title: Xamarin Studio Windows: Cannot open Xamarin Forms files
body: <p>I installed Xamarin Studio on Windows and created a Xamarin Forms project. When I try to open any file in Xamarin Studio, I get the following error.</p>
  
  <blockquote>
    <p>" File could not be opened. Method 'Getlanguageitem' in type
    'Monodevelop.SourceEditor.SourceEditorView' from assembly
    'Monodevelop.SourceEditor, Version=2.6.0.0, Culture=neutral,
    PublicKeyToken=null' doesn't have an implementation.  "</p>
  </blockquote>
  
  <p>I tried to restore NuGet Packages and reinstalled the Xamarin Studio but still get the same error.</p>
  
  <p>How can I solve it? Can you use Xamarin Studio in Windows?</p>
