FeedR moves every tick between services through a two-method streaming abstraction with a no-op default and a Redis implementation - which, despite the namespace, is pub/sub rather than streams. What that seam buys, how DI last-wins overrides it, and what you lose when nobody is listening. Part 4 of the FeedR deep dive.
FastEndpoints binds a single request DTO from JSON, form, route, query, claims, headers, cookies and permissions - in that order, with compiled setters cached per DTO type. Reading the binder explains every binding surprise I have ever hit. Part 4 of FastEndpoints in Depth.
An annotated tour of the JSON document Pactify produces - the serializer settings that shape it, the snake_case field inherited from Pact v1, and the unusual decision to ship the consumer's matching options inside the contract itself.
Every stored payload carries a __version stamp; every read walks it up one step at a time. This part dissects VersionKit's lazy migration pipeline - the MigrationRunner API, the JsonElement traps System.Text.Json sets for dictionary code, and reading history on purpose. Part 4 of the Entity Versioning with VersionKit series.
Rename, move, add, remove, type change - VersionKit's attribute surface covers five kinds of schema evolution. This part walks the whole declarative API, the merge rules behind stacked attributes, and what the attributes deliberately refuse to express. Part 2 of the Entity Versioning with VersionKit series.
Rename a property, change a type, ship the release - and every payload you stored last year stops deserialising. Introducing VersionKit, a .NET library that declares schema history as attributes and migrates old data on read.
