title: MVC Bundling - Failed to load resource
body: <p>What could be causing this?  I'm working with a DurandalJS project that builds and runs locally just fine.  When I try to deploy to an Azure Website, the app publishes but fails in the browser with: </p>
  
  <blockquote>
    <p>Failed to load resource: the server responded with a status of 404
    (Not Found)
    <a href="http://appsite.azurewebsites.net/Scripts/vendor.js?v=KJCisWMhJYMzhLi_jWQXizLj9vHeNGfm_1c-uTOfBOM1">http://appsite.azurewebsites.net/Scripts/vendor.js?v=KJCisWMhJYMzhLi_jWQXizLj9vHeNGfm_1c-uTOfBOM1</a></p>

  <p>I haven't customized any of the bundling.</p>

  <p>In my html page I use this: </p>
  
  <pre><code>@Scripts.Render("~/Scripts/vendor.js")
  </code></pre>
  
  <p>This is preventing required libraries (like knockout) from loading.  Could it be something in my web.comfig?  Any tips would be awesome.  </p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>I can reproduce the exact issue locally if I do the following: </p>
  
  <pre><code>new ScriptBundle("~/Scripts/vvendor.js")  // change the virtual output directory here
  </code></pre>
  
  <p>I think this means the view can't find the directory when it's published for some reason... </p>
