Every long-lived codebase is haunted. This Halloween, we'll use AI coding agents, along with a few trusty .NET tools, to find and safely banish dead code, …

We thought the series was over, but the demo had one more question for us: can a C# 15 app built on unions, closed hierarchies, and union-aware System.Text.Json …

We store Tiles & Tokens saved games in Postgres with EF Core 11: nested complex types in columns and JSON, indexes on nested complex properties, real execution …

Pause the game, close the app, and resume tomorrow. System.Text.Json in .NET 11 knows about unions - but how much of a C# 15 game state can it save and load out …

Unions are great when the cases are unrelated. When they share behavior, C# 15's closed hierarchies give you a class hierarchy the compiler knows is complete. …

C# 15 adds native union types. We rebuild the Tiles & Tokens turn model as a union, let the compiler catch a missing case, replace a hand-rolled Result<T>, and …

It's your turn. You can roll, play a card, or pass. How does your code know which one happened? We kick off a series on C# 15 and .NET 11 domain modeling by …

Like so many things Aspire, a year makes all the difference, and support for AI coding agents has a whole new approach.

The Aspire dashboard is great. But sometimes you want your telemetry in a terminal.

I wrote about the Aspire CLI ten months ago. Here's what changed, and what I got wrong.
