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.

Representing coordinates in a human readable way

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.
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

Similar string search with the Levenshtein distance on SQL Server
Recently I have been looking for more flexible ways to search through text within a SQL database, and I stumbled upon a suggestion which indicated to use the so called Levenshtein distance.
