I would like to have a Base BO from which I inherit a bunch of similar BOs that just have different properties, and attach to different tables in the db.  I would like to have a set of MustOverride type properties, so that I can have sort of a template for the inherited BOs.  I have done this, which causes the Base class to be abstract.  Then,  in the inherited BO, I change the Inherits MicroFour.StrataFrame.Business.BusinessLayer to Inherits BBS.Biz.Base.TableBO in my inherited class (including the partial).  Everything works great except that when I want to pull up the design view for the Inherited BO it gives me this error:

The designer must create an instance of type 'BBS.Biz.Base.TableBO' but it cannot because the type is declared as abstract.

Is there any way to get around this, or is there a better way to accomplish what I'm trying to do here?
