Try this,
1. Open Visual Studio and load your project.
2. Open a second Visual studio and attach the debugger to
the first devenv.exe.
3. Now start debugging your project. Magic! the problem
seems to go away but eventually, after several debugging
sessions devenv.exe will hang in a new way but at least
you can debug.
