SYMPTOMS
When you use Microsoft .NET COM Interop, and COM interfaces are being marshaled, a typical exception that occurs when the code runs might cause the marshaled interface to be prematurely cleaned up. If this occurs, when you try to use the interface later, the .NET runtime throws an ExecutionEngineException error.
