John Lam talks about an NUnit 2.0 gotcha he found. 

If you are using the 1.1 .Net Framework, you will need to add a setting to the nunit-console.exe.config and nunit-gui.exe.config files to use the correct CLR version (v1.1.4322 for 1.1).  Add this to the above files:

  <startup>
    <supportedRuntime version="v1.1.4322" />
  </startup>

Thanks John.
