Common Language Runtime (CLR) in .NET | How C# Code Runs on CPU

In this video, we’ll explore the Common Language Runtime (CLR) — the heart of the .NET platform that executes your C# applications. You’ll learn how C# code is transformed step by step into machine code and executed by the CPU, plus the key runtime services CLR provides like garbage collection, type safety, and exception handling. 👉 What you’ll learn in this video: What is the CLR (Common Language Runtime)? The full execution flow (C# → IL → JIT → Native Code → CPU) How the C# compiler generates Intermediate Language (IL) Role of the JIT (Just-in-Time) compiler CLR services: garbage collection, memory management, type safety, exception handling Why CLR makes .NET powerful, safe, and cross-language compatible 📌 Execution Flow: 1️⃣ C# Code (High-Level Language) ⬇️ compiled by C# Compiler 2️⃣ IL Code (Intermediate Language / MSIL / CIL) ⬇️ compiled by JIT Compiler at runtime 3️⃣ Native Code (Machine Code) ⬇️ executed by CPU 🔗 Connect with me on social media: 📘 Facebook: https://www.facebook.com/profile.php?id=61556070852046 📸 Instagram: https://www.instagram.com/deathstrokes505/ 🐦 Twitter/X: https://x.com/deathstrokes505 🌐 Website/Blog: https://logicsunboxed.blogspot.com/ Timestamp: 0:00 – Intro: The magic of code 0:37 – The puzzle: Humans vs CPU language 1:24 – Step 1: Compilation → C# to IL 2:24 – Step 2: CLR – The control tower 3:26 – Step 3: JIT Compiler – Just in Time translation 3:54 – Full journey recap: From C# to machine code 4:16 – Why this process?
