We’re here! 👋 The Particular Software booth is up and running at #TechoramaNL. If you're building message-driven systems - or wondering why yours behaved perfectly in development and then did something *interesting* in production - come talk to us. 😄

consistency complicating compensation, and integration tests trying to cover every boundary. Most come from tooling and misapplied concepts, not events themselves.

🔄 Change is inevitable. Breaking everything isn’t! Learn practical techniques to evolve event-driven systems, version message contracts and maintain compatibility without downtime. 🚀 📅 Nov 17 · Thomas More Campus De Nayer 🎟️ www.visug.be/events/2026-... #VisugXL #dotnet #Architecture

But I assure you if you haven’t been you will absolutely regret not making it to this years TechoramaNL which is featuring and over the top medieval theme that is NOT TO BE MISSED

Hey #NDCOslo! 👋 Meet the engineers behind Particular Software! @SzymonPobiega @PoornimaNayar @Masternak and Andreas are here. Building a #distributedsystems? Bring your architecture questions. We'd love to talk messaging, event-driven systems, reliability, and real-world trade-offs. #dotnet

One topic, many subscriptions in Azure Service Bus. A shared topic can be a good trade-off. But filters, fan-out, and storage work accumulate there, and topic depth shows when delivery falls behind. www.planetgeek.ch/2026/08/14/a... #AzureServiceBus #NServiceBus

We built our previous Azure Functions integration based on the foundations of the past, where only one endpoint is feasible and runtime assembly scanning is inescapable. The new Azure Functions model allows multiple endpoints to coexist in a single Functions App.

All together, a great set of tools for situations where speed is important, and message durability either isn't necessary or can be "reloaded" after a process restart.

Modeling business requirements and policies is a tricky thing. In this video, @indualagarsamy discusses the saga message pattern to see how you can model complex business workflows, and model time as an immutable durable event

Another thing that’s sticking with me is the importance of social learning and peer support. I think I can credit a lot of my success, especially earlier in my career, to landing in an organization that values collaboration, information sharing, and mentorship.

Aspire support in NServiceBus continues to get better and better...

Most engineers undervalue their time. You have more important work to do than re-inventing the wheel.

I have to say, that's quite the wall of names for something that's been out less than a week. It's encouraging to see so many people showing their support for what we're trying to do here. Want to join us? Head over to usewhatworks.org and sign the manifesto.

🎙️ @oldbooksmell.bsky.social is speaking at #StirTrek2026! "Microservices for Pragmatists" and "Boiling The Frog: Implementing a Modern Message Based Architecture Without Anyone Noticing" 📅 1 May 2026 🎟️ events.humanitix.com/stir-trek-20... We're really looking forward to having Hazel this year!

Don't miss our live webinar in less than 48 hours! Even if you can’t make it live, register, and we’ll send you the recording when it’s available. Effortless Distributed Systems with Aspire, with @jasontaylordev

"Obvious" if you've been around a while, but still needs broader awareness: > New tech typically has more known unknowns, and many more unknown unknowns > software that’s been around longer tends to need less care and feeding than software that just came out #UseWhatWorks boringtechnology.club

There’s no single “best” way to version APIs. Each strategy exists because it solves a different problem. The key is matching the strategy to your context.

How do you design a UI when the back-end system consists of dozens (or more) of microservices? In this video, Mauro Servienti shows how to use the concept of UI Composition to build a page without losing autonomy between services

If implicit ranking can silence a room of senior engineers during a training simulation, imagine what it is doing to your actual architecture design sessions. If we don't actively facilitate group dynamics and level the playing field, we lose the vital perspectives required to solve complex problems

This thread demonstrates how people may *think* they are representing the "problem space" when they are still subconsciously stuck in the "solution space". My recommendation is to delay naming things, using placeholders like colors in the interim - uncomfortable at first, yes, but helpful. Try it.

Yup, many people underestimate the "gravity" of data when doing legacy modernization. That and data quality issues.

With more and more open source projects switching to some sort of commercial licensing model with discounts for small business and community projects, the question keeps coming up: is a 100% discount the same as "free"? So I made a video about it. What do you think? www.youtube.com/watch?v=CpI8...

.NET 10 is out! Before you ask, you can already use .NET 10 in your #NServiceBus endpoints. We've run tests with the previews along the way to ensure you won't run into any issues when you change your target framework.

💻 Build cross-language integrations with ease! Watch the demo of a .NET producer and Python consumer using RabbitMQ transport with NServiceBus. ➡️ https://youtube.com/live/YWHY09R46m4 #RabbitMQ #Integration #NServiceBus #Microservices

Today at 1530 Eastern Time, I'll be talking about Clean Architecture with ASP.NET Core 10. Check it out, I have some new stuff to share. dotnetconf.com #dotnet

This talk is a must-watch for people in the Event-Driven space. I saw @noctovis.bsky.social giving it live at this year's DDDEU, and I truly believe that she nailed the versioning topic 👇🙂 www.youtube.com/watch?v=6TCb...

Companies don’t realize their developers often make decisions without leadership involved (to build their own infrastructure because it’s fun) that then burden the company with supporting such systems indefinitely. At the expense of a simpler more maintainable app.

"Rants and Raves" from @wildermuth.com > I think this is true whether it is an open source project, or a commercial product. It has felt like developers can get focused on “How hard could it be?”.

NSB now completely *free* for orgs under $1M ! PLUS significant discounts as you grow to $5M !! particular.net/blog/launchi...

🎉 Please join us in congratulating Irina Dominte (Scurtu) @irina.codes on being elected to the .NET Foundation Board of Directors! We look forward to your leadership and impact in the .NET community. 💫 #dotnetfoundation

Old but seems still relevant udidahan.com/2010/08/31/r.... Crazy how quickly everything changes in software :P

New in NServiceBus! Now you can use #CloudflareR2 to store large message bodies in #AmazonSQS systems, which may be more cost effective for your system.

A lot of really cool AWS .NET enhancements for NServiceBus. I especially appreciate the support for our Lambda Annotations framework. particular.net/blog/aws-enh...

New on the blog! We released a bunch of enhancements to our AWS-related components, including improvements to the #SQS transport, #DynamoDB persistence, and #Lambda hosting. Check out all the details here.

We can fall into a trap, believing things happen synchronously in a predefined order. They don't–at least not in scalable systems, and certainly not at Starbucks. "What Starbucks can teach you about (software) scalability" on our blog:

When you're trying to set culture, you need to prioritize high-trust environments and the delivery of feedback. You cannot let yourself be "casually cruel in the name of being honest" even just a little bit or trust and culture will degrade. - @rstephens.me @ #monktoberfest

Schemas are a great way to make versioning event-driven systems easier, and @ApacheAvro has the best schema evolution capabilities out there. And, you can use Avro with @NServiceBus too! Check out the samples: https://docs.particular.net/shape-the-future/avro #avro #schemaevolution #eda #serdes

And I draw on Mary Parker Follett’s work; it’s from ~100 years ago, but not only deserves a place in the formative history of the system design (and leadership) field, but in the discourse that helps shape our understanding and approaches today.

In this video, @mauroservienti analyzes the most common errors in building a (micro)services-based architecture. How do we avoid the hype and design systems with longevity as the primary goal?
