What's Coming to C#?
summary
C# ships point releases 7.1–7.3 with concrete low-level features: ref/in/ref returns/readonly refs for zero-copy structs, and the runtime-and-library-backed Span<T> with slicing and planned ^-indexing and ranges. C# 8 tightens nullability via an opt-in Nullable reference types attribute plus flow analysis that warns on possible null dereference, adds default interface members, async streams (IAsyncEnumerable) and async disposal, and richer pattern matching (switch expressions, recursive and tuple patterns); language design is public on the csharp-lang repo.
