System.Web.Routing.RouteCollection doesn't contain a definiton for "MapHttpRoute" - VS 2012, Web API

Question

I've just installed Visual Studio 2012 and started checking out MVC 4 and Web Api. I've created a new MVC 4 app with Web API. Based on some examples and tutorials I started configuring my routes with:

routes.MapHttpRoute(                 name: "Controller only",                 routeTemplate: "api/{controller}"             ); 

However, that results in an error that RouteCollection doesn't contain a definition for MapHttpRoute. Am I missing some DLLs installed? As far as I could see I have all the right DLLs and version installed.

Answer 1

I have solved it by adding a reference to System.Web.Http in RouteConfig.cs

Answer 2

Try referencing: System.Web.Http and System.Web.Http.WebHost.dll

Then add a using statement for namespace: System.Web.Http

Note: It could also be that your intellisense is acting up. In which case just go ahead and type your code manually and build.

Hope that helps
