How do I add an Interface to a MS Proxy Class for MS-CRM 2013

Question

So I have a MS Dynamics CRM 2013 installation that I'm trying to integrate some items to and want to send some data. I have an interface (IAccnt) that I want to apply to the proxy class generated when I added the service refrence to ...XRMServices/2011/OrganizationData.svc/ (I added on a partial class)

When I initially added the interface (it only had "Name" and "AccountNumber") everything was going along well (ie able to save items) ... I added a new item to the interface that didn't have a direct corollary ("Email") but that did map (so the getter and setter just passed data to and from this.EMailAddress1)

With that change I now get the following error on save: Error processing request stream. The property name 'Email' specified for type 'Microsoft.Crm.Sdk.Data.Services.Account' is not valid.

This is unexpected as I'm sending a Microsoft.Crm.Sdk.Data.Services.Account object so it shouldn't have Email on it? And regardless I should be able to send more information than needed? Is there something I need to do to be able to add an Interface to a proxy class and have the save still work?

I've tried adding [XmlIgnore] and [IgnoreDataMember] on the public property implementation of Email, but same result ... Something like that (ie "ignore these properties when ".AddToAccountSet"/".SaveChanges()" would probably solve this isssue?

Interface Code

public interface IMyAccount
{
   string Name { get; set; }
   string Email { get; set; }
}

Partial Class (partial on the proxy class created from service reference)

namespace MyNamespace.CustomerRelationshipManagement.MicrosoftDynamics.CrmServiceReference
{
    public partial class Account : MyNamespace.Interfaces.IMyAccount
    {
        public string Email { get { return this.EMailAddress1; } set { this.EMailAddress1 = value; } }
    }
}

Where the error is raised from (attempt to add account)

var crmUri = new Uri("http://crminstallation/XRMServices/2011/OrganizationData.svc/");
var crmService = new CrmServiceReference.CrmInstallationContext(crmUri);
crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;

var crmMyAccount = new CrmServiceReference.Account();
crmMyAccount.Name = "Test Account";
crmMyAccount.Email = "myemail@mydomain.com";

crmService.AddToAccountSet(crmMyAccount);
crmService.SaveChanges();

If Email is removed from the interface and from the partial class then it works (in that it saves a new account to CRM)

Answer 1

The Account entity has no Email field. It has an emailaddress1 one though, try with that
