Applies To: Dynamics CRM 2015

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 2015 and Microsoft Dynamics CRM Online 2015 Update. 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

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.

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

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

using Microsoft.Xrm.Sdk;

    /// </summary>
    /// <remarks>This sample requires that a service endpoint be created first, and its ID passed
    /// to the plug-in constructor through the unsecure configuration parameter when the plug-in
    /// step is registered.</remarks>

            }
        }

        public void Execute(IServiceProvider serviceProvider)

            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            if (tracingService == null)
                throw new InvalidPluginExecutionException("Failed to retrieve the tracing service.");

            IServiceEndpointNotificationService cloudService = (IServiceEndpointNotificationService)serviceProvider.GetService(typeof(IServiceEndpointNotificationService));
            if (cloudService == null)
                throw new InvalidPluginExecutionException("Failed to retrieve the service bus service.");

            try

                string response = cloudService.Execute(new EntityReference("serviceendpoint", serviceEndpointId), context);
                if (!String.IsNullOrEmpty(response))
                {
                    tracingService.Trace("Response = {0}", response);
                }
                tracingService.Trace("Done.");
            }
            catch (Exception e)
            {
                tracingService.Trace("Exception: {0}", e.ToString());
