System.ComponentModel.AsyncOperation.VerifyNotCompleted error in Marketplace Error Report

Question

I have got System.ComponentModel.AsyncOperation.VerifyNotCompleted as an error in my stacktrace report from the marketplace for windows phone. I am using background worker to do work in the background thread. This error is occurring more in windows phone 8 than in windows phone 7.

Please can anyone explain this error?

Answer 1

The only solution that helped me in this case was preventing access to background worker by two threads at the same time. I would suggest others to do the same and prevent simultaneous access to the worker by to threads.
