Where is C# headed?

" summary

C# 8 preview adds nullable reference types that are compile-time only (enabling it often produces thousands of warnings) and a flow-analysis model that reduces but does not eliminate null refs; async streams via IAsyncEnumerable plus await foreach for producing/consuming async iterators; switch expressions, target-typed new, Index/Range types (slicing arrays returns copies unless using Span), and default interface methods which require a new runtime CLR. Demos compile intermittently in preview and some tooling/parsing bugs remain.
