Loader lock error

Question

I am building on C++ dll, by writing code in C#.

I get an error, saying

LoaderLock was detected Message: Attempting managed execution insid

Answer 1

I recently got this error while creating an instance of an COM-Object written in native code:

m_ComObject = Activator.CreateInstance(Type.GetTypeFromProgID("Fancy.McDancy"));

This led to the described error. A "LoaderLock was detected"-Exception was thrown.

I overcame this error by creating the object-instance in an extra thread:

ThreadStart threadRef = new ThreadStart(delegate { m_ComObject = Activator.CreateInstance(Type.GetTypeFromProgID("Fancy.McDancy")); });
Thread myThread = new Thread(threadRef);

myThread.Start();
myThread.Join(); // for synchronization
