C# 10 Features: What's New in the Language

Introduction

C# 10 introduces several new features and enhancements that further improve the language's capabilities and developer experience. This guide provides an overview of the key features introduced in C# 10 and includes sample code to demonstrate how to use them effectively.

Key Features in C# 10

C# 10 brings several exciting features to the language, including:

• Global Usings: Global usings simplify the process of importing namespaces and make code cleaner and more concise.
• File-Scoped Namespaces: You can now define namespaces at the file level, reducing clutter and improving code organization.
• Interpolated Strings as Format Strings: C# 10 allows you to use interpolated strings as format strings, improving string formatting and readability.
• Improved Target-Typed Conditional Expression: Target-typed conditional expressions simplify type inference and reduce code verbosity.
• Extended Property Patterns: Property patterns now support additional conditions, enhancing pattern matching capabilities.

Sample Code

Below are sample C# code snippets that demonstrate the use of some of the new features introduced in C# 10.

C# Code (Global Usings Example):

// Before C# 10
using System;
class Program
{
    static void Main()
    {
        Console.WriteLine("Hello, C# 10!");
    }
}
// C# 10
Console.WriteLine("Hello, C# 10!");
    

C# Code (File-Scoped Namespace Example):

namespace MyNamespace;
class Program
{
    static void Main()
    {
        Console.WriteLine("C# 10 features");
    }
}
    

Conclusion

C# 10 introduces exciting new features that enhance the language's capabilities and make it more developer-friendly. Features like global usings, file-scoped namespaces, and improved type inference simplify code and improve readability. By incorporating these features into your C# applications, you can enjoy a more streamlined and efficient development experience.
