title: .csproj file is missing while checkin the pending changes in TFS
body: <p>I am working in Visual Studio 2010 with Team Foundation Server 2010. Everything was fine with the check in and check out. Now I am stuck with a problem. The problem is <code>.csproj</code> file is missing while showing the pending changes. Because of this when I check in any <code>.cs</code> file it is not updated in server. Can anyone say me in what way I am going wrong?</p>
