Voorbeeld: Een realtime-werkstroom in code maken
Gepubliceerd: november 2016
Is van toepassing op: Dynamics CRM 2015
Deze voorbeeldcode is van toepassing op on–premises Microsoft Dynamics CRM 2015. De complete broncode voor het voorbeeld is te vinden op de volgende locatie in het Download het Microsoft Dynamics CRM SDK-pakket. -pakket:
SampleCode\CS\Process\Workflows\CreateRealtimeWorkflow.cs
Download het Microsoft Dynamics CRM SDK-pakket.
Vereisten
U moet ondersteuning voor aangepaste XAML-werkstromen op uw on-premises server inschakelen. Zie XAML-werkstromen in- of uitschakelen voor meer informatie.Voor meer informatie over de vereisten voor het uitvoeren van de voorbeeldcode in deze SDK, zie Het voorbeeld en de helpercode gebruiken.
Demonstreert
Het volgende voorbeeld laat zien hoe u een realtime-werkstroom kunt maken in code in plaats van via de interactieve werkstroomontwerper in de webtoepassing. Dit voorbeeld werkt alleen met een on-premises of IFD-installatie (Internet Facing Deployment) van Microsoft Dynamics 365 omdat aangepaste XAML-werkstromen niet worden ondersteund in Microsoft Dynamics CRM Online.
