Problem getting NUnit started up for unit testing!

 I downloaded NUnit 2.4.8 and imported the framework into my test vb class and set up a simple example to see if it works.
 
Imports Microsoft.VisualBasic
Imports System
Imports NUnit.Framework
<TestFixture()> _
Public Class TestClass
    <Test()> _
Public Sub Test1()
        Assert.IsTrue(1 + 1 = 2)
    End Sub
End Class
 
Built it and went to Nunit, open project and wasnt sure what to import for my project, its a website so theres no .exe file for it. What do I actually open for it?
