache/CodeQL/2.12.2-20230207/x64/codeql/csharp/tools/autobuild.sh with arguments

Any ideas? Thx in advance.

[waldekmastykarz]

Hey @tajbender, I haven't used this GitHub Action in the past, so don't know what's wrong exactly, but let me ask around.

[andrueastman]

Hey @tajbender,

Please check out the workflow file here on how you can build your code as a sample. Sometimes the CodeQL task cannot automatically build a project for analysis so you would need to add a task for dotnet build and then let CodeQL just do the analysis.

https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/fd6f353ca49bd262d18bc91736ec16bbc293f354/.github/workflows/validatePullRequest.yml#L21

[tajbender]

thanks, @andrueastman,

I'll check that. Thanks in advance for your help. I'm sure it's just a tiny setting, cause local build runs fine without any problems.

However, this is currently not critical, as I'm aware that for the contest the thing hasn't ro be published to the store.

Thanks, Regards,
tajbender

Hello @aycabas & @waldekmastykarz
Hope you are doing great !
I registered for the Hack Together event with my personal account, but I didn't receive a confirmation email on the same. Could you please confirm the same.

[waldekmastykarz]

We've got your registration! Sorry for the confusion. Looking forward to seeing your hack!

Thank you for the confirmation

[SomebodyToLove1337]

Hello,

I have a problem again and hope that someone can help me.
In the meantime my small console application runs quite well and I wanted to access the mailbox settings via graph. In graph explorer I managed to do it (even if it doesn't suggest the option automatically):
https://graph.microsoft.com/v1.0/me/mailboxSettings

However, in my application I always get the error (csharp(CS1061)) when I want to access "MailboxSettings".
var o365CalRequest2 = await graphClient.Me.mailboxSettings.GetAsync((requestConfiguration)

It seems to me that the command is simply not available, but I have no idea how to add it.
My scope should be correct: MailboxSettings.Read

I'm a complete beginner unfortunately, so it would be super nice if you could explain your answer a bit :)

Thanks in advance

Br,
Somebody

[SomebodyToLove1337]

ah sorry.
I have also tried to query the graph on /me and then call the data via the variable.
With Variable.MailboxSettings but the value is unfortunately always NULL.

var o365CalRequest = await graphClient.Me.Calendar.Events.GetAsync((requestConfiguration);
Console.WriteLine(o365CalRequest2.MailboxSettings);

[StevanFreeborn]

@SomebodyToLove1337 here is what I came up with for retrieving mailbox settings for users:

https://gist.github.com/StevanFreeborn/b5b5824b320b7932e5e10616ecc5edcd

The same approach doesn't appear to work using graphClient.Me.

Here is the microsoft docs on the topic:

https://learn.microsoft.com/en-us/graph/api/user-get-mailboxsettings?view=graph-rest-1.0&tabs=http

It doesn't look like getting this information is baked into the sdk because there isn't a snippet for it on that page and I couldn't find anything looking through the sdk itself.

Although I'm far from an expert so happy for one of the microsoft team members to correct me.

[andrueastman]

Hey @SomebodyToLove1337
MailboxSettings is a structural property of the User type so to access it you would use a select query as below.

var o365CalRequest = await graphServiceClient.Me.GetAsync(requestConfiguration => 
    {
        requestConfiguration.QueryParameters.Select = new string[] { "mailboxSettings" };
    }
);
var mailboxSettings = o365CalRequest?.MailboxSettings;

[StevanFreeborn]

That is the approach I used for the getting it for all users. I think it didn't work for me on the me endpoint because I was using an app-only set of permissions. 🤦🏻‍♂️.

[SomebodyToLove1337]

Hello,

oh yeeees, it works. I´m so happy now, it takes hours but now i understand my failure, thank you so mutch guys.

@andrueastman
this was exactly the part my brain didn´t want to understand. But now i got it.

I can´t thank you all enough <3

[xueapp]

Hello all, I ran into the "missing odata.nextLink" error when using GraphServiceHelper.SendEmail, can't seem to get around it. I'm using graph lib 4.2 from the template, is it an issue with this specific version? I'm new to .NET and graph library, I tried to manually upgrade to v5.0.0 in csproj file, but it keeps restoring back. Could you please help point me to the right direction?

[xueapp]

private async void handleSendEmail()
  {   
    var user = await GraphServiceClient.Me.Request().GetAsync();
    @* Recipient currentUserRecipient = "@(new Recipient())"; *@
    Recipient currentUserRecipient = new Recipient();
    EmailAddress currentUserEmailAdress = new EmailAddress();
        currentUserEmailAdress.Address = user.Mail;
        currentUserEmailAdress.Name = user.DisplayName;
        currentUserRecipient.EmailAddress = currentUserEmailAdress;

    try{
        ItemBody messageBody = new ItemBody();
        messageBody.Content = "this is the test email body";
        messageBody.ContentType = BodyType.Text;

        Message newMessage = new Message();
        newMessage.Subject = "\ntest message subject.";
        newMessage.ToRecipients = new List<Recipient> { currentUserRecipient };
        newMessage.Body = messageBody;

    {
      Console.WriteLine($"Error sending email: {ex.Message}");
      throw;
    }
  }

[waldekmastykarz]

Thanks for reaching out @xueapp. In which place exactly are you getting this error? Is it being caused by PostAsync() and then captured in the catch clause?

