Microservice Architecture in ASP.NET Core

Microservices are easy—until they need to communicate reliably. Join Roland Guijt on Pluralsight to learn how to build resilient microservices with NServiceBus, covering messaging, workflows, and the patterns real distributed systems depend on.

Fallacy #5: Topology doesn't change It’s easy for something that started out simply to become much more complicated as time wears on. I once had a client who started out with a very noncomplex server infrastructure. The hosting provider…

"It would be foolish to try implementing a service discovery scheme on your own when good options already exist, unless service discovery is specifically your business domain." The 5th Fallacy: Topology doesn't change, on our blog:

The Sinking Ship: Protecting .NET Microservices with the Bulkhead Pattern A practical guide to isolating resources and preventing cascading failures in distributed systems using Polly.

When one microservice fails, does everything fail? It shouldn’t. The Bulkhead pattern isolates failures so one problem doesn’t sink your entire system. A great .NET resilience pattern worth understanding.

24x7 support for critical message-driven applications

It's 2am and messages won't process. Where are you going to turn? Get 24x7 critical support (even for MassTransit/Rebus/Brighter systems) with 5-hour or even 1-hour response SLA from the experts at Particular Software for as little as $1000 per month.

Flow Diagram • ServicePulse Describes how ServicePulse illustrates the flow of a message and its related messages within the same conversation.

When a workflow becomes complex, it is easy to lose track of how messages actually move through each step. The Particular Service Platform flow diagram brings that movement into focus.

Messaging in .NET: Queues, Topics, and Why You Need Them Learn why asynchronous messaging matters in .NET applications, how queues and topics differ, and when to use RabbitMQ, Azure Service Bus, or AWS SQS to ...

Synchronous calls optimize for simplicity. Messaging optimizes for reality. If you're building distributed systems in .NET, understanding queues, topics, and async communication is essential.

Validating configuration at startup with IValidateOptions in .NET When you build .NET applications with strongly typed configuration, IOptions<T> and its variants give you a clean way to bind appsettings.j...

A missing config value won't stop your .NET service from starting. It'll silently break at 2 AM in production. IValidateOptions<T> with ValidateOnStart() prevents this: your service won't start with bad config, and the validator has full DI access for cross property checks. By Bart Wullems.

Lease Pattern in .NET: A Lock With an Expiration Date That Saves Your Data - Chris Woody Woodruff | Fractional Architect Indefinite locks belong to a world where processes never crash and networks never split. That world does not exist. In a distributed system, “I hold the lock” can mean “I held the lock before my VM paused for 45 seconds.” A lease fixes that by putting a deadline on ownership and forcing the owner to

When a process crashes while holding a lock, what happens to the resource? Most teams don't find out until production teaches them. Chris Woodruff explores why indefinite locks are a liability in distributed systems and what to reach for instead.

Your Database Can't Read. Vector Databases Can. Learn how vector databases work, what embeddings are, and when to use Qdrant, Weaviate, Pinecone, or pgvector in your .NET stack.

Does your search need to understand meaning or just match exact text? That distinction is the core of what vector databases solve, and it's simpler than most explanations make it sound. Great walkthrough from @irina_scurtu.

What Your .NET Exceptions Are Telling Attackers (And How to Stop It) Unhandled exceptions in .NET APIs expose stack traces, database schemas, and internal paths to anyone watching. Learn how to implement secure error hand...

Exceptions are a security boundary, not just a reliability concern. Your logs should have everything; your clients should have nothing they didn't need to know. Correlation IDs bridge the gap. Practical guide by Adrian Bailador.

Coding Isn’t the Hard Part Coding isn't the hard part because of AI and coding agents, is what I keep reading. However, it was never the hard part to begin with.

Most enterprise systems aren't algorithmically complex. They're workflow complex. Yet teams pour energy into implementation details instead of the much harder question: what exactly should we be building? @CodeOpinion explores why that matters.

Is Event-Driven Architecture Overkill for Most Apps? Event-Driven Architecture can seem overkill if you don't really understand the purpose. It's about decoupling responsibility in time.

Events as notifications vs. event sourcing vs. async messaging. Teams treat these as the same thing all the time, and that's where architectural mistakes start. Derek Comartin @codeopinion explores why these keep getting conflated.
