Beispiel: Eindirektionaler Listener

 

Veröffentlicht: Januar 2017

Gilt für: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online

Diese Beispiel-Listener-Anwendung registriert ein Remote-Dienst-Plug-In, das immer dann ausgeführt wird, wenn eine Microsoft Dynamics 365-Nachricht an einen eindirektionalen Endpunkt auf dem Microsoft Azure Service Bus gesendet wird. Wenn das Plug-In ausgeführt wird, gibt es an die Konsole den Inhalt des in der Nachricht enthaltenen Microsoft Dynamics 365-Ausführungskontexts aus.

Anforderungen

Dieser Beispielcode ist für Microsoft Dynamics 365 und Microsoft Dynamics 365 (online).Laden Sie das Microsoft Dynamics CRM SDK-Paket herunter. Dieser Code ist an folgender Position im Downloadpaket verfügbar:

SDK\SampleCode\CS\Azure\OneWayListener\OneWayListener.cs

Demonstriert

Dieses Beispiel zeigt, wie ein Microsoft Azure Service Bus-Listener für einen eindirektionalen Endpunktvertrag geschrieben wird.
