Uzyskiwanie błąd na SaveChanges podczas UpdateObject z wcześnie związane jednostki CRM SDK 2015

Question

Dostaję błąd na xrm.saveChanges() Jeśli zrobię UpdateObject podczas AddObject pracuje bez zarzutu, initally Myślałem, że to dlatego, że z kontekstu jak omówiono w tym wątku Dynamics CRM saving Entity Changes - Getting Errors ale wypróbowałem wszystkie opcje omówione tutaj https://msdn.microsoft.com/en-us/library/gg695783.aspx ale nic nie pomogło.

Mój kod jest `

 using (var xrm = new XrmServiceContext("Xrm")) 
     { 
      WriteExampleContacts(xrm); 

      //Create a new contact called Allison Brown. 
      var allisonBrown = new Xrm.Contact 
      { 
       FirstName = "Allison", 
       LastName = "Brown", 
       Address1_Line1 = "23 Market St.", 
       Address1_City = "Sammamish", 
       Address1_StateOrProvince = "MT", 
       Address1_PostalCode = "99999", 
       Telephone1 = "12345678", 
       EMailAddress1 = "allison.brown@example.com" 
      }; 

      xrm.AddObject(allisonBrown); 
      xrm.SaveChanges(); 

      WriteExampleContacts(xrm); 



     //Update the e-mail address of Allison Brown and link her to the account Contoso. 

     //allisonBrown.contact_customer_accountsParentCustomerAccount = account; 
     using (var xrm2 = new XrmServiceContext("Xrm")) 
     { 

      xrm.Detach(allisonBrown); 
      xrm2.Attach(allisonBrown); 


      allisonBrown.EMailAddress1 = "allison.brown@contoso.com"; 
      xrm2.UpdateObject(allisonBrown); 
      xrm2.SaveChanges(); 
     } 

     //Update the contact record and then commit the changes to Microsoft Dynamics CRM. 
     } 

     Console.WriteLine("Press any key to exit."); 
     Console.ReadKey(); 
    } 

    /// <summary> 
    /// Use all contacts where the email address ends in @example.com. 
    /// </summary> 
    private static void WriteExampleContacts(XrmServiceContext xrm) 
    { 
     var exampleContacts = xrm.ContactSet 
      .Where(c => c.EMailAddress1.EndsWith("@example.com")); 

     //Write the example contacts. 
     foreach (var contact in exampleContacts) 
     { 
      Console.WriteLine(contact.FullName); 
     } 
    }

Answer 2

Musisz włączyć wcześnie związane jednostki dzwoniąc

_serviceProxy.EnableProxyTypes(); 

na OrganizationServiceProxy instancji.

var cred = new ClientCredentials(); 
cred.UserName.UserName = "your username"; 
cred.UserName.Password = "your password"; 
using (var _serviceProxy = new OrganizationServiceProxy(new Uri("https://[your organization service url here]"), null, cred, null)) 
{ 
    _serviceProxy.EnableProxyTypes(); // Will throw error on save changes if not here 
    var context = new CrmServiceContext(_serviceProxy); 

    context.AddObject(new Opportunity() { Name = "My opportunity" }); 

    context.SaveChanges(); 
}

Regeneracja typów proxy powinna rozwiązać problem.

Ponadto, ponieważ jesteś online, upewnij się, że masz najnowszą wersję SDK (nie ma potrzeby, aby je wyłapać, są one dostępne w NuGet).
