MVC4 RC WebApi parameter binding

Question

I upgraded from MVC4 beta to RC and the latest autofac. The following action was binding properly, but now both parameters are null. I see they changed things about the Fo

Answer 1

Not really sure why the change from Beta, but I was able to make it work by changing the action signature to:

[HttpPost]    
RedirectModel MyAction(MyActionDTO dto)

and defining MyActionDTO as

 public class MyActionDTO 
 {
        public string value1 { get; set; }
        public string value2 { get; set; }
 }

It was throwing an exception about not being able to bind to multiple body parameters using the two string paramaters. I guess using the DTO object more closely represents what you're sending in the AJAX call (a JSON object).

Answer 2

When you want to avoid using a DTO object, try this:

[HttpPost]    
RedirectModel MyAction(dynamic value1, dynamic value2) {
    string sValue1 = value1;
    string sValue2 = value2;
