Using DefaultAzureCredential in iot-service-client 2.0.2

[HarryAcker]

When creating the message client to send C2D should the DefaultAzureCredential work for authentication. When I create the MessagingClient it looks like it works, the open method times out 3 or 4 times but then returns OK but a call to isOpen return false. The exact same code works fine with a connection string. If the token was no good I would expect an unauthorized exception when trying to open the client. Anyone tried the DefaultAzureCredential in this scenario? And just to verify in the same code I use DefaultAzureCredential to create a KV secret client and that works 100%.

Do you have a code snippet that demonstrates this issue? I'd be happy to try it out on my end to see what is happening.
