C# 6 introduces features such as indexed members, auto-properties with initializers, static using statements, and support for async/await programming. The Roslyn compiler, celebrated for its open-source status, facilitates easier updates and enhancements to C# in the future. It also enables embedding C# into applications, increasing compatibility and potentially improving build times.
