C# has evolved significantly over time, from version 1 through the latest version 8. Some key developments include the addition of generics, LINQ, asynchronous programming, and dynamic features. C# continues to focus on productivity and safe, efficient code with recent versions adding capabilities like nullable reference types, async streams, and ranges/indices. .NET has also evolved with improvements to performance and new functionality in versions like .NET Core 2.1. Looking ahead, .NET Core 3 will add support for desktop frameworks like WinForms and WPF.
