Create Types on Demand and Cecilifier
This post is part of C# Advent Calendar 2025. Visit it for all the awesome upcoming posts!
The traditional C# Advent is here. Usually I give some daily and practical advice. Like testing tips [1] or some outsider view approach to C# [2] here. This time its more about fun with very niche applications.
Provide 'Just In Time' Types & Code?
In dotNet there are facilities to create types at Runtime. This exists of two things:
A callback that is called when a type isn’t found.
Loading and generating Assemblies at runtime.
Learned/Discovered this week: bpftrace, Windows in Docker, Testcontainers & Docker upgrade, Debugging-Tips

(Even Windows has it). bpftrace compiles things to eBPF programs to do the tracing, so it works on must Linux flavors.
Found via Brendan Gregg. Its one of the best resources for performance debugging.

I am using Bitbucket pipelines in this post. And I’m a newcomer at that =).
