title: recent added record not included in CrmOrganizationServiceContext ContactSet
body: <p>When I run the code below it adds the record BUT it doesn't get included in the ContactSet at first. Only if I run it again it shows on the ContactSet, and it shows once, besides the fact that I get the record duplicated. Any idea why the ContactSet doesn't show the new record created?</p>
  
  <pre><code>       var xrm = new XrmServiceContext("Xrm");
  
          //Create a new contact called Allison Brown.
          var testContact = new Contact
          {
              FirstName = "Allison",
              LastName = "Brown",
              Address1_Line1 = "101 W 1st St",
              Address1_City = "Los Angeles",
              Address1_StateOrProvince = "CA",
              Address1_PostalCode = "90001",
              Telephone1 = "310-111-1111",
              EMailAddress1 = "allisonbrown@aol.com"
          };
  
          xrm.AddObject(testContact);
          xrm.SaveChanges();
          var exampleContacts = xrm.ContactSet.Where(c =&gt; c.EMailAddress1.EndsWith(".com"));
          return View(exampleContacts);
  </code></pre>
