Union Types are here in C# 15 and it looks genuinely exciting. For years we've modeled “one of many possible outcomes” using inheritance hierarchies, marker interfaces or lots of defensive checks. Union Types enable exhaustive matching over a closed set of types. Read the blog post devblogs.microsoft.com/dotnet/csharp-… #csharp #dotnet

Seeing all message activity in one place changes how you debug. The All Messages view in the Particular Service Platform makes that possible docs.particular.net/servicepulse/a…

"No way would a 'real' developer be caught dead using 'windows' on their character-mode terminal, no way. It was vi or nothing. Er, sorry, I meant emacs. vim. OK, whatever editor you chose to use, you used that editor, then shelled out to a terminal prompt and built it by hand. I mean with make. I mean.... Gah! Forget the details, just stick with the point, 'real' developers just use the tools we have, because the tools we have are all the tools we will ever need!" 😉 blogs.newardassociates.com/blog/2026/titi…

Businesses can adapt to out-of-order delivery of information so our software should be able to as well. Otherwise pizzas could only be delivered one at a time, and might get cold if the driver got lost on the delivery before you. particular.net/blog/you-dont-…

Idempotency in distributed systems is the property that saves you after the network lies, the queue retries, the client panics, and the operator hits replay. In production systems, duplicate delivery is normal. Duplicate side effects are the bug. dev.to/rosgluk/idempo…

Carl and Richard talk to Dylan Beattie about the Use What Works movement, encouraging developers to use well-maintained open-source projects available today rather than rolling their own. Dylan explains how folks go down a path of believing a library is simple until they learn enough to realize that every bit of software is more complicated than they realize. And the less code you own, the happier and more productive you are. Adding AI to the mix only makes it clearer: you need some stability in development. If you're changing every layer of code, you'll spend even more time and frustration chasing problems. spreaker.com/episode/use-wh…

Sagas are powerful tools, but they're not ALL-powerful. When your process involves an external source of truth, the missing piece is reconciliation. codeopinion.com/why-sagas-feel…

Model Context Protocol (MCP) servers are becoming a key part of how Claude Code extends its capabilities. They give the agent access to documentation, code search, external APIs, and much more. But when Claude Code talks to an MCP server, what exactly is it saying? And what is the server sending back? nestenius.se/ai/visualizing…

If you're interested in the idea of vertical slices and ViewModel composition, you should check out ServiceComposer, which now includes OpenTelemetry support! milestone.topics.it/2026/05/15/ser…

In this video, learn from @adamralph how to turn the remote working dial up to eleven. All you need is a laptop, a camper van, some SIM cards, and a thirst for adventure. particular.net/videos/code-on…

Small code paths become expensive when cloud workloads execute them millions of times. The Azure Event Hubs partition key resolver is one of those paths. By removing temporary allocations from the partition-key encoding path, the Azure Event Hubs SDK reduced garbage collection pressure on a publishing hot path. planetgeek.ch/2026/05/15/sma…

IBM MQ is point-to-point. Pub/sub is a manual wiring job on the queue manager. There's no "publish an event and let subscribers handle it" model in the native client. Topic objects and durable subscriptions have to be configured explicitly on the queue manager. Every new subscriber is another manual step. In large environments, monitoring and replaying failed messages also lacks built-in tooling. Teams build scripts. Then scripts to manage the scripts.

Shouldn't it be easier than that? It can be: docs.particular.net/transports/ibm…

In a web application, you probably just want to send NServiceBus messages without processing any or maintaining a queue. This sample will show you how to get that set up in an #AspNetCore WebAPI application. docs.particular.net/samples/web/as…

Whether you are a seasoned architect or a developer just starting to explore DDD, understanding how to communicate between different parts of your system via events is a superpower. blog.nimblepros.com/blogs/domain-e…

If web development is your thing, here's one for the calendar. @csharpfritz is teaching a hands-on livestream workshop on modern web development. Practical, current, worth your time. We're proud to support it. gapvelocity.ai/web-developmen…

We've released a new version of our Azure Service Bus transport that supports dead-lettering and DLQ auto-forwarding among other improvements. discuss.particular.net/t/nservicebus-…

"We need to embrace the idea that some failures are inevitable. It's too expensive to try to prevent them completely. Instead we should focus on making sure we can detect issues quickly and compensate for them when they arise." particular.net/blog/what-star…

A useful reminder from Milan Jovanović: primary constructor parameters are captured as mutable variables, not readonly fields. The compiler will not stop you from reassigning them. In service classes that is rarely a real bug; in entities it can be. milanjovanovic.tech/blog/why-i-swi…

NServiceBus allows you to focus on the domain logic and not the infrastructure code required to deserialize messages and invoke your business code on AWS Lambda. docs.particular.net/samples/aws/la…

@lovelacecoding Awwwww 😊

@ParticularSW Amazing team 🤩

All good things must come to an end and so does our time at #TechoramaBE. A big thank you to the event organizers, sponsors and the attendees. Thank you for the great talks, wonderful conversations and learnings. See you all at #TechoramaNL in October.
