title: Xamarin Studio Monogame.Framework.dll Reference Error
body: <p>When I create a brand new iOS Monogame project the references Lidgren.Network and MonoGame.Framework can't be found.  So I delete them and then in edit references I go to Library/Application Support/XamarinStudio-4.0/LocalInstall/Addins/MonoDevelop.Monogame.3.0.1 and attempt to select Monogame.Framework.dll and Lindgren.Network.dll and get the following error:</p>
  
  <pre><code>System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---&gt; System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.
  </code></pre>
  
  <p>It seems like a "file not found" error but the files are obviously there because I can select them in the folder?  Does anyone have any advice?  Am I overlooking something easy?</p>
