Using the object capability security model in C# CRUD applications

This post shows an example about how object capabilities can be used in a CRUD application to defer authorization to individual models.

How to effectively observe the runtime behaviour of your core domain

Logging statements have no place in the domain. There are multiple better alternatives you should use instead!

What is Event Sourcing?

This post attempts to explain event sourcing through examples showing what it is and what it is not, while highlighting some of the strengths and reasons for using it.

What makes an event sourced domain?

In an effort to generalize event sourcing to the whole domain I try to adapt concepts previously developed for aggregates to other domain objects such as services, process managers, sagas and repositories.

More transparent command to event transformation

An improvement upon the previously proposed event sourced aggregate where command provides type information about its returned domain events.

Coarse commands emitting granular events

In order to allow an event sourced software system to evolve I believe it to be important to issue coarse commands emitting granular events. In this post I explain why.

Can I map one command to multiple events?

Since it would be beneficial for commands to be able to issue multiple events reflecting its behaviour I modified an earlier approach to event sourced aggregates to allow this use-case.

Creating event sourced aggregates with C#

The aggregate is a well understood concept within DDD practices. The addition of event sourcing to the mix might however complicate things, and the once pretty domain is now in shambles. In this post I'll cover the addition of ES, while keeping the awesomeness of DDD in place.

Rolling back migrations to a previous version of Entity Framework Core

I discovered there was a dependency incompatibility between EF Core 5 and SqlKata. I weighted my options, and decided it would be easier to revert back to EF Core 3, than to solve this dependency compatibility issue in another way.

In an attempt to make coordinates legible without resorting to maps I have tried an approach where I describe the position relative to a know point, such as a city, mountain top, or other landmark.
