Exposing WSDL on BasicHttpRelayBinding over Azure

阅读更多关于 Exposing WSDL on BasicHttpRelayBinding over Azure

问题 I have an svc that is auto-started using AppFabric. What I want to do is expose the wsdl for my service over the bus. Internally the service and the wsdl work fine of course, I can also consume the service over the bus with no issue. The only thing I can't configure properly is viewing the wsdl over the relay. The ServiceHostFactory creates default endpoints and also adds an Azure Endpoint along with a mex endpoint in hopes to expose the wsdl over the relay. When I try to view the wsdl from

问题 I have been using Azure Storage Queues to feed a WebJob, using the QueueTrigger attribute. I configure my QueueTrigger to dequeue a number of items for concurrent processing, like this: public static void Main() { JobHostConfiguration config = new JobHostConfiguration(); config.NameResolver = new QueueNameResolver(); config.Queues.NewBatchThreshold = 10; JobHost host = new JobHost(config); host.RunAndBlock(); } public static void ExecuteStorageQueueItem([QueueTrigger("%AzureQueueName%")]

Why not always configure for max number of event hub partitions?

阅读更多关于 Why not always configure for max number of event hub partitions?

问题 The Azure Event Hubs overview article states the following: The number of partitions is specified at the Event Hub creation time and must be between 8 and 32. Partitions are a data organization mechanism and are more related to the degree of downstream parallelism required in consuming applications than to Event Hubs throughput. This makes the choice of the number of partitions in an Event Hub directly related to the number of concurrent readers you expect to have. After Event Hub creation,

阅读更多关于 Exceeds the limit (262144 bytes) currently allowed on the link Exception on SendBatch() method of Azure service bus SDK

We are using SendBatch() method of Azure service bus SDK 3.1.7 to send data to Azure Event Hub. Following is the code snippet : foreach (var packet in transformedPackets) { EventData eventData = new EventData(Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(packet, settings)));; try { eventData.Properties.Add(AppConstants.TenantDeploymentUniqueIdKey, tenantDeploymentUniqueId); eventData.Properties.Add(AppConstants.DataTypeKey, DataTypeKey); byteCount += eventData.SerializedSizeInBytes; if (byteCount > MaxBatchSize) { sender.SendBatch(transformedMessages); transformedMessages.Clear();

阅读更多关于 azure notification hubs - app uninstall

I would like to use Azure Notification Hubs to send push notifications to users of my app running across iOS, Android and Windows Phone. I have managed to get the basics working but I don't know how to manage the App uninstall story. On starting, the mobile app will call my Identity Svc to get an Auth Token. It then calls its Platform Notification service (eg Google Cloud Messaging, APNS) to get a PNS Token. After persisting the token to local storage it will call a back-end Contact Svc to register the customer's device. This service will create a subscription to the Azure Notification hub for
