title: Visual Studio 2010 - .Sln file when clicking on .csproj
body: <p>I can open my project by double clicking on the .csproj file. It opens fine and it doesn’t generate a .sln. If I copy the same project to a virtual machine and do the same it opens but creates a .sln file.</p>
  
  <p>I really don’t need a solution I would prefer to only work on a single project.</p>
  
  <p>Am I missing something here?</p>
