Why do my SpecFlow tests not show up in Visual Studio Test window?
<p>I have gone through the Getting Started tutorial for SpecFlow.
Everything worked fine except that I have the @SpecRun test because I have not entered a demo key.</p>

<p>But in our main project we use NUnit instead of SpecFlow+ Runner.
So I tried to mimic that project.  If you use NUnit you won't need the demo key.
So I changed the Unit Test Provider to:</p>

<pre><code>&lt;specFlow&gt;
  &lt;unitTestProvider name="NUnit" /&gt;
&lt;/specFlow&gt;
</code></pre>

<p>I also compared my tutorial references to the main project's references.
I find that I can take out TechTalk.SpecRun and the project will still compile.
Of course TechTalk.SpecFlow is needed.</p>

<p>If I take out SpecRun.SpecFlowPlugin, no tests show up except @SpecRun which is the tests delay without the demo key.</p>

<p>I also see in the main project a csharp file called: SpecFlowNUnitExtension.cs.
I brought in this file but my tests still do not show up in the Visual Studio Test window.
Is there something I need to do to register this file?</p>
