Mike, any chance you'd care to add this to WebApiContrib? :) github.com/.../WebAPIContrib

@Dave - yes. It's very similar to MVC. I'll write up a blog about it.

There are several ways to do it. One way is to add a [ModelBinder] attribute on the parameter callstite.

GetContacts([ModelBinder(typeof(MyModelBinder)] OAuthToken authToken)

In the beta, you must supply a model binder provider. In the lastest sources, you can supply a IModelBinder just like MVC.

Can I use a modelbinder or a formatter to change the type of a parameter / add remove parameters?

ie. I have a method

List<Contact> GetContacts(string authToken)

where authToken is an OAuthToken which allows me to lookup an actual user account and fetch user-account-info

. In fact, I have a lot of service methods which accept this authToken......ALMOST every service method in fact..... I don't want to have to convert authToken into Account in every method. In fact, I just want *some magic* which will take in the authToken, validate it and either return an error to the client or pass the looked-up-Account instance to the downstream method.....

HttpRequest -> List<Contact>GetContacts(string authToken) -> *Some magic* -> List<Contact>GetContacts(Account acct)

How do I go about achieving this?
