Cannot Add Connection in VS2010 (Window Closes)

[Richard Cohen]

I've found reports of this bug in many versions of the Connector NET and VS, with no working solutions anywhere. I just installed 6.6.4. I did a complete install and there were no errors. When I go to add a new connection in VS2010, I do Choose Data Source -> MySQL Database and I get to the Add Connection window. If I start to type anything into the window, the window closes immediately without an error. If I press the spacebar in this window, I get "Error: Object reference not set to instance of an object." If I just hit the ok button without typing anything I get "Unable to find the requested .NET Framework Data Provider. It May not be installed."

I verified that all of the mysql DLLs are in Window\Assembly. I've tried uninstalling/installing Connector NET. I've tried uninstalling/installing VS2010. I've tried clearing the AppData\Roaming\VisualStudio folder as others have recommended. I've tried clearing the eventviewer log as others have recommended.

Any help would be appreciated. Thank you.
