What’s Next in C#
summary
Repository links and meeting notes show active design work and a preview compiler; expect experiments in the repo and docs. Concrete proposals: removing the using-alias limitation, adding primary constructors for all classes with captured parameters, introducing collection literals using [] plus a spread operator that maps to many collection types, and a special field variable for auto-properties (raising deliberate warnings/upgrade tooling for the potential breaking change). Most demos compile in preview; some features remain under discussion.
