The C# SDK tracks implementation of MCP spec components using the modelcontextprotocol project boards, with a dedicated project board for each spec revision. For example, see the 2025-11-25 spec revision board.

The next MCP specification revision is being developed in the protocol repository. The C# SDK already has experimental support for Tasks (experimental in the specification), which will be updated as the specification is revised.

The C# SDK team is actively responding to feedback and continuing to explore end-to-end scenarios for opportunities to add more APIs that implement common patterns.

See the milestones page to see which issues and features are being planned for future versions.

For more information about the C# SDK's approach to versioning, breaking changes, and support, see the Versioning documentation.
