Azure Web Role MVC5 does not start in integrated mode - asp.net

Question

After upgrade my Azure Web role project with MVC4 and SDK 2.2 to SDK 2.4 and MVC5, starts the application only in the emulator, but not in the cloud (empty page or "Page can not displayed").
After remote login on the VM and changing the application pool mode from integrated to classic, works the page also with the new settings. Changes of the handler settings in the web.config were unsuccessful.
Current web.config with MVC5 and SDK2.4:
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules>
<add name="PageSpeedModule" type="CheckMyBus.Web.Frontend.Modules.ProtectionModule" preCondition="managedHandler" />
</modules>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" /><remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

Last web.config works fine with MVC4 and SDK2.2:

Can everyone help me?

Answer 1

Having upgraded to MVC5 manually I didn't realize that the pages-clause in the Views weg.config had THREE references to System.Web.Mvc. That made the web role recyle forever.
Fixing this solved my rcycling issue.
