I have a route defined like so:

                name: "Members API",
                routeTemplate: "api/members/{username}",
                defaults: new { controller = "Members", username = RouteParameter.Optional });

I have a "PUT" method in my controller like so:

public void Put(string username, Member member)

Now when I make an Http PUT request with a url such as


And a JSON Payload such as

"firstName":"Shiv","lastName":"Kumar", "username": "xxxxx"

The username parameter to the method has a value of "xxxxx" instead of "skumar". I would expect that the parameter comes in as whatever is on the url while the Member parameter gets populated using only the JSON payload.
