I get the above error whenever loading any project. If I create a new project, Visual Studio doesnt even work at all, it doesnt attach to the project it doesnt create Slns. Whenever I want to debug and set a break point it just comes up with that error.
I think it may have something to do with standard assets that I used with one project some old post processing assets that dont work with the new Unity(I cant even delete them). But it seems to have broken Visual Studio completely.
