Wpf – Visual Studio 2012 : Remote Debugging Monitor (MSVSMON.EXE) does not appear to be running on the remote computer


I've Visual Studio 2012 Ultimate on Windows 7 x64 machine.
Today when I tried to run my WPF application I got this error :
enter image description here

What's wrong ? What is remote debugging ? I just want to run my application.

I've also lunched "msvsmon.exe" but it didn't fix my problem.

Restarting my machine was another way to get rid of this problem that I tried.

How do I fix it?

Best Solution

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!
