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
