errore Salire su SaveChanges mentre updateObject con soggetti legati presto CRM SDK 2015

Question

sto errore di salire sul xrm.saveChanges() se faccio updateObject mentre AddObject sta lavorando bene, inizialmente ho pensato che è a causa del contesto come discusso in questo thread Dynamics CRM saving Entity Changes - Getting Errors ma ho provato tutte le opzioni discusse qui https://msdn.microsoft.com/en-us/library/gg695783.aspx ma nulla ha aiutato.

Il mio codice è `

 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); 
     } 
    } 

L'errore che sto ottenendo è

Answer 2

è necessario abilitare entità presto legati chiamando

_serviceProxy.EnableProxyTypes(); 

sull'istanza OrganizationServiceProxy.

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(); 
}

Rigenerare i tipi di proxy dovrebbe risolvere il problema.

Inoltre, dal momento che sei online, assicurati di avere l'ultima versione dell'SDK (non c'è bisogno di dar loro la caccia, sono disponibili su NuGet).
