C# API Design & Compatibility
Implements extend-only design principles to build stable, backward-compatible C# APIs and distributed systems.
This skill provides specialized guidance for .NET developers on maintaining public API stability using 'extend-only' design principles. It enables Claude to assist in designing NuGet packages, managing binary and wire compatibility for distributed systems, and implementing automated API surface testing. By focusing on immutable functionality and structured deprecation patterns, it ensures that library upgrades remain non-breaking for end-users while allowing for the continuous evolution of features. It is particularly useful for maintainers of high-traffic open-source libraries and enterprise-grade distributed architectures.
