Can open generic methods be used with controlers?

Do you mean an open generic method, such as: public class MyController : Controller { public ActionResult SomeAction(T myParameter) { … } } Or a method that is generic on a class: public class MyController : Controller { public ActionResult SomeAction(T myParameter) { … } } Example #1 is not supported in ASP.NET MVC because we don’t know the type of “T”. Example #2 is technically supported in MVC since by the time we get to the method we already know what the “T” is. However, the default controller factory in ASP.NET MVC cannot construct generic classes. If you have a controller factory that can create MyController then ASP.NET MVC can call the action method on it.
