Eksempel: Azure-følsom brugerdefineret plug-in

 

Udgivet: november 2016

Gælder for: Dynamics CRM 2015

Dette er en brugerdefineret eksempel-plug-in, der kan sende kørselskonteksten i pipelinen til Microsoft Azure-servicebus.

Denne eksempelkode er for Microsoft Dynamics CRM 2015 og opdatering til Microsoft Dynamics CRM Online 2015.Hent SDK-pakken til Microsoft Dynamics CRM. Den findes på følgende placering i downloadpakken:

SampleCode\CS\Azure\Plug-ins\SandboxPlugin.cs

Krav

Du kan finde flere oplysninger om kravene til kørsel af den eksempelkode, der findes i denne SDK, under Brug eksempel- og hjælpekoden.

Demonstrerer

Denne plug-in viser, hvordan du får kørselskonteksten og sporingstjenesten fra serviceudbyderparameteren for metoden Execute. Plug-in-programmet sender derefter konteksten til Microsoft Azure-servicebus-slutpunktet og skriver oplysninger til sporingslogfilen for at gøre fejlfinding nemmere.
