Key Features of C# 13 for Developers
- Params Collections
Expands params support to collection types, allowing C# developers to pass a variable number of arguments more efficiently.
- New Lock Type and Semantics
Introduces an advanced lock type, improving synchronization mechanisms in multithreaded applications.
- New Escape Sequence
\e: Adds the \e escape sequence for the ESCAPE/ESC character (U+001B), enhancing string handling capabilities.
- Method Group Natural Type Improvements
Optimizes the compiler’s ability to infer types for method groups, making code more concise and readable.
- Implicit Indexer Access in Object Initializers
Allows indexers to use implicit Index/Range access in object initializers, simplifying collection initialization.
- Ref Locals and Unsafe Contexts in Iterators and Async Methods
Enables the use of ref locals and unsafe contexts within iterators and asynchronous methods, providing greater flexibility for performance-critical scenarios.
- Ref Struct Types Implementing Interfaces
Allows ref struct types to implement interfaces and introduces the allows ref struct constraint, increasing expressiveness in low-level programming.
- Partial Properties and Indexers
Supports the use of the partial modifier to split a property or indexer across multiple parts, enhancing code organization.
- Overload Resolution Priority
Enables API authors to control method overload selection priority using System.Runtime.CompilerServices.OverloadResolutionPriority, offering finer control over API design.
