Jonathan,
<br>
<br>I currently have <a title="MbUnit, Generating Unit Testing and Model Based Testing Framework for .NET Framework" href="http://mbunit.tigris.org" target="_blank">MbUnit</a>-bin-2.15.1-StrongRelease installed. I notice that it is a lot bigger than the 2.8 version. Should I uninstall what I already have?

Yes, just replace the files. 2.18 is smaller because NGraphviz (1.2Mb) is not needed anymore.

Jonathan,
<br>some of us have been trying to download the 2.20 release - it fails after downloading about 40%..
<br>
<br>is there another site we can download this or an earlier version from?
<br>
<br>thanks
<br>

I've uploaded version 2.20 on my blog at

<br>This is temporary because <a title="MbUnit, Generating Unit Testing and Model Based Testing Framework for .NET Framework" href="http://mbunit.tigris.org" target="_blank">MbUnit</a> should ship with <a title="" href="http://weblogs.asp.net/nunitaddin/" target="_blank">NUnitAddIn</a> in the next release.
