Stuart,

>I am trying to call my business objects from a vanilla dll. In my tests everything works fine, but when I try calling the function that uses the business objects from VFP I get the error below. I assume I am not pulling in the all the MM classes into the main solution, but I have set references.

You should instantiate an instance of your application object before instantiating and using instances of your business objects---much the same as you do when instantiating them from Visual Studio's Object Test Bench. So, in VFP you could instantiate an instance of AAppTest first, then instantiate an instance of your business object.
