Operation taking longer than expected - Visual Studio 2012

One of the long lived issue I struggled with was Visual Studio 2012's  "Operation taking longer than expected", as you can see in the screenshot shown below.

















I tried many opetions including the most frustating one- re-install and repair the Visual Studio 2012.

The major problem of this issue is that it doesn't allow you to do many critical things for example "Attching a process during debugging" etc.

The solution to this problem is:

1. Navigate to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Remote Debugger
2. Open x64 folder and rename the msvsmon.exe file to msvsmon_old.exe
3. Now, navigate to x86 folder and copy msvsmon.exe and paste it into x64 folder.
4. Restart the Visusl Studio 2012 IDE, and now try attching to process during debugging.

Hope this will help.
