My problem is that in my scenario, I have a project with two parallel project files for different build targets. I have a ProjectName.WP8.csproj and ProjectName.WinRT.csproj, which essentially include the same files.
I am trying to check-in this solution (SolutionName.WinRT.sln) to TFS and I get no errors. All the code changes to the code in the project goes through, but when I check the actual state of TFS, the (newer) PorjectName.WinRT.csproj files are not checked in.
This is quite peculiar since it worked perfectly for the WP8 version. How can I support this kind of scenario?
(If it's not possible, how do I easily migrate my parallel project to another TFS project?)
