The best part, there's nothing mystical or complicated about Clean Architecture - it is a relatively simple and practical architecture template that can be applied to many application domains if you choose to follow just a few of its basic rules. "I've changed my routine, now I'm clean "

Broadly sensible article but doesn't address the problem that can arise if your database has any logic in it at all (even constraints but certainly views or sprocs) in that you then have two architectures sharing the responsibility for business functionality.

Personally, this doesn't go far enough by a long shot. Unless I missed something, there's no guidance on how to avoid entanglement within each layer, and there's no guidance on how to move data between layers (more entanglement.) The IRequest and IRequestHandler seem to be moving in the right directly, but I would not have hidden that so well -- it took me a couple scans to even see that.
One key aspect of the request/response messages that flow in and out of use case interactors and across boundaries is that they are simple data structures meaning they contain no special types: ie. entities, or types provided by 3rd party libs etc. - they are pure C# objects.
That's such a bizarre statement. Even types provided by 3rd party libs are probably pure C# objects. What's the guidance here? How does this messaging system work? If you're doing direct calls between layers through those two interfaces, you're still entangling code, even if it looks prettier because you're using an interface.
Looking at the original documentation regarding crossing boundaries:
The important thing is that isolated, simple, data structures are passed across the boundaries. We don’t want to cheat and pass Entities or Database rows.
OK, sure, database rows, yeah, I get that. But entities? Why the hell not? Should I create completely separate "non-entity" classes and the serialization/deserialization simply to publish them on an outer layer? That seems silly.
And it makes no sense, given:
So when we pass data across a boundary, it is always in the form that is most convenient for the inner circle.
But I would argue that putting the DB in the outer layer is an arbitrary choice. In fact, putting entities in the inner layer is an arbitrary and not always correct choice.
As I concluded a long time ago, a bullseye circle layer for representing an architecture is actually the totally wrong approach. But that's me, and I'm probably missing something.

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I have always enjoyed reading the The CodeProject Insider Daily Developer News newsletter but for some reason I am not receiving them for the last 3 days. A friend of mine has not received his either. Has this newsletter been discontinued? If not how do I tell your site to send me the last 3 days of newsletters? Thanks... John
P.S. I am sorry if this is not the right forum but I could not see a better place to post the question.

You can thank the Canadian government[^].
All Canadian subscribers who have not explicitly opted in for newsletters are no longer able to get newsletters anymore. By explicitly the government means "The recipient gave a positive or explicit indication of consent to receive commercial electronic messages". In particular companies based in Canada that send out emails cannot pre-check[^] a "sure, send me your newsletters" checkbox. ie standard practice everywhere on the web except Canada.
It's also retroactive, meaning that those that signed up pre 1 July, 2014 can no longer be considered to have provided consent.
Over the weekend I'm going to add a button with an unchecked checkbox for our Canadian readers to check in order to explicitly say "sure, send me the newsletters". Until then you should be able to go to your profile, uncheck a newsletter, hit save, then recheck it and save and you've provided "explicit consent" and we can send emails again.
The purpose of all of this? To make a point that the government of Canada is cracking down hard on spammers. Except it hasn't actually made a dent in the amount of spam we get in Canada. It's our version of the "this site uses cookies" warning silliness.
(sorry if I seem jaded and exhausted by all of this but it's been a bit of a busy week trying to deal with the Canadian government)

With that, and several other recent news stories from there, I say Canada is going due South at around the speed of sound.
