Kotlin vs C#: The Epic Battle
summary
Live code comparison shows concrete tradeoffs: Kotlin uses coroutines vs async/await semantics and compiler plugins to generate blocking wrappers and HTML DSLs, while C# uses source generators to emit INotifyPropertyChanged and exposes Span/value types, unsafe blocks and ref structs for low-allocation code. Benchmarks claim Ktor hits ~356k req/s and .NET native AOT now compiles to WebAssembly with EF Core support. Kotlin wins on Android and multiplatform reuse (Kotlin multiplatform), C# wins on games, desktop and fine-grained memory control (native AOT to WebAssembly).
