I tested the 4.2 install with an empty project and all works ok but this custom 4.2 project is not happy for some reason.

Anyone else have experience with this and able to resolve it.

You might find this forum thread on Microsoft Connect useful.

I have a feeling that your problem is related to the entity Framework DLL’s; so try setting your Local Copy to true.

If you can’t find how to do this, edit your csproj file and find <Private>False</Private> line and set to true.
