Visual Studio 2014 CTP4 and Windows 10 Preview (Build 9860)

Perhaps I am pushing the boundary here, perhaps not but I am having lots of issues with Visual Studio 2014 CTP 4 (specifically Version 14.0.22129.01.DP) and Windows 10 Preview Build 9860.

There have been a lot of errors, and finally it has gotten to the point where even the basic thing like creating a new Console Project results in the following error. I did do a in-place upgrade of Windows from the previous build, but everything else seems to be working out OK – except just can’t write any code.┬á ­čś»

Visual Studio 2014 CTP 4 Error
VS 2014 CTP 4 Error

I am not sure I should try a repair, or deprecate to Visual Studio 2013.
