Andrus,

I don't know if this will work, because like Tim, I'm not 100% sure I understand what you're trying to do. But, as far as passing a delegate to a method, you're only missing the correct anonymous delegate syntax. Try this:

new Customer().DoBusinessLogicAndShowResultFormsUsingFormManager(delegate(){FormManager.FormCreator<>});

I'm not sure if you need the type as well, so you might need to do it like this;

new Customer().DoBusinessLogicAndShowResultFormsUsingFormManager(delegate(){FormManager.FormCreator<TEntity>});
