title: Why is jqueryval bundle rendering empty?
body: <p>I am trying to render a script bundle but it is coming up empty.</p>
  
  <p>Here's the script bundle declaration in BundleConfig.cs</p>
  
  <pre><code>bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                      "~/Scripts/jquery-{version}.js"));
  
  bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                    "~/Scripts/modernizr-*"));
  
  bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                    "~/Scripts/bootstrap.js",
                    "~/Scripts/respond.js"));
  
  bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/jquery.unobtrusive.ajax*",
                    "~/jquery.validate.unobtrusive.bootstrap*"));
  </code></pre>
  
  <p>And in my view</p>
  
  <pre><code>@Scripts.Render("~/bundles/jquery")
  @Scripts.Render("~/bundles/bootstrap")
  @Scripts.Render("~/bundles/modernizr")
  @Scripts.Render("~/bundles/jqueryval")
  </code></pre>
  
  <p>But when I load the page, the jqueryval script comes up empty.</p>
  
  <pre><code>&lt;script src="/bundles/jquery?v=Nsx6sB8o7LJCR51P5u-dfe-6LePnt87pD0P5VTJ-0wI1"&gt;&lt;/script&gt;
  
  &lt;script src="/bundles/bootstrap?v=XkxfR798CUJPhMhSd0B8VYgZWSNOTtLvz6047jf84wQ1"&gt;&lt;/script&gt;
  
  &lt;script src="/bundles/modernizr?v=K-FFpFNtIXPUlQamnX3qHX_A5r7TM2xbAgcuEmpm3O41"&gt;&lt;/script&gt;
  
  &lt;script src="/bundles/jqueryval?v="&gt;&lt;/script&gt;
  </code></pre>
  
  <p>The debugger in Firefox says returns a 200 status when retrieving the files for the bundle, but the filesize is 0.</p>
