    C# is cool again and you can't avoid it anymore...

    C# has evolved significantly from its enterprise-focused origins into a modern, cross-platform language with features like records, pattern matching, nullable reference types, and async/await. The .NET ecosystem has been transformed with .NET Core (now simply .NET), offering cross-platform support, modular architecture, and excellent performance. Modern C# includes minimal APIs for quick web development, LINQ for database querying, source generators for compile-time code generation, and frameworks like Blazor for frontend development and MAUI for cross-platform mobile apps.

    Passkey support for ASP.NET Core identity
