I have a problem adding ADO.Net Entity Data Model to my existing project, or even while opening a project which contains *.edmx files.(In my case ) Visual Studio closes automatically. I see the following error in the event log every time this happens
Googled the specific error but drew a blank.

.NET Runtime version 2.0.50727.4016 - Fatal Execution Engine Error (70207A3E) (80131506)

I run Visual Studio Team System 2008 with SP1 on Windows Vista Enterprise

I also have Power Commands set up. Wondering if that could be a possible source of the problem?

Help on this issue would be appreciated.

Thanks in Advance

    uninstalled VS2008 and installed it again. Am now able to work with all kinds of solutions, projects and files. Have yet to pin point if it was any particular add-on that I had installed.
