What are the new features in the latest C# version

C# has evolved significantly with the release of its latest version, bringing a host of new features aimed at enhancing productivity, performance, and ease of use for developers.

New Features in C# 11

  • Raw String Literals: This feature allows for multi-line strings without the need for escape sequences, making it easier to work with strings that contain quotes or special characters.
  • Required Members: This introduces the ability to define properties or fields that must be initialized when creating an instance of a class or record.
  • Generic Math Support: Expands support for mathematical operations on generic types, enabling more flexible and reusable code.
  • File-scoped Types: This feature allows developers to define a class, struct, or interface at the file scope rather than within a namespace, simplifying the structure of code files.
  • Improvements to Pattern Matching: Enhancements to pattern matching syntax lead to more expressive and concise code.

Example of Raw String Literals

var multiLineString = """ This is a multi-line string that supports "quotes" too. """;
