New Version
As some of you have already noticed, the last version of NUnitAddIn expired today. With impeccable timing my Subversion server ran out of space and 'wedged'. Luckily I do have backups and local versions on various machines. To cut a long story short, I have been recovering that rather than getting out a new version for the last 24 hours.
I have uploaded an interim version here whilst I sort out the repository. You can find the latest version here. Remember to shut down all instances of Visual Studio and uninstall the old version of NUnitAddIn before you install. You can find a quick way to re-install using the command line here.
Expect documentation and an explanation of the name change in the next few days.
