hi
in BundleConfig.cs file i create a bundles :

bundles.Add(new Bundle("~/bundles/jquery").Include(
                      "~/Scripts/jquery-{version}.js",
                      "~/Scripts/jquery-migrate-1.2.1.js",
                      "~/Scripts/custom.js",
                      "~/Scripts/jquery.tabs.setup.js",
                      "~/Scripts/jquery-prettyPhoto.js",
                      "~/Scripts/tinymce/jquery.tinymce.js",
                      "~/Scripts/tinymce/tiny_mce.js",
                      "~/Scripts/otf.js"
                      ));

and in _Layout.cshtml i writed this code:

@Scripts.Render("~/bundles/jquery")
@Styles.Render("~/Content/css")

it's work well when i use visual studio 2012 all js and css file loaded completely but when i upload my web site in my Host js and css not loaded completely and in view page source i see just :

<script src="/bundles/jquery?v=LP3rXi_N6xYJxm_-rpBVdxByPgYGeZwklRBTd7uXHZQ1"></script>

   <script src="/bundles/modernizr?v=dtqgLuAIjLqkWUg5M8PJAS3lUdIXrYzWCsdNomXHMGk1"></script>

   <script src="/bundles/jqueryval?v=QqAmIKObfP2Ew0RC7FZiPTlveyDpGRejUBAPO8IekIY1"></script>




   <link href="/Content/css?v=muHFqnUUc3VOc1ulG4430C4L5EsTCQ7L3jUUnG_LXm41" rel="stylesheet"/>
