When I try to add a new business object to my project I get the following error in the designer window that opens:

A class that inherits from MicroFour.StrataFrame.Business.BusinessLayer must override the property AreCustomDescriptorsEvaluated. Hide

at MicroFour.StrataFrame.Business.BusinessLayer.get_AreCustomDescriptorsEvaluated() at MicroFour.StrataFrame.Business.BusinessLayer..ctor()

I am getting the same error when I open the sample project in designer mode also.  The error does not cause any compile errors.  And the sample still runs properly.
