Unfortunately NUnit 1.0 was a bit of a balls up (it was a direct port 
line for line
of JUnit which didn't make the most of .NET). So lots of other people 
started writing alternatives that were better. Then NUnit 2.0 came out 
(recently) which kind of won, but there are still lots of people use 
other tools.

Agree. Any ideas? I was thinking about making an abstraction over the 
other apis, but compared with writing a very simple class it just didnt 
make sense.

Well, there is the IsNull contstraint. I found I used IsAnything alot 
more than IsNull so I made it a default. However it's obviously 
confusing. Would like to get more people's opinions on this...

Yup. It's on the todo list:
