[mattjohnsonpint]

Fixes #2065

[christallire]

Could we get this released ASAP? I have too many UnobservedTaskException without stack traces

[mattjohnsonpint]

Yes, there will be a release very soon, probably tomorrow. Thanks for your patience.

@christallire, @dbruning - 3.24.1 has been release which includes this fix. Please update and let us know how it goes. Thanks.

@mattjohnsonpint I am not sure if it's related, but I am using Sentry.AspNetCore 3.29.1 nuget and all the issues I get via UnobservedTaskException mechanism have a very short stack trace:

OpenQA.Selenium.WebDriverException: Cannot start the driver service on http://localhost:61414/
  ?, in void DriverService.Start()
  File "Task.cs", line 2381, in void Task.ExecuteWithThreadLocal(ref Task currentTaskSlot, Thread threadPoolThread)

System.Net.Sockets.SocketException: The I/O operation has been aborted because of either a thread exit or an application request.
  File "Socket.Tasks.cs", line 1451, in void AwaitableSocketAsyncEventArgs.ThrowException(SocketError error, CancellationToken cancellationToken)
  File "ValueTask.cs", line 271, in void ValueTaskSourceAsTask.s_completionAction(object state)

Is there any way to fix this?

@brnbs - That's not related to this.

You appear to have a legitimate unobserved task exception related to Selenium web driver not being able to start the driver service. That particular exception is thrown from here.

As to why it's unobserved, I can't exactly say. At first glance, that doesn't appear to be in called in an async code path within that library. Given the short stack trace, I can only guess that something like Task.Run(() => SomeDriverService.Start()) is being called somewhere else.

At any rate, I don't believe there's any Sentry issue here. Thanks.
