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.

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

Hi @s.tang
Which version are you using? Are you using the latest RFA .NET 8.1.0.L1?

And does this exception occur if you run without debugger?
0 -
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.

I got this more useful error after tearing down eventqueuegroup has been called when running without debugger.
[ERROR] Application encounter unhandled exception. Exception: System.NullReferenceException: Object reference not set to an instance of an object.

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

You can initialize the Context as many times as needed, provided that you un-initializes them for each
time that the Context has been initialized.Is the issue resolved after you remove the extra Context.Initialize?

Resolved after removing the redundant intialize. Thanks
