After Mini Spa this year I was fortunate enough to get to chat to Nat Pryce in the bar. He mentioned some interesting projects he’s working on, such as something I think he called “Domainatrix” – a tool you can use to analyse your code to see if it is relevant to the domain. Very nice chap.
Having used NMock (which he helped write) extensively I asked him if anyone was looking after it as there hasn’t been any visible activity for a while. It turns out that Thoughtworks took it over as of release 2.0 but have clearly decided not to support it anymore.
If you’re still using it I highly recommend you start looking for a new mocking tool ASAP.

Clarification:
NMock is not developed further (including its version 2.0).
But NMock2 (https://sourceforge.net/projects/nmock2/) is still under development and has brought some nice new features this year (2008). Yes, yes I know about the bad naming
Therefore, if you used NMock and liked it then please have a look at https://sourceforge.net/projects/nmock2/.
Cheers,
