title: no .sln file in c# project
body: <p>I want to open a project in <code>Visual Studio 2012</code> and I am looking at the source folder, but it does not have a solution file. The project looks like a class library project and it has one <code>.csproj</code> file and everything else is <code>.cs</code> files. </p>
  
  <p>I am not sure how to open this project.</p>
  
  <p><em>Any suggestions?</em></p>
