C# 14 introduces extension members
Briefly

C# 14 introduces significant enhancements with extension members, enabling developers to augment existing types through new methods and properties without the need for type modification. This update aligns with Microsoft’s belief in improving code usability and flexibility. The latest preview incorporates both static extension methods and instance properties, allowing developers to create customized methods like IsEmpty() for better code practices. The new optional syntax facilitates ease of use while maintaining backward compatibility, ensuring developers can seamlessly adopt these enhancements without disruption to their existing codebase.
Extension members in C# 14 will let developers add methods and properties to existing types without modifying the type or recompiling, enhancing flexibility.
The implementation of static methods and properties as extension members provides new options for developers, improving code usability without adding complexity to existing codebases.
Microsoft's Kathleen Pollard highlights that the alternative syntax for extension methods simplifies development, allowing users to enhance types while retaining existing functionality.
Developers now have the ability to create their own extension methods like IsEmpty(), promoting more intuitive coding practices and easier management of type behaviors.
