Dotnet presents a walkthrough of the latest C# language features from versions 12 to 14, designed to improve coding habits and productivity for developers.

Modern C# Features to Enhance Your Coding Habits

Overview

This session by Dotnet takes you through a range of new and practical features included in C# 12, C# 13, and C# 14—each part of recent LTS (Long-Term Support) releases of the language. These often overlooked features, while small in scope, address real-world developer needs and frequently become favorites due to their impact on day-to-day coding.

Why Focus on Recent C# Features?

• Continuous Productivity: Small language enhancements can significantly improve coding speed and reliability.
• Refresher for All Developers: Whether you regularly work in C# or are returning after some time away, these updates can modernize your development habits.

Key Highlights from C# 12 - C# 14

• Pattern Matching Improvements: More expressive ways to write conditionals and switch statements, leading to cleaner and safer code.
• Primary Constructors for Classes: Simplifies object creation and enhances clarity, especially in immutable types.
• Collection Expressions: Smoother initialization and manipulation of collections, making code more concise.
• Interpolated String Handlers: Advanced string formatting techniques that optimize performance and readability.
• Required Properties: Ensures objects are always properly initialized, helping to catch errors at compile time.
• Extended ‘with’ Expressions: Enables easier and safer object copying and modification, supporting better functional programming patterns.
• Enhanced Type Aliases and Using Declarations: Organize code for greater maintainability and clarity.

Adopting Better Habits

• Review your usage of older constructs and refactor where new features can simplify logic.
