title: Intellisense not working for XAML in VS2012 and only partially in Blend
body: <p>I'm trying to get RC of Visual Studio 2012 working for XAML files. I can't seem to get any XAML Intellisense and the option within Tools is greyed out.</p>
  
  <p>I've also tried to run the solution using Blend, however I only get Intellisense for custom controls such as telerik then.</p>

  <p>When ever I drag controls onto the design surface I get an "Object reference not set to an instance of an object" exception but the control is still added to the surface.</p>
  
  <p>I've read that this was a bug within VS11 and was fixed with in the Visual Studio 2012 RC.</p>
  
  <p>I've created a new Silverlight Application and the intellisense is working so i'm wondering if its an issue with how my projects are set up.</p>
  
  <p>I have all of my Styles within a separate themes project, which is referenced by other all other projects. Within the designer these references show up as errors but when the application runs they are resolved fine.</p>
  
  <p>Would unresolved resources at design time affect Intellisense?</p>
