I'm trying to open a silverlight 4 application solution in Expression Blend 3.
However, Blend says that the solution is not supported.
Is there something I'm missing?
I'm following an example in the book Microsoft Silverlight 4 Business Application Development.
You will need Blend 4 to open projects written for Silverlight 4. The solution and project file formats differ. Blend 4 is currently in RC state, you can download it here.
