This is the error each time I want to "View in Browser", or run debugging from Visual Studio 2012. Can anyone read out the problem in this stacktrace?
By the way, I have tried to view the site in Page Inspector, the result I get says that no mapping data was returned from the server.

The error itself repeats itself for any project i start in VS2012.
Working on windows 7 64 bit!

Just hit me, I did have some minor fault while installing vs2012. What happened is that during the installation a small time error popped out saying that some component, tool or something named like visual studio 2010 toolkit or something similar can not be found. Some file like vs...04 was missing. Skipped it, install finished and everything seemed to be ok.

Re-started the installation to found out which was the file that was causing the problem. It was vstor40_x64.msi (Visual Studio 2010 Tools for Office Runtime)!
Does this identify as the problem-cause for the stacktrace when trying to debug/view in browser?

About to reinstall VS2012, downloaded the vstor40_x64.exe from microsoft's site, and installed it, all went well for now.

Reinstall did nothing, same problem. I did notice although that the error page states at the bottom:
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929
That is for all I know .NET 4! I checked the property page in VS12 and it is set to 4.5. Help me out here :)...
