Asp.NET MVC 2 DataAnnotations UpdateModel <T> Validation

I am trying to use DataAnnotations to add validation to my models in asp.NET MVC 2 RC2 using TryUpdateModel

        var user = UserManager.Find(id);

        this.TryUpdateModel<IProvisioningObject>(user, form.ToValueProvider());

This updates the model, but validation is never called. I also tried using TryUpdateModel (which is a direct user type) without using a form value provider, using ProvisioningObject directly (which has validation metadata), to no avail.

Google for examples only gives me ways to use DataAnnotations by binding via parameter

public ActionResult Update(User user)

What I don't like about update scripts.

Any tips and / or solutions?

EDIT My objects are objects created automatically using the WCF service.

// Controller action
