Covers pricing tier requirements (Standard or Premium needed for Topics), how to create Topics and Subscriptions in the Azure Portal, and C# code examples using ServiceBusSender and CreateProcessor to send and receive messages from Topics, using a pizza-ordering example with separate PizzaChef and PizzaOrderInvoices subscriber applications. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between a Queue and a Topic in Azure Service Bus? A Queue removes a message once the first receiver completes processing it, so only one consumer gets each message. A Topic keeps the message available to multiple applications through Subscriptions, removing it from the Topic only after every Subscription has processed its copy. Each subscribing application connects to its own Subscription rather than the Topic directly. _daily.dev surfaces practical messaging architecture guides for developers choosing between queue and pub-sub patterns._ ### Which Azure Service Bus pricing tier do I need to use Topics? Topics require upgrading to the Standard or Premium pricing tier. The Basic tier only supports Queues and prices based on message volume. Standard adds Topics alongside Queues, while Premium adds zone redundancy on top of both, at a higher cost. _Developers planning Azure messaging costs can track tier-specific feature breakdowns like this on daily.dev._ ### How do I send and receive messages from an Azure Service Bus Topic in C#? Sending to a Topic uses the same ServiceBusSender.CreateSender method as a Queue, just passing the Topic name instead. Receiving requires creating a processor with both the Topic name and a Subscription name via CreateProcessor(TopicName, SubscriptionName), since consumers read from a Subscription rather than the Topic directly; the rest of the message-handling code stays unchanged. _daily.dev helps .NET developers find concrete code patterns when wiring up Service Bus consumers._ ## Similar posts on daily.dev - [Coding Azure 20: Backend Processor to Read Storage Queue](https://daily.dev/posts/coding-azure-20-backend-processor-to-read-storage-queue-mo11p9210) · Telerik · 0 upvotes · 0 comments - [Azure Messaging Services: Service Bus vs Event Grid vs Event Hubs — Which One Should You Pick?](https://daily.dev/posts/azure-messaging-services-service-bus-vs-event-grid-vs-event-hubs-which-one-should-you-pick--4oenjkshw) · C\# Corner · 1 upvotes · 0 comments - [Message Queues](https://daily.dev/posts/message-queues-irxnh6uak) · Wawandco · 0 upvotes · 0 comments - [Message Queues: A Simple Guide with Analogies](https://daily.dev/posts/message-queues-a-simple-guide-with-analogies-arcn4kwpp) · Hacker News · 0 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#azure](https://daily.dev/tags/azure), [#.net](https://daily.dev/tags/.net), [#c#](https://daily.dev/tags/c#) [View this post on daily.dev](https://daily.dev/posts/azure-service-bus-queues-vs-topics-k4ibwzl8c) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Azure Service Bus: Queues vs Topics","url":"https://daily.dev/posts/azure-service-bus-queues-vs-topics-k4ibwzl8c","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/azure-service-bus-queues-vs-topics-k4ibwzl8c"},"datePublished":"2026-10-04T13:07:10.086Z","dateModified":"2026-10-04T13:19:32.984Z","description":"A walkthrough comparing Azure Service Bus Queues and Topics, explaining that Topics allow multiple applications to read the same message via Subscriptions,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/67d638a1a83f15ced8841164b40012b0?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/67d638a1a83f15ced8841164b40012b0?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Code4IT","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Code4IT","logo":"https://media.daily.dev/image/upload/s--OaaG4G10--/f_auto,q_auto/v1791119049/logos/code4it?_a=BAMAMicg0","url":"https://daily.dev/sources/code4it"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/azure-service-bus-queues-vs-topics-k4ibwzl8c","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"architecture,azure,.net,c#","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Code4IT","item":"https://daily.dev/sources/code4it"},{"@type":"ListItem","position":3,"name":"Azure Service Bus: Queues vs Topics"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/azure-service-bus-queues-vs-topics-k4ibwzl8c#faq","mainEntity":[{"@type":"Question","name":"What is the difference between a Queue and a Topic in Azure Service Bus?","acceptedAnswer":{"@type":"Answer","text":"A Queue removes a message once the first receiver completes processing it, so only one consumer gets each message.
