I'm working on a binding prototype for a new project and ran into a snag with Blend and binding. We're trying to us a BindableEntity class with the ICustomTypeDescriptor interface implemented. The reason for this is to allow a separation between Entity Framework and binding on the UI.
The problem we've run into is Blend using reflection instead of the ICustomTypeDescriptor implementation for our property descriptors. For example, when I click on the binding for one of the text blocks in the Main Window I need the FirstName and LastName properties to show up so the designer can select them. I don't want them to use a custom binding. Ironically, Visual Studio demonstrates the desired behavior.
Here is a link to the Source Code
Does anyone have any ideas on how to accomplish this?
