title: Include files in bundle across projects
body: <p>I have a Visual Studio solution witch contains 2 projects (websites):</p>
  
  <pre><code>Solution
    - Project A
        - App_Start
           - BundleConfig.cs
        - Scripts
  
    - Project B
        - App_Start
        - Scripts
           - my_file.js
  </code></pre>
  
  <p>Is there a way to include files from <code>Project B</code> at <code>Project A</code>, using bundles?:</p>
  
  <pre><code>public static void RegisterBundles(BundleCollection bundles)
  {
      bundles.Add(
           new ScriptBundle("~/bundles/my_bundle")
                // This obviously doesn't work
                .Include("~/../Scripts/my_file.js")
  
                // Neither does this
                .Include("../../../Scripts/my_file.js")
    );
  }
  </code></pre>
