Lot of InvalidOperationExceptions

[zdamir]

Hi, I'm spammed with following exceptions, when running [MongoDB.Driver.Core.Extensions.DiagnosticSources] as a Source in Otel Tracing

System.InvalidOperationException HResult=0x80131509 Message=Trying to set an Activity that is not running Source=System.Diagnostics.DiagnosticSource StackTrace: at System.Diagnostics.Activity.NotifyError(Exception exception) in System.Diagnostics\Activity.cs:line 1146

Here's a stacktrace of issue

Any Idea why is this happening?

I can provide snippets if needed.

Thanks

Hello,

the problem is that DiagnosticsActivityEventSubscriber wants to return previously captured current activity to Activity.Current property again. In the Activity.Current setter there is a check that fails when the activity is stopped.

There is actually one more issue. The same code raises the exception also when you call a sync version of a mongo command. In this case, command's activity is the same as the Activity.Current activity. Inside action(), activity gets stopped, and afterwards activity is again assigned to Activity.Current property.

Both issues are fixed in my PR: #32
