Biztalk: ‘FaultMessageType’: cannot resolve imported ‘messagetype’
When you get the “cannot resolve imported ‘messagetype'” error in Biztalk, it means that you are missing a reference.
In my case
I hada Biztalk project referencing a Framework project which references “Microsoft.Practices.ESB.ExceptionHandling.Schemas.Faults” assembly. I had to add a reference to that assembly in my project as well.
