Hi,
Thank you for submitting feedback on Visual Studio and .NET Framework. In order to efficiently investigate and reproduce this issue, we are requesting additional information outlined below.

Could you please give us dump of this issue so that we can conduct further research?

Visual Studio now has an extension called Visual Studio 11 Feedback Tool , available on the VS gallery(http://visualstudiogallery.msdn.microsoft.com/f8a5aac8-0418-4f88-9d34-bdbe2c4cfe72).

The extension allows you to
1.    upload files,
2.    collect trace and dump files
3.    collect steps while you're repro'ing the issue, as well as
4.    SQM logs about VS extensions installed
5.    System details (in DxDiag output)

We look forward to hearing from you with this information.
