Visual Studio 2010 freezes when debugging x64 application

Recently, my coworker and I upgraded our development environment to Win7 x64 with VS2010 Pro. Our application is specifically targeted at x64 platform.

The problem we are encountering is during debugging, when attempting to step through the code (F10), at least 50% of the time VS will simply lock up the application being debugged. The IDE has the appearance of having pressed F5, but the application is not responsive and we have to force stop the application.

Our application is a Client (GUI) and a Server that communicate through .NET remoting.

This is starting to directly affect our productivity, so if anyone has any ideas what may be causing th开发者_Go百科is, please let me know.

There is an outside chance that it might be the debug symbols loading. Check the status bar I think it tells you when the symbols are loading.

This may be a moot point, but have you installed the VS 2010 service pack 1?

There are various bugfixes related to debuggers included.

I had a similar problem. it turned out that a higher level program had a different run-time library (multi-threaded debug dll), while my app was simply a multi-threaded debug. Once I converted mine to a multi-threaded debug dll, the freeze stopped happening.
