cannot open CSPROJ file RRS feed

  • Question

  • I am using VS 2010.  I installed SP1 for 2010.  I installed MCV 3 and now 4.  Installed Nuget.  I am now trying to open a .sln file but receive the error "...it's project type (csproj and cdproj) is not support by version of the application".  I don't really know what was to have helped VS open this file. Is it the mvc 3 installation?

  • Hi,

    To resolve this issue, you need to open the failed .csproj file outside of VS and check what value is assigned to <ProjectTypeGuids> for that project, then refer to this article to identify what type of project is or any extra extension required to add to VS to open those kind of projects.

    Note: I'm not quite sure about .cdproj file and what it could be related to in VS.
