MQTT Channel is Closed / Migrating Sample to .net8 caused an issue

[codeputer]

See attached screen shot of the repo that I'm using.

i did have some stable code, running for at least 8 months, in which I was using DPS (ProvisioningClient) to provision an IOT device. when I upgraded to .Net8, my testing revealed an error.

I got this sample working as is (.net6) , but used my DPS and IOT service credentials. Then I upgraded the transport and the provisioning client to current versions, and .Net8, and got the following error without any other changes made to the repo.

I then downgraded to versions in this repo (not sure which NUGET, as I ran out of time) the error disappeared!

Following is a more detailed shot the call stack and error generated - it takes at least 40 seconds or so before it fails.

I'm on production issue, and I'm now rolling back to get this working.

Using the sample project from the repo, I made two changes. changed the project to .Net8, and updated the Microsoft.Azure.Devices.Client library from 1.41.2 to 1.42.2 - and it broke the RegisterAsync() method - MQTT Socket Closed after about 40 seconds. Change it back to 1.41.2, and it worked

Need help on this one as its a production issue for me - will try to work around by downgrading my application.

This is likely a dup of #3413. The latest dotnetty library has some compatibility issues with .NET 8 that we are aware of and are working on

Closing as dup

Oh good...that took three days out of my life. Client not happy with the instability. R Get Outlook for Android<https://aka.ms/AAb9ysg>
