Read it at the original source: ## Questions this post answers ### How do I implement the request-response pattern in MassTransit with .NET? Define a request and response record, create a consumer implementing IConsumer that calls context.RespondAsync with the response type, register the consumer with AddConsumer, register a client with AddRequestClient(), then inject IRequestClient and call GetResponse to send the request and await the typed response. _Developers wiring up request-response messaging can browse implementation walkthroughs like this on daily.dev._ ### What message transports does MassTransit support in .NET? MassTransit provides a unified messaging abstraction across RabbitMQ, Azure Service Bus, Amazon SQS, Kafka, and an in-memory transport. The in-memory option is useful for development but lacks durability and distributed capability, since it only works within a single application instance and loses queued messages on restart or crash. _Teams comparing message broker options for distributed .NET systems can track trade-offs like these on daily.dev._ ## Similar posts on daily.dev - [The Mediator pattern with MassTransit](https://daily.dev/posts/the-mediator-pattern-with-masstransit-juyjfnbh0) · The Art of Simplicity · 15 upvotes · 1 comments - [Event-Driven Architecture in .NET Core Using RabbitMQ](https://daily.dev/posts/event-driven-architecture-in-net-core-using-rabbitmq-btcsrhdsv) · C\# Corner · 21 upvotes · 0 comments - [Getting Started With NATS JetStream in .NET](https://daily.dev/posts/getting-started-with-nats-jetstream-in-net-6r74llqr0) · Milan Jovanović · 16 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#.net](https://daily.dev/tags/.net), [#distributed-systems](https://daily.dev/tags/distributed-systems), [#rabbitmq](https://daily.dev/tags/rabbitmq) [View this post on daily.dev](https://daily.dev/posts/pub-sub-and-request-response-patterns-with-masstransit-7jk0wea2n) ```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":"Pub/Sub and Request-Response Patterns with MassTransit","url":"https://daily.dev/posts/pub-sub-and-request-response-patterns-with-masstransit-7jk0wea2n","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/pub-sub-and-request-response-patterns-with-masstransit-7jk0wea2n"},"datePublished":"2026-10-04T13:07:02.619Z","dateModified":"2026-10-04T13:12:10.338Z","description":"A step-by-step walkthrough of implementing publish/subscribe and request/response messaging patterns in .NET using MassTransit, covering setup with in-memory...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/53c528dedd0dc5f6725bf19b3be0c061?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/53c528dedd0dc5f6725bf19b3be0c061?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"NikolaTech","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":"NikolaTech","logo":"https://media.daily.dev/image/upload/s--1h2fO6FL--/f_auto,q_auto/v1791119050/logos/nikolatech?_a=BAMAMicg0","url":"https://daily.dev/sources/nikolatech"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/pub-sub-and-request-response-patterns-with-masstransit-7jk0wea2n","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"architecture,.net,distributed-systems,rabbitmq","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"NikolaTech","item":"https://daily.dev/sources/nikolatech"},{"@type":"ListItem","position":3,"name":"Pub/Sub and Request-Response Patterns with MassTransit"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/pub-sub-and-request-response-patterns-with-masstransit-7jk0wea2n#faq","mainEntity":[{"@type":"Question","name":"How do I implement the request-response pattern in MassTransit with .NET?","acceptedAnswer":{"@type":"Answer","text":"Define a request and response record, create a consumer implementing IConsumer that calls context.RespondAsync with the response type, register the consumer with AddConsumer, register a client with AddRequestClient(), then inject IRequestClient and call GetResponse to send the request and await the typed response.
