[NMock2-Dev] Re: mocking interface with generic list property

[Joe R. <joe...@gm...>]

I believe you can disregard this question.  Since sending the email
I've discovered that I can pass a Matcher to the "To" method in
addition to a value.  This seems to accomplish what I'm after.  I was
trying to do .To (value).Matching (myMatcher) which I now know to be
incorrect.

If there's a better way to do this, I'd still like to hear any advice.

Thanks!
