Question

我在线使用Microsoft Dynamics CRM 2016并尝试使用自定义工作流程活动中的Azure Service Bus relay。

我创建了一个自定义活动（基于CRM SDK中的AzureAwareWorkflowActivity）并注册了一个端点（详情如下）。工作流程执行以以下错误结束：

System.ServiceModel.FaultException`1 [Microsoft.Xrm.Sdk.OrganizationServiceFault]：50200：Bad Gateway，Resource：sb：//****.servicebus.windows.net/update*****。 TrackingId：b7681665 - **** SystemTracker：NoSystemTracker，时间戳：10/2016/2016下午2:15:45（故障细节等于Microsoft.Xrm.Sdk.OrganizationServiceFault）。

你知道如何解决这个问题吗？

工作流程活动

namespace Microsoft.Crm.Sdk.Samples
{
    /// <summary>
    /// This class is able to post the execution context to the Windows Azure 
    /// Service Bus.
    /// </summary>
    public class AzureAwareWorkflowActivity : CodeActivity
    {
        /// <summary>
        /// This method is called when the workflow executes.
        /// </summary>
        /// <param name="executionContext">The data for the event triggering
        /// the workflow.</param>
        protected override void Execute(CodeActivityContext executionContext)
        {
            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();

            IServiceEndpointNotificationService endpointService =
                     executionContext.GetExtension<IServiceEndpointNotificationService>();
            endpointService.Execute(ServiceEndpoint.Get(executionContext), context);
        }

        /// <summary>
        /// Enables the service endpoint to be provided when this activity is added as a 
        /// step in a workflow.
        /// </summary>
        [RequiredArgument]
        [ReferenceTarget("serviceendpoint")]
        [Input("Input id")]
        public InArgument<EntityReference> ServiceEndpoint { get; set; }
    }
}

端点

Endpoint configuration

问题解决了 - 原因是服务主机处理来自CRM的请求的配置不足。

事实证明，从CRM发送的邮件大小超过了允许的范围。添加maxReceivedMessageSize是解决方案（2147483647可以更改为更合理的值）：

<bindings>
  <ws2007HttpRelayBinding>
    <binding name="default" maxReceivedMessageSize="2147483647">
    </binding>
  </ws2007HttpRelayBinding>
</bindings>

服务主机是基于CRM SDK中的Two-way listener example编写的。不幸的是，样本不包含此配置。
