We are migrating our existing web applications from Server 2008 with IIS 7 to Server 2012 with IIS 8. When I set "Preload Enabled" to true the app pool serving the process immediately crashes with the below error.

I have this in the system.webserver node of my web.config:

<applicationInitialization remapManagedRequestsTo="In_LoadBalancer_Rotation.html" skipManagedModules="true" >
        <add initializationPage="/Default.aspx" />
 </applicationInitialization>

I also have the app pool for the application set to "AlwaysRunning".

As soon as I comment out the above section in the web.config and set "Preload Enabled" to false everything works like a charm.

We use Helicon's ISAPI_Rewrite to get Apache style htaccess rewrites in IIS. I updated to the latest version and the issue is resolved.
