Exception thrown after disposing RFA resource

I get the exception thrown (see attached file) when debugging my application in visual studio. It happens when I exit the application. What does it mean?

On dispose, I have invoked deactivate and destroy on eventqueuegroup, destroy ommconsumer, release session and Context.Uninitialized. Each call to cleanup resources doesn't trigger the exception, only during exit the debugger host process.

Hi @s.tang

Which version are you using? Are you using the latest RFA .NET 8.1.0.L1?

yes, on 8.1.0.L1.

EDITED:

The attached log is generated with 8.0.1 version. I downloaded 8.1.0.L1 and has exception thrown as well on exit.

And does this exception occur if you run without debugger?

I got this more useful error after tearing down eventqueuegroup has been called when running without debugger.

[ERROR] Application encounter unhandled exception.

i think it's to do with me mistakenly calling an extra Context.Initialize. I assume that is not good!

Make sure each Context.Initialize is match to Context.Uninitialize while tearing down app
