There are much longer more detailed ways involving editing the registry, running “devenv …” command-line stuff, etc. This is by far the fastest and easiest way:
0.a. Make sure you have the ASP.NET MVC 1.0 Framework installed. I’m a dummy and still had the Beta installed and was surprised when the project wouldn’t build. Then I realized my blunder.
0.b. Close any open instances of Visual Studio 2008
1. Go to this URL: http://blogs.msdn.com/webdevtools/archive/2009/04/28/updated-nunit-templates-for-asp-net-mvc-1-0-rtm.aspx
2. Click on the “NUnit Test Templates” link. Download the zipped file.
3. Unzip the file.
4. Run the installNUnit.cmd file.
That’s it. Done. Enjoy.
