Question

Under ASP.NET MVC are you supposed to pick up QueryString params the same way you do in ASP.NET WebForms? or does the [AcceptVerbs(HttpVerbs.Get)] declaration get used somehow?

Answer 1

Query string parameters can be accepted simply by using an argument on the action – i.e.

public ActionResult Foo(string someValue, int someOtherValue) {...} 

which will accept a query like .../someroute?someValue=abc&someOtherValue=123

Other than that, you can look at the request directly for more control.
