title: aspnet_regIIS.exe -i does not add aspx to scriptmaps
body: <p>After installing asp.net (and aspnet_regIIS.exe -i) the site doesn't accept my default.aspx page. When trying to access it I get a 404.
  When hitting directly to my mvc pages (/search.mvc for example) it works like a charm.</p>
  
  <p>We checked the website configuration and noted that there are no .aspx references in the scriptmaps node.</p>
  
  <p>What am I missing?</p>
