Esempio: creare un flusso di lavoro in tempo reale nel codice
Data di pubblicazione: gennaio 2017
Si applica a: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Questo codice di esempio si applica a Microsoft Dynamics 365 in locale. Il codice sorgente completo per l'esempio è disponibile nel percorso seguente nel pacchetto di Scarica il pacchetto SDK di Microsoft Dynamics CRM. dell'SDK:
SampleCode\CS\Process\Workflows\CreateRealtimeWorkflow.cs
Scarica il pacchetto SDK di Microsoft Dynamics CRM.
Requisiti
È necessario abilitare il supporto ai flussi di lavoro personalizzati XAML nel server locale. Per ulteriori informazioni, vedere Disabilitare o abilitare i flussi di lavoro XAML.Per ulteriori informazioni sui requisiti per l'esecuzione del codice di esempio fornito nell'SDK, vedi Utilizzare il codice di esempio e dell'helper.
Dimostra
L'esempio seguente illustra come creare un flusso di lavoro in tempo reale in codice anziché utilizzare la finestra di progettazione dei flussi di lavoro interattiva nell'applicazione Web. Questo esempio funziona esclusivamente con una distribuzione locale o IFD di Microsoft Dynamics 365 perché i flussi di lavoro XAML personalizzati non sono supportati in Microsoft Dynamics 365 (online).
