Daniel Cazzulino has a good article on the subject, http://www.clariusconsulting.net/blogs/kzu/archive/2009/02/19/Makingextensionmethodsamenabletomocking.aspx I think if you applied similar logic you would end up with code like IEnumerable foos = new List(); foos.Finders().FindBy(id); Regards, Paul Hi,
