Event-driven integration - Overview [ASPF02O|E039]
In this episode, we take a look at the integration problem we have between services right now, go through some options to avoid or fix it, then have a quick overview of the solution we'll be implementing in the coming episodes.

More explicit domain error handling and fewer exceptions with Either and Error types [ASPF02O|E038]
Following up on the last episode about the Optional type, we continue taking inspiration from functional languages and introduce Either and Error types, as a way to make the possible business logic outcomes more explicit and minimize using exceptions in non-exceptional situations.

Better use of types - avoiding nulls with an Optional type [ASPF02O|E037]
In this post, we'll make use of a concept most commonly associated with functional programming, the Optional type (aka Option or Maybe), in order to make our code safer and more explicit when expressing a lack of value, instead of leaning on the null reference, something that I'm sure has burned us many times in the past.

E036 - Making things more object oriented with rich domain entities - ASPF02O
In this episode, we'll make things more object oriented, by moving some logic that's present in the request handlers, which in fact should be present in the domain entities, that currently are just bags of data with public getters and setters.

E035 - Experimenting with (yet) another approach to data access organization - ASPF02O
In this episode, we'll take a look at (yet) another approach to organizing data access code, very likely overkill.

E034 - Segregating use cases with MediatR - ASPF02O
In this episode, we'll take a look at segregating our application use cases in dedicated classes instead of shoving everything into the same service class.

E033 - Redesigning the API: Improving the internal architecture - ASPF02O
In this episode, we'll take a look at redesigning an API that has been developed in a traditional layered way, moving to a more interesting onion/hexagonal/ports and adapters architecture (which is apparently very fashionable right now in .NET land).

Use POCOs to group data and logic - there's more to life than services and DTOs
In C# land, the abuse of services and DTOs is prevalent. How about grouping data and behavior using POCOs? You know, ob)ect oriented stuff 🙂.

"Equals" and "==" are not... equal
"Equals" vs "==" is an old topic, but as it's often times forgotten, there's probably no harm in talking about it again.
