title: mvvm-light : losing intellisense on VS2012
body: <p>We are using MVVM Light Toolkit (from Galasoft - Laurent Bugnion).
  Until now we were using Visual Studio 2010.
  Everything was working well (thanks to Laurent).</p>
  
  <p>Two days ago we moved to Visual Studio 2012.
  And now Intellisense is no longer working in Xaml files (but still working in code-behind).</p>
  
  <p>After looking on forums and made some tests, it appears that we have an issue with "GalaSoft.MvvmLight.Extras.SL5.dll".</p>
  
  <p>As soon as GalaSoft.MvvmLight.Extras.SL5.dll is removed from project references, intellisense is working again.</p>
  
  <p>Someone already had same problem and/or know a solution ?</p>
  
  <p>Thanks.</p>
  
  <p>Alain.</p>
