C# Introduction & The .NET 8 Ecosystem
CLR runtime, cross-platform .NET, top-level statements, and C# basics
Created by Microsoft and Anders Hejlsberg, C# is an elegant, type-safe, object-oriented language that runs on the high-performance cross-platform .NET runtime across Windows, Linux, and macOS.
The Modern C# Architecture
Common Language Runtime (CLR): The virtual machine managing execution, memory garbage collection, and JIT (Just-In-Time) compilation to machine code.
Top-Level Statements: In modern C# (.NET 6+), boilerplate class and main method declarations can be omitted for simple scripts.
String Interpolation: Embed expressions inside strings using $"Hello {name}".
// Modern C# 12 Top-Level Statements
string studentName = "Sameera";
int score = 98;
