Esempio - Autenticare gli utenti tramite i servizi Web di Microsoft Dynamics CRM

 

Data di pubblicazione: novembre 2016

Si applica a: Dynamics CRM 2015

In questo esempio viene illustrato come autenticare un utente con una distribuzione di Microsoft Dynamics 365 e ottenere un riferimento ai servizi Web. Questo esempio include il supporto per gli utenti di Microsoft Office 365 di cui è stato eseguito il provisioning in Microsoft Dynamics CRM Online.

Scarica il pacchetto SDK di Microsoft Dynamics CRM. È disponibile nel percorso seguente nel pacchetto di download:

SDK\SampleCode\CS\GeneralProgramming\Authentication\AuthenticateWithNoHelp\AuthenticateWithNoHelp.cs

Dimostra

In questo esempio viene illustrato come autenticare un utente con una distribuzione di Aggiornamento di Microsoft Dynamics CRM 2015 e Microsoft Dynamics CRM Online 2015 ed effettuare chiamate ai servizi Web. Questo esempio non si basa sul codice dell'helper CrmServiceHelpers.cs. Per un esempio in cui non viene utilizzato il codice dell'helper, vedere Esempio - Guida introduttiva per Microsoft Dynamics CRM.
