# NUnit 2.2.4: .NET 2.0 Support, Extensibility Support and new Asserts and Attributes

By Roy Osherove December 17, 2005 In [Agile Israel News](https://osherove.com/blog/category/agile-israel-news), [Agile Related](https://osherove.com/blog/category/agile-related), [Cool Tools](https://osherove.com/blog/category/cool-tools), [Team Agile News](https://osherove.com/blog/category/team-agile-news)

**Historical article** · Originally published December 17, 2005; technical details may be outdated.

Got this from [Charlie Poole](http://nunit.com/blogs) today:

We just released NUnit 2.2.4, the first production release of NUnit since
2.2 was released in August 2004. That means it's the release we recommend you use now - as opposed to all the warnings we give with our development releases.

If you haven't followed the development releases, here are a few highlights of what's new, as compared to NUnit 2.2:

- NUnit 2.2.4 runs under .Net 2.0 and works with VS2005. If you work exclusively with .Net 2.0, you can download a version that is actually built with that framework version, which eliminates dealing with the config file.
- You can run tests built against older versions - 2.0 or later - of NUnit without recompiling. As a bonus, you can run tests built against CSUnit without recompiling.
- A number of new Asserts and Attributes have been added. It is now much easier to create your own custom Asserts while still taking advantage of NUnit's built-in error message formatting.
-    An extensibility mechanism allows you to define your own attributes for test fixtures and cases that behave in non-standard ways. \[This feature is Still a bit experimental, and will appear in final form in the 2.4 release.
- Documentation is substantially improved and is provided as a set of html files. The packaged documentation includes only version-specific details, with info that may change over time, such as contacts, kept on the web site.

You can read the full release notes at
[http://nunit.com/testweb/index.php?p=releaseNotes&r=2.2.4](http://nunit.com/testweb/index.php?p=releaseNotes&r=2.2.4). Note that the nunit.org site has not yet been updated to reflect this release.
