How C# Source Generators Work: The Roslyn Compilation Pipeline Explained
How C# Source Generators Work: The Roslyn Compilation Pipeline Explained Understanding how C# source generators work is one of those things that fundamentally changes the way you think about compile-time code generation. You probably already know what source generators do -- they produce C# source files at compile time, before your application ever runs. But knowing how they plug into the Roslyn compilation pipeline -- and specifically how the IIncrementalGenerator incremental execution model op... Take me to this post.
March 20, 2026CopilotClient and CopilotSession in C#: Core Concepts of the GitHub Copilot SDK
If you want to truly master the GitHub Copilot SDK for .NET, you need to understand CopilotClient and CopilotSession in C#. These two classes form the foundation of everything you'll do with the SDK. CopilotClient manages your connection to the GitHub CLI process, while CopilotSession represents an individual conversation context with the AI.

The Gell-Mann Amnesia Effect of AI is a pretty well documented phenomenon: The Gell-Mann amnesia effect is a cognitive bias describing the tendency of individuals to critically assess media reports in a domain they are knowledgeable about, yet continue to trust reporting in other areas despite recognizing similar potential inaccuracies. Summarizing, AI sounds like a incredible genius synthesizing the world’s knowledge right up until you ask it about the thing you know about, then it’s an idiot... Take me to this post.

March 20, 2026Decorator Pattern Best Practices in C#: Code Organization and Maintainability
Decorator Pattern Best Practices in C#: Code Organization and Maintainability You've learned the decorator pattern. You've built a few wrappers, stacked some logging around a service, maybe wired things up through dependency injection. But knowing the mechanics and knowing how to use them well in a production codebase are different challenges entirely. Decorator pattern best practices in C# go beyond "wrap an interface" -- they cover how to organize your decorators, how to keep them maintainable... Take me to this post.
March 20, 2026Error'd: Yeah Yeah I'm The Tax Man
In only a handful of years, four Liverpudlian scruffs clawed their way from obscurity to unprecedented worldwide celebrity. Yeah, yeah, yeah. Already making a mint from "Money" and other hits, by 1965 they were MBEs, and suddenly discovered class solidarity -- with the rest of the singlet-clad bathers in their grottos of ducats. To be fair, a 97% marginal rate does make it hard for a lad to break into the ranks of true generational wealth. So in 1966, George Harrison and his newly-minted to... Take me to this post.
