Create a new WPF project in VS and change nothing. The Design View will fail to load with the error below.
Error 1 Could not load type 'Microsoft.Expression.DesignModel.Core.ISharedInstanceBuilder' from assembly 'Microsoft.Expression.DesignModel, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
Microsoft.Expression.DesignModel is an assembly from Expression Blend.
I ever installed Blend 4 RC and uninstall and install Blend 4. I Reflector the assembly I have under Blend 4 bin folder. And cannot find a interface named ISharedInstanceBuilder.
But the WPF project is a Template project without any changes. How it get related with Blend 4? And how to fix it? Thanks.
