This is the official repository for the design and evolution of the C# programming language. It's where language features are proposed, discussed, designed, and specified. It contains feature proposals, notes from language design meetings, and the evolving specification. Language Design Meetings (LDMs) are held by the LDT and occasional invited guests, and are documented in Design Meeting Notes in the meetings folder, organized in folders by year. The lifetime of a design meeting note is described in meetings/README.md. LDMs are where decisions about future C# versions are made, including which proposals to work on, how to evolve the proposals, and whether and when to adopt them. Parsing (if applicable) should be resilient to experimentation: typing should not cause crashes.

Features

  • Hosts active and historical C# feature proposals
  • Maintains notes and minutes from Language Design Meetings (LDMs)
  • Includes detailed speclets (proposed language text) and design processes
  • Tracks proposal statuses and milestones for language enhancements
  • Encourages community engagement via issues and discussions
  • Coordinates closely with Roslyn (C# compiler) implementation
