C# 13 Expansion!

Published on 20 Jan 2025.

The C# 13 Expansion is now officially available! You can find this on Gumroad here: https://rbwhitaker.gumroad.com/l/csharp13expansion

This is nine pages long and covers the new C# 13 features, though C# 13 is the smallest update we’ve had in a while.

This also includes four challenges worth 650 XP. I tried to tie into the new C# 13 features when possible, but it’s a small update. So I created a set of challenges that tell a single story that is relevant to the main storyline, and tackled a few spots where I felt like readers could benefit from a few extra challenges, especially around enumerations, tuples, and using multiple objects and classes together.

A Sixth Edition update is also probably in order: I’m making progress on it, and continue to push out weekly early access updates. But we’re still a long way off, and my current best guess is that I’ll likely synchronize it with the release of C# 14 at the end of the year. I’m hopeful that it will be “ready” several months before that, and just waiting for the C# 14 release to go live, but we’ll see how it unfolds.
