Question

Let’s say the Action below is exposed via REST service and is called from a different appliation how would it handle the posted data/object?

Should I use Create(FormCollection collection) here?

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Member member)
{
….
}

I’d suggest using a model, but one in which all of the parameters are nullable and use the RequiredAttribute for actual, required parameters. This would allow your method to accept invalid requests — with missing or extra data — yet have valid data bound to the model. For invalid data, you can supply error returns instead of presuming default values for non-nullable properties. Using the model binding validation architecture provides a convenient way to make sure that the request is legal. It would be up to you how you want to handle “extra” data supplied by the request — I’d say ignore it.
