myConfig.AddTranslationProvider(new MyCustomTranslationProvider());
});

Route Convention Attribute Attribute

public class MyRouteConventionAttribute : RouteConventionAttributeBase
{
public override IEnumerable
GetRouteAttributes(MethodInfo actionMethod)
{
// TODO: Yield IRouteAttributes (GET/POST/PUT/DELETE/Route).
}
}

Wc can map our ASP.NET MVC areas to subdomains by using the Subdomain property of the RouteAreaAttribute. Doing so ensures that the routes for the area are matched only when requests are made to the specified subdomain. Here’s how:

[RouteArea(“Users”, Subdomain = “users”)]
public class SubdomainController : Controller
{
[GET(“”)]
public ActionResult Index() { /* … */ }
}
