VS2010 Debug entry very slow

Question

When I start debugging my web application either from Start with Debugging (F5) or attaching to the ASP.NET worker process it will load the assemblies from the application v

Answer 1

Yes, msvsmon.exe will be used when you debug a 64-bit program. Since Visual Studio is completely 32-bit, the remote debugger is needed to bridge the divide.

There isn't any reason to assume that the slowdown is caused by it being a remote debugger. Working mightily to find and load the .pdb files would be likely. Or accidentally having the mixed-mode debugging option turned on so the debugger is also seeing all unmanaged DLL loads and finding symbols for them. These are just guesses of course.
