title: Visual Studio 2010 script debugger doesn't work for me
body: <p>I just installed VS 2010 Beta 2 and wanted to play with an ASP.NET MVC 2 project.  I simply added some script (<code>alert('hello');</code>) into the Home controller's index.aspx view, and I can see it executing.  When I try to set a breakpoint, however, it never gets hit.  I also tried to use the "debugger" keyword, and when I do, I get a disappointing "there is no source code available for the current location" message.  I also get this message when I try to independently attach to an IE process where my app is running.</p>
  
  <p>What do I need to do to get a friendly script debugging experience?  (I have successfully used Firebug to debug this, but for some reason I prefer the VS debugger.)</p>
  
  <p>Here are some details of my configuration:</p>
  
  <ul>
  <li>I am launching my stuff in VS 2010 Beta 2.</li>
  <li>IE8 version 8.0.7600.16385 is my default browser.</li>
  <li>The "Disable script debugging (Internet Explorer)" advanced option is unchecked.</li>
  <li>The "Disable script debugging (Other)" option is unchecked.</li>
  <li>In my ASP.NET MVC 2 project's "web" properties tab, the ASP.NET debugger is checked.  All others are unchecked.</li>
  <li>Visual Studio 2008 script debugging seems to work just fine.</li>
  </ul>