[xueapp]

I believe so, and I attached the error message

[blackhawk64]

Hello!

I'm having a problem with this:

var response = await _graphServiceClient.Teams[$"{_teamId}"].Members.Request().GetAsync();

I'm trying to get de UserId. When I make a debbug, the information inside response show the expected value, but the problem is when I do this:

foreach (var item in response)
{
var member = item.UserId;
}

It says that ConversationMember doen't has a definition for UserId. So I was wondering were is the problem, am I doing something wrong or I need to perform an additional process?

[waldekmastykarz]

Interesting. I can see the userId property in the API just fine. @andrueastman any idea what could be wrong?

[andrueastman]

Hey @blackhawk64,

The API returns a collection of the base class ConversationMember which doesn't contain the property. This is because the conversation members could be any of the derived instances like AnonymousGuestConversationMember (an external guest) or AadUserConversationMember (a user who is a member of the tenant).

You would therefore need to check the type first and then access the property with something like below.

            var response = await graphServiceClient.Teams[$""].Members.Request().GetAsync();

            foreach(var conversationMember in response)
            {
                if (conversationMember is AadUserConversationMember aadUser)
                {
                    var userID = aadUser.UserId;
                }
            }

https://learn.microsoft.com/en-us/graph/api/team-list-members?view=graph-rest-1.0&tabs=http#response

[blackhawk64]

Awesome! I tried it and seems like it's working fine. Thanks a lot! @andrueastman

[SomebodyToLove1337]

Hiho,

sorry again me.
Now I have developed some things in my console app. But when I want to write the data back to office365 I always get the following error:

Exception has occurred: CLR/Microsoft.Graph.Models.ODataErrors.ODataError
An exception of type 'Microsoft.Graph.Models.ODataErrors.ODataError' occurred in dotnet-console-microsoft-graph.dll but was not handled in user code
   at Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.<ThrowIfFailedResponse>d__28.MoveNext()

   at Microsoft.Graph.Users.Item.UserItemRequestBuilder.<PatchAsync>d__149.MoveNext()
   at Program.<<Main>$>d__0.MoveNext() in C:\GitHub\hackTheCalendar\Program.cs:line 119

But the permissions should be ok. But I just can't execute a patch command on "mailboxSettings":

This should be the relevant code:

    startDTTZ.DateTime = start.ToString();
    startDTTZ.TimeZone = timezone;
    endDTTZ.DateTime = end.ToString();
    endDTTZ.TimeZone = timezone;

        var patchUser = new User
        {
            MailboxSettings = new MailboxSettings
            {
                AutomaticRepliesSetting = new AutomaticRepliesSetting
                {
                    ScheduledStartDateTime = startDTTZ,
                    ScheduledEndDateTime = endDTTZ
                }
            }
        };
    await graphClient.Users[$"{o365UserID}"].PatchAsync(patchUser);

Can anyone tell me what could be the problem here?

Thanks a lot

[MartinM85]

According to the doc the correct endpoint to update mailbox settings is

PATCH /users/{id|userPrincipalName}/mailboxSettings

but SDK doesn't have any related MailboxSettings builder.

await graphClient.Users[$"{o365UserID}"].MailboxSettings

I guess it's a bug in SDK.

Any way you can use try-catch and check the exception in debugger

try
{
    await graphClient.Users[$"{o365UserID}"].PatchAsync(patchUser);
}
catch (Exception ex)
{
}

[SomebodyToLove1337]

hmm.. okay thanks.
Do you know how i can fix this? I tried an API Call with Postman and there i can update my autoreply settings.

Is there any way to update it with a manuell API Call like in postman? How can i do this in C#?

Thanks in advance.

Br,
Somebody

[MartinM85]

It would be useful to share details of the exception.

