FIX: The debugger receives an invalid handle exception error message when you run AppVerifier on a program that was built on the .NET Framework 1.0

This article has been archived. It is offered "as is" and will no longer be updated.
When you run Application Verifier (AppVerifier) on a program that was built by using the Microsoft .NET Framework 1.0, AppVerifier sends an error message to the debugger, if you have attached a debugger.
This problem occurs because the .NET Framework causes a c0000008 exception error. A c0000008 exception error occurs when a thread tries to close a handle that is not valid or that the thread is not permitted to close.
