Today, .NET is cross-platform and open source, enabling applications and services written in C# to run on operating systems including Android, iOS, macOS, and Linux, as well as on Windows.
Every new version of C# has enhanced developer productivity. For example, the most recent versions include new pattern-matching features to make our code more expressive and succinct. Primary constructors and collection expressions help to reduce verbosity in some common scenarios. Various type-system enhancements allow our code to express its requirements and characteristics in more detail, enabling us to write more flexible libraries, and to enjoy better compile-time diagnostics.
