Switching to VisualStudio 2008 to 2012 FrameWork3.5sp1 to 4.0 or 4.5

I'm trying to get my Addin to run in solidworks with my new software  I got it to compile and it show up in the addin list but it will not run or stop on a debug pause

I'm pausing on the first line under the ConnectToSw

This is a solution with 9 project in it and I have 5 of the  project can be ran within the addin or as stand-a-lone and they work fine in stand-a-lone

is there somthing that need to be change to work
