I've been using @cakebuild.net for a long time, it is really great!To be able to write C# to make up all your build tasks and everything around it, test it locally and just minimally bootstrap Cake in your yml file for your CI workflow.

Thanks to @devlead.se and the Cake team for their dedication!

Thanks for the kind words❤️Made my Friday.

Cake wouldn't be were it is without people like you in it's community!

Cake's dedication is a marathon, activity levels might vary, but aim for long-term longevity, we've been in/out of fashion multiple times over the past 12 years, but our focus the same.

It sometimes... feels slightly inefficient and risks to make same mistakes again and again.

One interesting thing about corporate reorgs is that, as a contributor, consumer, or consultant, you can find yourself in meetings where you know more about the history of their products than they do.🤷

Captain Haddock looking very frazzled, saying, “What a week, huh?”
Tintin leans into the frame and says, “Captain, it’s Wednesday.”
Snowy aka Milou is very excited about the drink he has found.

Viñeta de Tintin
El capitán Haddock, sentado a una mesa y con aspecto de estar agotado, dice: "¡Menuda semana, ¿eh?".
Tintín, a su derecha, le dice: "Capitán, es miércoles".
A la izquierda, Milú mira muy contento la bebida que está en la mesa.
