C# Kaigi 2026
Overview
The first community conference dedicated to C#. Japan had joint .NET study groups but no standalone C# event at scale, and this fills that gap from its 2026 launch. neuecc delivers the keynote on the state of C# today. Deliberately small and in-person only, it runs 12 CfP-selected sessions plus 10 lightning talks.
Speakers
- neuecc (2026 keynote, "The State of C# — Its Evolution and .NET Everywhere in the AI Era")
- nenoNaninu (C# Kaigi organizer; 2026 proposal review)

Japan's C# community had long been scattered across corporate study groups and joint events such as BuriKaigi, with no conference devoted to the language alone. The 2026 debut is an attempt to establish a venue of its own for C# developers.
