C# is a modern, object-oriented programming language developed by Microsoft and a core component of the .NET ecosystem. It enables building versatile apps for web, desktop, mobile, and games, while being simple, type-safe, and highly productive.

Introduction to C#

• Modern, object-oriented language developed by Microsoft
• Builds versatile apps: web, desktop, mobile, games
• Core component of the .NET ecosystem 🔧
• Simple, type-safe, and highly productive

C# was designed by Anders Hejlsberg in 2000 for Microsoft's .NET platform, with C# 1.0 released in 2002, C# 2.0 adding generics in 2005, and C# 3.0 introducing LINQ in 2007. C# 12 in 2023 brought modern features like primary constructors, collection expressions, and advanced pattern matching.

History of C#

2000: Designed by Anders Hejlsberg Initiated at Microsoft as a modern, object-oriented language for .NET platform. 2002: C# 1.0 Officially Released Launched with .NET Framework 1.0, introducing core syntax and features. 2005: C# 2.0 Introduces Generics Added generics, partial classes, iterators, and anonymous methods. 2007: C# 3.0 Brings LINQ Introduced Language Integrated Query, lambda expressions, and extension methods. 2023: C# 12 and Modern Features Primary constructors, collection expressions, and advanced pattern matching unlocked.

The C# Fundamentals slide outlines syntax basics like classes, methods, and semicolons, plus core data types such as int, string, and bool. It also covers control structures including if/else and loops, OOP principles like inheritance and polymorphism, and practical code examples.

C# Fundamentals

• Syntax Basics: Classes, methods, semicolon terminators
• Core Data Types: int, string, bool
• Control Structures: if/else, for/while loops
• OOP Principles: Inheritance, polymorphism
• Code Examples: Practical demonstrations

The slide "Key Features of C#" displays a grid of six core C# capabilities, each with an icon, heading, and brief description. These include type safety for compile-time error prevention, C/C++ interop for native code integration, garbage collection for automatic memory management, LINQ for SQL-like queries, async/await for responsive apps, and pattern matching for expressive data handling.

Key Features of C#

{ "features": [ { "icon": "🛡️", "heading": "Type Safety", "description": "Compile-time checks prevent type-related runtime errors." }, { "icon": "🔗", "heading": "C/C++ Interop", "description": "Seamless integration with native C and C++ code." }, { "icon": "♻️", "heading": "Garbage Collection", "description": "Automatic memory management eliminates manual allocation." }, { "icon": "🔍", "heading": "LINQ Queries", "description": "SQL-like queries for collections and data sources." }, { "icon": "⚡", "heading": "Async/Await", "description": "Simplifies asynchronous code for responsive applications." }, { "icon": "🎯", "heading": "Pattern Matching", "description": "Expressive matching and deconstruction of structures." } ] }

The slide "C# vs .NET" uses a table to compare their core aspects. C# is a programming language for syntax and code (e.g., "int x=5;"), while .NET is a framework for runtime and libraries (e.g., BCL classes).

C# vs .NET

{ "headers": [ "Aspect", "C#", ".NET" ], "rows": [ [ "Type", "Language", "Framework" ], [ "Role", "Syntax/Code", "Runtime/Libs" ], [ "Example", "int x=5;", "BCL classes" ] ] }

The slide outlines the C# and .NET workflow: developers write C# source code (.cs files), which the .NET Compiler (csc/Roslyn) compiles into IL (MSIL) assemblies. The CLR then loads the assembly and executes it via JIT to native code, leveraging the Base Class Library (BCL).

How C# and .NET Work Together

{ "headers": [ "Step", "Description", "Key .NET Component" ], "rows": [ [ "C# Source Code", "Developer writes C# code (.cs files)", "C# Language" ], [ "Compilation", "csc/Roslyn compiles to IL (MSIL)", ".NET Compiler" ], [ "Assembly Loading", "CLR loads the .exe/.dll assembly", "Common Language Runtime (CLR)" ], [ "Execution", "JIT to native code; uses BCL/APIs", "Base Class Library (BCL)" ] ] }
