C# 15 is getting union types.

That’s a big deal.

It means patterns like Result and Option finally have real language support.

No more awkward wrappers.
No more hacks.
No more pretending exceptions are the best way to model failure.

I’ve advocated for the Result pattern for years, but lack of native support always made it clunky.

That changes with union types.

Don’t want to wait?

Here’s how to implement the Result pattern today: https://t.co/NtKei20pBR

If you still prefer throwing exceptions, you can skip this.

CQRS != MediatR.

Stop conflating CQRS with MediatR.

Just because you're using MediatR doesn't mean you're doing CQRS.

CQRS is about separating reads from writes, often using different models, persistence strategies, and sometimes different data stores.

MediatR, on the other hand, is a library for in-process message dispatching. It’s great for organizing commands and queries, but it’s not a CQRS framework.

You can use MediatR in a CQRS-style architecture.
But don’t assume one implies the other.

Understand the distinction before you adopt the pattern or the tool.

Do you separate your read and write models in practice?

Processing the same message twice is a nightmare in distributed systems.

If you are not careful, one event could trigger duplicate side effects and corrupt your data.

My strict rule for microservices: Every single consumer must be idempotent.

You have two ways to achieve this:

1. Make the business logic naturally idempotent.
2. Build an Idempotent Consumer.

Here is the exact flow for the Idempotent Consumer pattern:

• Check your database for the incoming message ID.
• If it exists, skip processing.
• If it is new, process the event and save the message ID.
• Wrap these steps in a single database transaction.

If you want to see the C# code, I wrote a complete guide on implementing this in .NET. It also covers the Inbox pattern for even better reliability.

Protect your data from duplicate processing before it hits production.

SOLID Principles Explained with Clear Examples:

𝐒 - 𝐒𝐢𝐧𝐠𝐥𝐞 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐢𝐛𝐢𝐥𝐢𝐭𝐲 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞
A class should have only one reason to change.
- Example: Instead of one giant User class that handles authentication, profile updates, and sending emails, split it into UserAuth, UserProfile, and EmailService.

𝐎 - 𝐎𝐩𝐞𝐧/𝐂𝐥𝐨𝐬𝐞𝐝 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞
Classes should be open for extension but closed for modification.
- Example: Define a Shape interface with an area() method. When you need a new shape, just add a Circle or Triangle class that implements it.

𝐋 - 𝐋𝐢𝐬𝐤𝐨𝐯 𝐒𝐮𝐛𝐬𝐭𝐢𝐭𝐮𝐭𝐢𝐨𝐧 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞
Subtypes must be substitutable for their base types without breaking behavior.
- Example: If Bird has a fly() method, then Eagle and Sparrow should both work anywhere a Bird is expected.

𝐈 - 𝐈𝐧𝐭𝐞𝐫𝐟𝐚𝐜𝐞 𝐒𝐞𝐠𝐫𝐞𝐠𝐚𝐭𝐢𝐨𝐧 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞
Don't force classes to implement interfaces they don't use.
- Example: Instead of one fat Machine interface with print(), scan(), and fax(), break it into Printable, Scannable, and Faxable. A SimplePrinter only implements Printable.

𝐃 - 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐲 𝐈𝐧𝐯𝐞𝐫𝐬𝐢𝐨𝐧 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞
High-level modules should not depend on low-level modules. Both should depend on abstractions.
- Example: Your OrderService should depend on a PaymentGateway interface, not directly on Stripe or PayPal.

The real power of SOLID is not in following each principle in isolation. It's in how they work together to make your code easier to change, test, and extend.

You probably don't need a Dockerfile anymore.

If you're building .NET apps, the SDK can generate optimized container images natively.

✅ Just: dotnet publish /t:PublishContainer

[Milan Jovanović @mjovanovictech]

Your software architecture isn't worth much if it's easy to break.

I'll show you a better approach.

I use these 3 approaches to help my team stick to the design:
- Compiler, static analysis
- Architecture testing
- Code reviews

The compiler is your best friend. It will never let you make a mistake. If you write code that doesn't compile, your build will crash, which is awesome.

But how can we use this to enforce software architecture?

Our options in .NET are limited. But you can use the internal access modifier to hide types from other assemblies. You can also organize your code into separate projects (assemblies) to enforce isolation.

Unfortunately, this doesn't scale well because you end up with many projects.

Static analysis is interesting, but I don't like writing custom Roslyn rules.

Instead, I prefer architecture testing.

Architecture tests let me express my design rules as automated tests. I can use them to enforce the correct direction of dependencies.

This is valuable in a modular monolith.

For example, each module can only reference the public API of other modules.

Lastly, we have code reviews.

This should be self-explanatory. Someone has to review the code and approve it manually.

So, which approach should you use?

I put more effort into making use of the compiler and architecture testing.

Here's how architecture testing can help you "shift left": https://t.co/dY3lAfecmI

Even the most well-planned software projects decay because of technical debt.

Most developers have good intentions. However, time pressure, misunderstandings, and resistance to rules all contribute to this problem.

Architecture testing acts as a safeguard.
