Since upgrading to VS2015 I now have several project errors relating to the Blend SDK
For example:
The type 'EventToCommand' from assembly 'GalaSoft.MvvmLight.Platform' is built with an older version of the Blend SDK, and is not supported in a Windows Presentation Framework 4 project.
The type 'InvokeCommandAction' from assembly 'Microsoft.Practices.Prism.Interactivity' is built with an older version of the Blend SDK, and is not supported in a Windows Presentation Framework 4 project.
I have checked and the project references System.Windows.Interactivity v4.0.30319 (4.5)
