Windows 7 x64, VS 2012

In my case, the Remote Debugging Monitor component was installed and the app was clearly configured to debug locally in settings. This was a WinForms app upgraded from VS 2008, .NET 3.5.

Turns out it was the Windows Firewall. By directly running:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe

A firewall dialog appeared where I could allow msvsmon.exe to run. After a VS 2012 re-start, debugging (locally) was fine!
