C# 14 Samples

This project contains comprehensive samples demonstrating the new features introduced in C# 14. Each sample focuses on a specific language enhancement and includes detailed explanations, code examples, and practical use cases.

Sample Projects

Project	Feature	Description
CompoundAssignment	User-Defined Compound Assignment Operators	Demonstrates how to implement compound operators (+=, -=, etc.) as instance methods with void return type for in-place mutation and zero allocations. Perfect for performance-sensitive structs and large classes.
ExtensionMembers	Extension Members	Comprehensive guide to the new extension member syntax that enables extension properties, static extension members, and better organization of related functionality. Includes examples of traditional vs. new syntax, generic extensions, and IL inspection tools.
Fields	The field Keyword	Explores the contextual field keyword that provides direct access to compiler-synthesized backing fields. Covers property validation, caching, data transformation, and change notification patterns.
LambdaModifiers	Lambda Parameter Modifiers	Shows how to use parameter modifiers (ref, in, out, scoped, ref readonly) on lambda parameters without requiring explicit type declarations, enabling more concise and readable lambda expressions.
NameofGenerics	nameof with Unbound Generic Types	Demonstrates using the nameof operator with unbound generic types (e.g., nameof(IList<>)), providing a type-safe way to reference generic type names without specifying type arguments.
NullConditional	Null-Conditional Assignment	Demonstrates the ability to use null-conditional operators (?., ?[]) on the left-hand side of assignments and compound assignments, reducing the need for explicit null checks.
SpanConversions	First-Class Span Conversions	Covers the new implicit conversions for Span<T> and ReadOnlySpan<T> types, including array-to-span, span-to-readonly-span, covariant spans, and string-to-readonly-span conversions for allocation-free operations.
