Welcome to Module 2 of the C# & .NET Beginner Course by PrudentCAMPUS NextGen IT Learning.

In this lesson, we go deeper into the core foundation of .NET and then explore every method to create a C# project — perfect for beginners who want clarity and confidence.

🔥 PART 1 — The 4 Pillars of .NET (Explained Simply)

You will understand the main building blocks of the .NET ecosystem:

1️⃣ CLR – Common Language Runtime

The engine that executes C# code

Memory management & garbage collector

Why .NET apps are fast and stable

2️⃣ CTS – Common Type System

Standard rules for data types

How all .NET languages (C#, VB, F#) share types

Why C# is strongly typed

3️⃣ CLS – Common Language Specification

Rules that every .NET language must follow

Ensures cross-language compatibility

Beginner-friendly examples

4️⃣ BCL – Base Class Library

Built-in features (IO, Collections, Networking, Strings, etc.)

Why you rarely need external code for common tasks

Demo with simple examples

By the end of this part, you'll clearly understand how .NET works internally.
