    copied!<p>Has something changed with the rtm bits regarding the validation of models.</p> <p>I have a simple viewmodel that looks like</p> <pre><code> public class ProductViewModel { [Required] [DataMember(IsRequired = true)] public int ProductTypeId { get; set; } public string Product { get; set; } } </code></pre> <p>(I just added the DataMember(IsRequired = true) as the error message I get says to use it to fix the problem. However no joy)</p> <p>Within my controller the model state is telling me model is valid however when I try passing the model to my api using RestSharp I get the following error.</p> <blockquote> <p>{"Message":"An error has occurred.","ExceptionMessage":"Property 'ProductTypeId' on type 'Mine.Model.Model' is invalid.
