Azure Service Bus .NET SDK Deep Dive – Scheduling

A

Explains scheduling of messages into the future, for more posts in this series go to Contents. What if we could write a letter to our future self? It turns out with Azure Service Bus we can! With the SDK, it is possible to schedule a message to be due at a certain point in time, and the broker will make sure to deliver it back into the queue when the date is due. With that trick, we can store durable timeouts on the broker to kill our batch jobs or implement things like invoice reminders. var...

Azure Service Bus .NET SDK Deep Dive – Connections

A

Explains connections and how they relate to senders and receivers, for more posts in this series go to Contents. So far, we’ve been creating QueueClients to send and receive messages. We’ve also learned that we can leverage MessageSenders and MessageReceivers to abstract our code slightly from the actual entity in use. The below code illustrates a small example that sends a message to a destination and then receives a single message from that destination. var sender = new...

Azure Service Bus .NET SDK Deep Dive – Sender, receiver and abstractions

A

Explains senders, receivers and the abstract types, for more posts in this series go to Contents. So far we have been using QueueClient both for sending messages to a queue as well as receiving messages from a queue. The Azure Service Bus SDK has multiple concrete types that allow to operate with a specific entity. The QueueClient allows to interact with the abilities of a queue. If we want to leverage code that interacts with topics (more about those later) we can create a TopicClient. For...

Azure Service Bus .NET SDK Deep Dive – Receiving a message

A

Explains receiving a message from a queue, for more posts in this series go to Contents. In the previous post I showed the basic bits to send a message into a queue. But how can we get it out again? The good news is that the SDK makes it pretty simple to fetch a message from a queue. We can register a message handler delegate on the queue client. The delegate is automatically called when a message arrives in the queue we are listening to. client.RegisterMessageHandler( async (message, token) =>...

Azure Service Bus .NET SDK Deep Dive – Sending a message

A

Explains send a message to a queue, for more posts in this series go to Contents. In the previous post we looked at how queues can be created with the management client. For being able to send messages to queues we required the Microsoft.Azure.ServiceBus package. If you search for Azure Service Bus on nuget you might stumble over the WindowsAzure.ServiceBus package, be aware that this is the old and new legacy Azure Service Bus client. For any new development you want to use the Microsoft.Azure...

Azure Service Bus .NET SDK Deep Dive – Creating queues

A

Explains how to create queues with the management client, for more posts in this series go to Contents. Without queues, topics and subscriptions (also called entities) there is not much we can do with an Azure Service Bus namespace. For the start it is sufficient enough to create a queue that we will use to send messages to and receive messages from. Creating entities requires a reference to the Microsoft.Azure.Management.ServiceBus package. In contrast to the older (new legacy Azure Service...

Azure Service Bus TopologiesAzure Service Bus Topologies with ForwardingAzure Service Bus Topologies of NServiceBusAzure Service Bus Topology migration with NServiceBus (current) In the last post I explained the complexity we introduced for our customers when we created multiple topologies without providing a smooth migration path. In this post I’ll walk you through the online migration path that we created to allow our customers to transition their existing NServiceBus endpoints using...

Azure Service Bus TopologiesAzure Service Bus Topologies with ForwardingAzure Service Bus Topologies of NServiceBus (current)Azure Service Bus Topology migration with NServiceBus (next) Almost a decade ago Particular Software started supporting customers running on Azure Service Bus by leveraging a robust and reliable queue abstraction called NServiceBus. Particular Software has been one of the early adopters of the PaaS Service. Hundreds of customers later we can look back at many scars and...

Azure Service Bus Topologies with Forwarding

A

In the previous blog post, I introduced topologies for Azure Service Bus and how topics and subscriptions can be leveraged to build reliable publish and subscribe infrastructure. All the approaches described in the last post have one major drawback: Subscriptions need to be managed for all events the subscriber wants to subscribe to. Wouldn't it be nice if we could automatically enqueue all messages in the input queue of the subscriber without having to manage receiving infrastructure for all...
