I successfully built unity project into visual studio 2012 project. But when I opened the .sln file, I got error .csproj is incompatible with my visual studio. I’m using visual studio ultimate 2012 update 4 which I got from my school.
I have researched the solution from microsoft forum and they recommend to open the vs using devenv /ResetSkipPkgs, but it doesn’t help me. How do I solve this problem?Thank you.
What exactly does the error message say? It’s possible that you have multiple versions/copies of Visual Studio and it’s trying to open the solution in the wrong version (e.g. opening a phone project in Visual Studio Express for Windows).
If you have the Express version(s) they may be overriding the VS Ultimate version if you’re opening by double-clicking the .sln file.
Try open the solution (.sln) from within Visual Studio.
Also, I don’t know if the Unity betas allow this, but if you’ve created a WP8.1 game it won’t open in Visual Studio 2012 because it would need 2013.
