Introduced a new embedded resource, `ResourceDictionary.windows.xaml`, in the `CommunityToolkit.Maui.MediaElement.csproj` project file. Updated `MauiMediaElement.windows.cs`: - Imported new namespaces. - Added `CustomTransportControls` field and methods for loading resource dictionary and applying custom styles. - Updated constructor to load resource dictionary and set custom transport controls. - Added `LoadResourceDictionary`, `ApplyCustomStyle`, and `SetTransportControls` methods. - Updated `Dispose` method to handle custom transport controls. - Removed `OnMediaPlayerElementPointerMoved` method and related code. - Updated `OnFullScreenButtonClick` method to remove fullscreen button references. Updated `MediaManager.windows.cs`: - Disabled `SystemMediaTransportControls` in `CreatePlatformView`. Added `CustomTransportControls` class in `CommunityToolkit.Maui.Primitives`: - Imported necessary namespaces. - Defined `FullScreenButton` property. - Implemented `OnTemplateLoaded` event. - Overrode `OnApplyTemplate` method to add full-screen button. - Added `FullScreenButton_Click` event handler. - Introduced `isFullScreen` field to track full-screen state.
Moved RightSeparator before PlaybackRateButton in ResourceDictionary.windows.xaml. Added RightSeparator with Height='0', Width='0', and Margin='0,0'. Reordered properties of PlaybackRateButton without changing values. Removed original RightSeparator after PlaybackRateButton.
Re-added various properties and elements to styles and templates in `ResourceDictionary.windows.xaml` to ensure consistent UI appearance and behavior. Added new buttons like `ZoomButton` and `CastButton` to the media controls command bar. Enhanced `customTransportcontrols` and `CommandBarStyle` with additional properties.
Removed the `UseLayoutRounding` property and adjusted the `Margin` property from `0,0,0,20` to `0,0,0,10`. Added `VerticalContentAlignment` set to `Center` and `VerticalAlignment` set to `Bottom`. Introduced `CornerRadius` of `8,8,8,8` to the `Grid` element in the `ResourceDictionary.windows.xaml` file.
- Cleaned up `using` directives by removing redundant `using CommunityToolkit.Maui.Core;` and reordering the remaining directives. - Changed `CustomTransportControls` class from public sealed to sealed partial. - Removed XML documentation comments for `CustomTransportControls` class and its members. - Changed `FullScreenButton` property from nullable `AppBarButton` with a private setter to non-nullable `AppBarButton` initialized with a new instance. - Removed null check for `FullScreenButton` in `FullScreenButton_Click` method as `FullScreenButton` is no longer nullable.

- The variable name FullScreenButton should be renamed to fullScreenButton to follow the naming conventions.
public AppBarButton FullScreenButton = new();

- The
LoadResourceDictionarymethod does not handle the case where the resource dictionary might not load correctly, which could lead to a runtime error. Add a null check forresourceDictionary.
var resourceDictionary = (Microsoft.UI.Xaml.ResourceDictionary)XamlReader.Load(xaml);

- The
OnFullScreenButtonClickmethod does not check ifCurrentPageis null before using it, which could lead to aNullReferenceException. Add a null check forCurrentPage.
