Just trying to generate POCO objects, context etc for an existing database by using the EF Power Tools Beta 2 \"Reverse Engineer Code First\" facility.
I\'m using VS2012
i also hit this same problem. The culprit was a package called Entity Framework Power Tool Beta 3. Updated this and everything was back to normal.
This is a legitimate issue on the EF Power Tools, but it's not related to the CTP issue, which was resolved in the final VS Update release. A fix for the EF Power Tools is in the works.

Looks like it is a confirmed issue with Entity framework and Visual Studio 2012 update 1
