title: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
body: <p>I have been programming a game using C#, Visual Studio and the Monogame Framework. Today i reopened the program after a long time on a new computer and also upgraded the monogame framework.</p>
  
  <p>However, when i try to compile, i get this error:</p>
  
  <blockquote>
    <p>System.IO.FileNotFoundException was unhandled
    Message: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

  <p>Does anyone have any idea how to fix this?</p>
  
  <p>I am absolutely new to anything *.dll-related, so i have no clue where to start searching.</p>
  
  <p>Thanx a lot!</p>
