A breaking change in .NET 4.5 (RC) creates a 404 error while trying to access resources underneath mini-profiler-resources. This appears to affect both MVC 3 and MVC 4 projects targeting .NET 4.5.

Setting `runAllManagedModulesForAllRequests="true"` will not fix the problem. I was finally able to make it work by including:

```
<system.webServer>
  ...
  <handlers>
    <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
  </handlers>
</system.webServer>

```

Can this behavior be fixed, or can MiniProfiler.MVC be updated to add this section to web.config by default?
