You can use the Validate() method of the ApiController class to manually validate the model and set the ModelState.

public IHttpActionResult PostUser()
{
    User u = new User();
    u.Name = null;

    this.Validate(u);

    if (!ModelState.IsValid)
        return BadRequest(ModelState);

    return Ok(u);
}
