How to override the code generation for Generate > Class in VS 2010

Question

I have read http://stackoverflow.com/questions/913836/why-are-my-classes-private-by-default-in-visual-studio and succcessfully used the advice given. Now if I invoke Add > New Item, > Class (or just Add > Class), I get the empty class created the way I want it (as a Public class, amongst other things).

However, if within my code I write the name of a non-existent class and then I right-click on it and invoke Generate > Class then the code that this generates is the old default code for a class - without my modifications. In other words, it appears that Generate > Class does not use the Class.zip template that is used when you do Add > New Item, > Class (or just Add > Class).

Can anyone tell me where the template (or other mechanism) for the code generated by Generate > Class is located?

Thanks.
