Visual Studio Pro 2012 crashes with a MissingFieldException immediately after opening a solution

Question

I have downloaded some source code from our TFS and my setup is via VPN. I installed the same VS2012 installer in my machine at home and my machine at the office.

As soon as I open the solution Visual Studio 2012 crashes. I tried uninstalling, running CCleaner, then re-installing but I am still having errors.

The following facts are relevant:

• I have admin rights to this PC
• It does have other versions of Visual Studio installed
• I have the latest Windows 7 and Visual Studio 2012 patches

The following is from the crash report:

Answer 1

The solution for me was to download and apply the first update from the official download page.

I've had the exact same problem with VS 2012 Ultimate.

The problem seems to be that at least the ISO-download of the 3 official downloads comes with the same, outdated version as yours, and I got the exact same exception every time I opened a solution.

Answer 2

Hey renamed the "ComponentModelCache" folder in %localappdata%\microsoft\visualstudio\11.0\

This resolved the issue.
