Hi.

I have a small isuse regarding an interface.

Consider this code:

[HttpPost()]
public void Update(IAuctionItem item) {
    RedirectToAction("List");
}

Whenever I call this I get an exception saying I can't create an instance of type which i totally correct. But is there a way of telling what the interface should map to without actually using the concrete type ?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
