title: routing not working whilst using iis instead of visual studio 2010's development server
body: <p>I have to deal with a legacy asp.net mvc web app (.net 4). It uses some customized routing, which works fine when I use visual studio 2010's development server. However, when I use iis instead (during debugging) it does not seem to work (never used iis during debugging before).</p>
  
  <p>The answer provided <a href="https://stackoverflow.com/questions/4428278/asp-net-4-routing-not-working-in-iis-7">here</a> does not seem to help. I already use:</p>
  
  <pre><code>&lt;system.webServer&gt;
      &lt;validation validateIntegratedModeConfiguration="false"/&gt;
      &lt;modules runAllManagedModulesForAllRequests="true"/&gt;
  &lt;/system.webServer&gt;
  </code></pre>
  
  <p>Is there any other reason why the routing may not work? Thanks!</p>
