Hello.
I suddenly have a major problem with visual studio 2013.
Target framework for new (or existing projects) displaying only 2.0, 3.0 and 3.5, 4.0 is missing from the dropdown list as a result every project which targets F4.0 fails to load.
I have tried numerous solutions even by totally uninstalling every framework and visual studio and re-installing doesn't work.
I even download and installed express versions of VS 2010, 2012 and 2015RC and the problem occurs in all versions.
I have all frameworks installed, all multi-targeting packs and all updates and service packs (windows and VS)
I reached to a dead end to be honest, is there anything else i can do beside re-installing OS (which is a totally unacceptable solution).
