Some specifics of my model:

All entities inherit from BusinessEntity (which inherits from Entity). BusinessEntity implements IBusinessEntity. Key field is defined on IBusinessEntity (of type long). [HierarchyRoot(InheritanceSchema.ConcreteTable)] is applied on BusinessEntity.

I am querying for type IMyInterface, and IMyInterface inherits from IBusinessEntity. There are also other interfaces that implement/inherit IMyInterface
