Pacco's Operations service listens to all eighty messages in the estate while owning zero contract classes - it reads a JSON registry and forges the CLR types at runtime with Reflection.Emit. The estate's answer to the shared-contracts problem, and the drift it cannot see.
How ArchiveKit wires itself up - the [Archivable] attribute's three knobs, an assembly scanner that fails fast at startup instead of quietly at delete time, the static registry behind every lookup, and the AddArchiveKit configuration surface. Plus an honest note about the source generator that doesn't exist yet. Part 5 of the Archive-on-Delete with ArchiveKit series.
DShop.Common stamps a server-generated Guid into an immutable command by reflecting into its compiler-generated backing field - immutability the type system only pretends to enforce.
Operations subscribes to every command and event in the estate by reflection and routes them through two open-generic handlers - a neat trick with one dead limb the wiring can never light. Part 8 of Nine Services and a Message Bus.
AddFastEndpoints never asks you to register an endpoint. Reading the discovery code shows how a reflection scan over five interfaces becomes a validated endpoint catalogue - and which mistakes it turns into startup crashes on purpose. Part 2 of FastEndpoints in Depth.
At startup VersionKit reflects over your model assembly and compiles property attributes into an executable pipeline - one migration step per version pair, five operation types, all of them deliberately idempotent. Part 3 of the Entity Versioning with VersionKit series.
HTML templates seeded in OnModelCreating, a reflection mini-language that resolves hash-brace tokens against a model, a Gmail-versus-SMTP environment branch, Cc quietly added into To, and string.Format run over raw HTML.