[andrueastman]

Hi @SomebodyToLove1337,

Unfortunately, structural properties that can be accessed through the URI are not accessible through the SDK at the moment. You can however workaround this by using the request builders as below.

            var mailboxSettings = new MailboxSettings
            {
                AutomaticRepliesSetting = new AutomaticRepliesSetting
                {
                    ScheduledStartDateTime = new DateTimeTimeZone(),
                    ScheduledEndDateTime = new DateTimeTimeZone()
                }
            };
            var requestInformation = graphServiceClient.Users["{o365UserID}"].ToGetRequestInformation();
            requestInformation.HttpMethod = Method.PATCH;
            requestInformation.UrlTemplate = "{+baseurl}/users/{user%2Did}/mailboxSettings";//update the template to include /mailBoxSettings
            requestInformation.SetContentFromParsable<MailboxSettings>(graphServiceClient.RequestAdapter, "application/json", mailboxSettings);

            await graphServiceClient.RequestAdapter.SendNoContentAsync(requestInformation);

[SomebodyToLove1337]

Hi @andrueastman ,

thank you so mutch. That code runs like a charm. You realy saved my project!!! Im looking forward to implement a config file and beautify my code. And then i can send it in :)
First Console App in C#, im soooo happy!!!

@MartinM85
Thanks you, too. I tried to get the execption over the weekend, but unfortunately he still ran into the ODATA error. Although I, as written by you, had packed the code in a try / catch.

thank you so mutch for your support :)

Could you help me, please?

Sorry for the code example, I don't know how to make this work. I hope it's clear enough.

Hi Emre, can you please try this one and let me know:

var graphClient = new GraphServiceClient(requestAdapter);
var requestBody = new Microsoft.Graph.Me.SendMail.SendMailPostRequestBody
{
	Message = new Message
	{
		Subject = "Test mail",
		Body = new ItemBody

			ContentType = BodyType.Text,
			Content = "Test mail content",
		},
		ToRecipients = new List<Recipient>
		{
			new Recipient
			{
				EmailAddress = new EmailAddress
				{
					Address = "[email protected]",
				},
			},
		},
		CcRecipients = new List<Recipient>
		{
			new Recipient
			{
				EmailAddress = new EmailAddress
				{
					Address = "[email protected]",
				},
			},
		},
	},
	SaveToSentItems = false,
};
await graphClient.Me.SendMail.PostAsync(requestBody);

Hello,

Thank you. I've checked the graph api explorer but the version used in the explorer might be old. And the version in the Blazor template is also quite old but not the same as the version used in the explorer. I've updated the version to the latest version. The same code I have provided in my comment works now.

 <PackageReference Include="Microsoft.Identity.Web" Version="1.16.0" />
 <PackageReference Include="Microsoft.Identity.Web.MicrosoftGraph" Version="1.16.0" />

Hi!

My project is almost I still have to manage the timezones only.
My project is a client app (WinUI, Android) & an API and also there is the Graph API too.
The question is what is the best practice to detect the user timezone from the client and send it to the server and then use it in the Graph requests?
Is there a recommended way or just use the mailboxSettings?

Thanks!

[waldekmastykarz]

Yes, time zone is stored on mailboxSettings, so if you want to align with user's time zone, best get it from there. https://learn.microsoft.com/graph/api/resources/mailboxsettings?view=graph-rest-1.0

[tajbender]

Hello @waldekmastykarz @aycabas,

I ran into trouble again. For some days now, I can't debug my solution, albeit being in debug mode.

Any ideas, any help?

Thanks in advance,
tajbender

[tajbender]

Repository: https://github.com/electrifier/electrifier

[waldekmastykarz]

Have you tried cleaning and rebuilding your project? If you look back at commits/changes to your repo, can you see what's change and revert back to a state where you can attach the debugger?

[tajbender]

Yes, multiple times.
Every then and when it works fine, and then Visual Studio gets screwed totally 😿

I've de-installed the Visual Studio beta some days ago, maybe the machine got messed 🔥 🧨

I'll keep hacking 🍭

[tajbender]

...work in progress. Thx @waldekmastykarz

Hi. I have a teams toolkit .net tab app. I will like to add bot functionality to my existing app. Due to using .NET, I am not sure how to do it. I know with VSCode there is the cool teams toolkit extension where you can click a button and add new features.. doesnt seem to translate over to .NET. Will appreciate any assistance. Much needed. Thank you.

[aksoftware98]

No I mean you can create them in .NET and because Graph is your API so your app will be good.
You can directly create a bot fully setup using the Teams Toolkit for .NET
Not sure if I got what you mean exactly

[kerisha]

I created a TeamsFx Toolkit tab app for .NET from the template. (works well)
I want to click a button in that Tab app and trigger a bot to send myself a notification. I want to do this from the tab, essentially, I want to add bot functionality to the Tab app.

The above image is what I did to create the tab app.
Now, I want to add bot functionality to this Tab app that I have created.

[kerisha]

Hope that helps

[aksoftware98]

Yeah, you can build the bot as a separate project because it needs to be hosted separately and you will HTTP endpoint.
So you create the bot and host it.
Then from your tab project you can call the BOT endpoint to send a message

[kerisha]

Thanks.
Seeing how easy it is in VSCode with the toolkit extension made me want that functionality on .NET
Wished it was there. But cool, thanks!
