I have a new installation of VS 2012 Premium on Win8 and am trying to open an existing Silverlight project. The project contains a link to System.Windows.Interactivity.dll, which could not be found. VS2012 has built-in Blend, but where is the SDK? Do I need to download it from somewhere? Should I install the trial version of Blend Ultimate that I had on my old VS2010 machine?
