Debugging a Visual Studio 2010 extension or addin, always gives me LoaderLock

I'm trying to write an extension for VS2010, but I get this every time:

1. Hit F5 to start debugging
2. A new instance of visual studio starts up
3. I can see a bunch of DLLs loading in the debug host while the new instance i开发者_JAVA百科s starting
4. It then fails with a "LoaderLock".

When I continue after that, the new instance is fully functional, but there's no debugging happening at all.

The same happens when creating an addin.

Any clues?

You should disable LoadLockException doing the following :

• Click Debug/Exception...
• Extend Manage debugging assistant
• Uncheck LoaderLock in the list

The exception should not be thrown anymore when debbugging.
