Hey Rock,

I don't think you can do that. AFAIK, you can only cast to an interface and that interface must be available to both the caller and callee's AppDomain...

In the past my workaround for those kind of things has been to either implement a specific interface to cast to for any dynamically created types (I was using CodeDom for this) or alternately providing a generic interface to dynamically call methods/properties on the new types through Reflection. The latter has more overhead but the advantage is that it's truly generic and you don't need anything else on the type implementation.

The latter part is written up in my Dynamic Code execution article (about COdeDom) at:

Hope this helps,
