The problem for me was a new server that System.Web.Routing was of version 3.5 while web.config requested version 4.0.0.0. The resolution was

%WINDIR%\Framework\v4.0.30319\aspnet_regiis -i

%WINDIR%\Framework64\v4.0.30319\aspnet_regiis -i

Having this in Global asax cs solved it for me   protected void Application Start         AreaRegistration RegisterAllAreas        RouteConfig RegisterRoutes RouteTable Routes

My solution  after trying EVERYTHING   Bad deployment  an old PrecompiledApp config was hanging around my deploy location  and making everything not work   My final settings that worked    IIS 7 5  Win2k8r2 x64   Integrated mode application pool Nothing changes in the web config - this means no special handlers for routing  Here s my snapshot of the sections a lot of other posts reference  I m using FluorineFX  so I do have that handler added  but I did not need any others    lt system web gt     lt compilation debug  true  targetFramework  4 0    gt     lt authentication mode  None   gt      lt pages validateRequest  false  controlRenderingCompatibilityVersion  3 5  clientIDMode  AutoID   gt     lt httpRuntime requestPathInvalidCharacters     gt      lt httpModules gt       lt add name  FluorineGateway  type  FluorineFx FluorineGateway  FluorineFx   gt     lt  httpModules gt   lt  system web gt     lt system webServer gt       lt  -- Modules for IIS 7 0 Integrated mode -- gt       lt modules gt         lt add name  FluorineGateway  type  FluorineFx FluorineGateway  FluorineFx    gt       lt  modules gt        lt  -- Disable detection of IIS 6 0   Classic mode ASP NET configuration -- gt       lt validation validateIntegratedModeConfiguration  false    gt     lt  system webServer gt   Global ashx   only method of any note   void Application Start object sender  EventArgs e           Register routes        System Web Routing Route echoRoute   new System Web Routing Route               message              the default value for the message           new System Web Routing RouteValueDictionary        message                     any regular expression restrictions  i e       d   4    means  does not start with number  at least 4 chars           new System Web Routing RouteValueDictionary        message        d   4                   new TestRoute Handlers PassthroughRouteHandler                  System Web Routing RouteTable Routes Add echoRoute      PassthroughRouteHandler cs - this achieved an automatic conversion from http   andrew arace info stackoverflow to http   andrew arace info  stackoverflow which would then be handled by the default aspx   public class PassthroughRouteHandler   IRouteHandler        public IHttpHandler GetHttpHandler RequestContext requestContext            HttpContext Current Items  IncomingMessage     requestContext RouteData Values  message            requestContext HttpContext Response Redirect       HttpContext Current Items  IncomingMessage    true           return null

Just found that lines below must be added to web config file  now everything works fine on production server too    lt system webServer gt     lt modules runAllManagedModulesForAllRequests  true   gt      lt remove name  UrlRoutingModule   gt         lt  modules gt   lt  system webServer gt

The solution suggested    lt system webServer gt     lt modules runAllManagedModulesForAllRequests  true   gt       lt remove name  UrlRoutingModule   gt         lt  modules gt   lt  system webServer gt    works  but can degrade performance and can even cause errors  because now all registered HTTP modules run on every request  not just managed requests  e g   aspx   This means modules will run on every  jpg  gif  css  html  pdf etc   A more sensible solution is to include this in your web config    lt system webServer gt     lt modules gt       lt remove name  UrlRoutingModule-4 0    gt       lt add name  UrlRoutingModule-4 0  type  System Web Routing UrlRoutingModule  preCondition      gt     lt  modules gt   lt  system webServer gt    Credit for his goes to Colin Farr  Check-out his post about this topic at http   www britishdeveloper co uk 2010 06 dont-use-modules-runallmanagedmodulesfo html
