title: What version of Blend supports WPF 4.5, Portable Class Library?
body: <p>I am setting up the project structure for a new greenfield application.  Our initial release will only support a WPF client, but we want to eventually roll out Metro and Silverlight clients as well.  I decided on the following:</p>
  
  <p>Core Library - Portable class library targeting .NET for metro, .NET 4.5, SL4, Windows Phone 7.5</p>
  
  <p>WPF Application - Targeting .NET 4.5</p>
  
  <p>Our Model/ViewModel layer is defined in the Core Library, View defined in the WPF Application.  I chose .NET 4.5 in order to support defining the viewmodel in the core library in a way that can be consumed by both WPF and Metro.</p>
  
  <p>This works fine in the Visual Studio 11 Beta running on Windows 7 Pro.  I have a working view that is data bound to the ViewModel defined in the Core Library.  My problem is Blend.  When I open the View in Blend, I get no designer.  I suspect the problem here is support for WPF on .NET 4.5.  I have tried Blend 4 and Blend for VS11 Beta.  </p>
  
  <p>Does anyone know how to get the designer working in Blend for WPF views as described above?</p>
  
  <p>*Status as of 2012-05-10:
    No combination of VS11 and Blend appear to support WPF 4.5.</p>
