TL;DR
A developer reports that pressing Tab does not accept the expected autocomplete suggestion and instead offers an unrelated completion. The post calls on Microsoft — or specifically the C# Dev Kit plugin team — to address the behavior.
What happened
In a short blog post and accompanying screenshot, a developer described a frustrating autocomplete experience: when they press the Tab key to accept a suggestion, nothing happens and the editor proposes a different completion that wasn't among the two initial options. The author singled out Visual Studio Code's autocomplete behavior and specifically mentioned the C# Dev Kit plugin as a likely locus of the issue. The entry is a public appeal to whoever oversees this behavior at Microsoft (or within that plugin) to fix the interaction. The post is dated November 26, 2025, and includes a terse, humorous author bio identifying Ivan Castellanos as the writer.
Why it matters

- If widespread, the issue could affect developers' editing workflows when using the referenced tooling.
