What is the clean architecture and how you would build one in .NET? Recently Bob Martin has categorized a set of architectures, including hexagonal architecture, onion architecture and screaming architecture as 'the clean architecture' - a layered architecture of concentric circles with a strong emphasis on separation of concerns. This architecture has become popular because of its amenability to modification as an evolutionary architecture and its support for practices such as TDD. In this presentation we will discuss the clean architecture and its benefits. More than that, in the bulk of the presentation, we will show you how to implement a clean architecture in .NET. From first steps to working code, we will show you the moves required to embrace this approach, and introduce you to some of the OSS libraries that can help you get there. All examples will be in .NET Core

There are few like Ian who can make everything so clear. Got to see him in NDC Porto 2023. Always excellent.

this is the best talk on clean architecture. I hv been trying to gather more Clean Architecture. Went thru few on NDC Conf, Goto, Steve Smith and others. They r good. However, this is the real deal with covers everything. I really appreciate the effort coz every sentence is essential. I loved when presenter said do we cover use cases using code and is it visible to devs. Thanks you for this

The trouble I always find with code samples like at the end in talks like these is, that for those small demo's the original is in many cases easier to work with and understand, it's only when you get into a much larger system that it gets more useful. Unfortunately many people just see that end bit and say well it just shows this approach is not good. I'm not saying I do that, I actually believe a layered approach is the best way to go, however I know many people that think it's awful, and I think the samples they see are awful which doesn't help.

There is that saying about standing on the shoulders of giants and developers are stepping on their own toes.

In reality, the world is much more complex. Business people tells developers to add their (unorganized) ideas and change requirements any second. Developers don't have political power to make code clean. They struggle to meet deadlines, non-devs don't read the code and don't give time to resolve tech debts. New devs join the company and complain that code is dirty. This happens like 99% percent of time. The people who preach scrum, tdd, clean architecture, etc. are coaches who make money by lecturing. They make money by telling developers that they are doing everything wrong as if they are some kind of authority.

@@sea0920in reality more people then coaches preach those things, I infact preach many of them because over the years I have seen success using them. If devs aren't empowered within your organisation I would say quit and move else where, while business people come down with requirements devs define how the code works and looks, devs should feel empowered to push back against requirements. Sure a junior might struggle to feel empowered, but senior and principal devs should be able to influence and drive technical direction.

This is the best description of clean/hex that I've found. I'm glad he touches on testing and explains to primarily test input ports. I am not sure it's right to say controllers are interactors. The problem is that some controllers are bound to frameworks. I think it's more accurate to say that controllers should be thin pass-through objects that relay UI data directly to/from the interactors. That the interactor are the control logic and controllers are the adaptors.

That camera is in need of a clean architecture. Thankfully the cam didn't attempt to give a fuller picture of the presenters nose openings, like a Python cam.

Why is Clean Arch so popular among the C# community but not in the Java?

I think it might be connected to the fact that c# is used for creating games. Games are performance hungry

It's not really correct to have a infra dependency in the domain layer. If it is for domain events than it should probably move to a shared kernel layer.

I can't imagine trying to explain all these abstractions to junior devs and maintaining any kind of long term fidelity to it. No doubt it would become an unmitigated mess. And senior devs would just argue about it. Of course not doing this results in an unmitigated mess as well so I don't know. I guess I'd prefer my messes with fewer abstractions

I doesn't have to be the extremes - either not structure or the complete full blown structure (shown in the presentation). Be pragmatic and use what helps and avoid the rest. If you want to see a pragmatic example in java, checkout the coding kata from Sandro Mancusos that you can find here kzbin.info/www/bejne/jnnRpoCgls1pptU (this the first of three parts).

Having worked with this in large codebases I can say with confidence: it's nice in theory but awful in practice. The devil is in the details and people will abuse "interactors" in every possible way. Soon you'll have one interactor calling 5 other interactors which in turn call other interactors and in the end all you have is a procedural nightmare. Unless you're strict about everything under this architecture, it will surely make your code unnecessarily complex with very little benefit. Be very careful with this.
