Introducing C# 10: New Features in .NET 6


What’s New in C# 10?

C# 10, the latest version of the popular programming language, comes loaded with new features that promise to make developers’ lives easier. With the release of .NET 6, there’s a lot to look forward to in terms of improved functionality and enhanced performance.

Record Types

One of the most exciting additions to C# 10 is the introduction of record types. This new feature allows developers to create immutable data types with minimal code. By using the new “record” keyword, developers can define a type with a set of readonly properties, making it easier to work with complex data structures.

File-Scoped Namespaces

In C# 10, file-scoped namespaces provide a new, more intuitive way to organize and structure code. This feature allows developers to define namespaces directly within a file, eliminating the need for separate namespace blocks at the top of each file. This simplifies the code and makes it easier to understand and maintain.

Global Using Directives

Global using directives in C# 10 allow developers to import namespaces across an entire project, reducing the need for repetitive “using” statements in each file. This makes it easier to manage dependencies and reduces the amount of boilerplate code required.

Interpolated String Handlers

Interpolated string handlers in C# 10 provide a new way to customize the behavior of string interpolation. Developers can now create their own custom handlers to process interpolated strings, adding a new level of flexibility and extensibility to string formatting in C#.


With C# 10 and .NET 6, developers can look forward to a host of new features and improvements that will streamline the development process and make it easier to write clean, efficient code. From record types to file-scoped namespaces and global using directives, C# 10 is shaping up to be a game-changer for developers working with .NET.
