Sample: Azure aware custom plug-in

 

Applies To: Dynamics CRM 2013

This is a sample custom plug-in that can post the pipeline execution context to the Microsoft Azure Service Bus.

This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:

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

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

Demonstrates

The plug-in demonstrates how to obtain the execution context and the tracing service from the service provider parameter of the Execute method. The plug-in then posts the context to the Microsoft Azure Service Bus endpoint and writes information to the trace log to facilitate debugging.

Example

using System;
using System.Diagnostics;
using System.Threading;
using System.Runtime.Serialization;

using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;

using Microsoft.Xrm.Sdk;

    /// to the plug-in constructor through the unsecure configuration parameter when the plug-in
