WF4 RC - Cannot create unknown type when loading WF Service from loose Xaml with ActivityXamlServices

Question

I am trying to host a WF4 (RC) Service dynamically. I have a test solution with two projects. The first is a declarative workflow service library with one root Flowchart act

Short answer - Xaml load can't infer the local (default) assembly, so you need to specify it on XamlReaderSettings.LocalAssembly.
