Using asp.net Mvc3 RTM, IIS7.

I'm getting flooded with errors like this one:

System.Web.HttpException A public action method 'Application' was not found on controller 'Interreg.Web.Controllers.ApplicationsController'.
System.Web.HttpException (0x80004005): A public action method 'Application' was not found on controller 'Interreg.Web.Controllers.ApplicationsController'.

at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Controllers and actions changes, they surely do exist and app does not crash - user does not see yellow screen of death.

I suspect it has something to do with static resource loading (images, scripts), probably routing.

Any ideas what's wrong, what can cause this?

  1. Verify the type of request.(Either GET or POST)
  2. Add [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)] attributes at above the method
  3. If Application method was returning the Json result add JsonRequestBehavior.AllowGet behavior in return Json. Eg: return Json(zeroResult, JsonRequestBehavior.AllowGet);

It may be what you say. I'd suggest to check IIS log for queries against /Application to see where is that URL and where it's called.

Another option is navigating while in debug mode and in that case exception should pause the execution in Visual Studio.

Good luck!
