title: How do I access RouteTable.Routes.MapHttpRoute?
body: <p>I have a Web Forms app that I created a few months ago and I added a Web API controller. I tried to use the 'automatic' routing that I saw in a presentation recently, but all I got was a 404. Then I tried to add routing for the Web API controller in my Global.asax using MapHttpRoute, as I've seen in several tutorials. However, even after adding <code>Imports System.Web.Http</code> to the file, the project will not recognize <code>RouteTable.Routes.MapHttpRoute()</code> I have tried adding other namespaces and ensuring that I have all the necessary Nuget packages, but I still am unable to set up routing for the Web API controller. Does anyone have a recommendation of where to start?</p>
