title: How to check which version of Xamarin was used to create the project
body: <p>I keep getting <code>Could not find type 'System.Globalization.SortVersion'</code> exception.
  This seems to be a bug in Xamarin.The workaround is to disable msbuild -- > which produces a theming error (OR) to use the same version of xamarin studio.
  So how can i check which version of Xamarin Studio was used to create the project?</p>
