title: How do I add a custom msbuild project to visual studio
body: <p>I want to add a custom MSBuild project file to my solution.  I have looked and there is the ability to add a .msbuildproj to the solution, but everytime I try to do it, it hangs Visual Studio.</p>
  
  <p>What I am trying to do is add a project file that I can run MSBuild tasks as part of the overall solution build process.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I am not looking to extend the existing build process.  I want to add a new project to solution that is not a csharp or cpp project.</p>
