Fwd: "can't convert Subclass_..." when isolating an interface

I just looked at your sample project

It’s best to require spec before caricature because caricature hooks
into
spec
The IHomeRepository interface is empty. Try adding a method to that and
see
if it still occurs.

you can also add require ‘caricature/aspnet_mvc’

I don’t have a windows machine running atm but I’ll check tomorrow if
this
didn’t help you
