title: StructureMap Exception after adding the WebApi.HelpPage to a webApi project
body: <p>I followed the instructions here to add the webApi.HelpPage area and views to an existing project, which uses structureMap - but when accessing the /Help url:</p>
  
  <pre><code>StructureMap Exception Code:  202 No Default Instance defined for PluginFamily System.Web.Http.HttpRouteCollection, System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
  </code></pre>
  
  <p>So I'm missing something on the structureMap configure:</p>
  
  <pre><code>ObjectFactory.Configure(x =&gt; x.Scan(scan =&gt;
              {
                  scan.TheCallingAssembly();
                  scan.AssembliesFromApplicationBaseDirectory();
                  scan.AddAllTypesOf&lt;IHttpModule&gt;();
                  scan.WithDefaultConventions();
              }));
  </code></pre>
  
  <p>Can anyone point a structureMap newbie in the right direction?</p>
