Commented Task: Make sure VS integration works correctly with EF vNext [1150]

Various things make use of EF in VS--for example MVC scaffolding, the EF designer, etc. These may expect exactly EF6 to be used, when in fact it may be that the version of EF after EF6 is being used. We should do some testing to ensure that these scenarios work correctly before it is too late. This can be done by building EF6 with different assembly information so that it looks like a newer version.
Comments: I made a custom build of EF and gave it version 7.0.0.0, and made sure that this could be installed on MVC4 and MVC5 latest nightly.
