如果作为子应用程序部署在IIS中，则ASP.NET Web API中的路由问题

Question

I have a solution in VS2013 with multiple ASP.NET Web applications. I have added an ASP.NET WebAPI project in the same solution.

After I deployed the WebAPI as a child application in IIS I got the following error:

Multiple types were found that match the controller named 'Account'. This can happen if the route that services this request ('Account/Register') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'Account' has found the following matching controllers:
Proj1.Controllers.AccountController
Proj2.Controllers.AccountController

I have tried adding a default namespace to the RouteConfig.cs like so:

routes.MapRoute(

                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                namespaces: new string[] { "Proj1.WebAPI.Controllers" }

            );

but I still get the same error.

Any ideas?

I just needed to add this to my WebApiConfig.cs

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "webapi/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        **config.Routes.MapHttpRoute(
            name: "Admin",
            routeTemplate: "{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }**
        );

    }

Works perfectly now!
