C# Singleton Pattern: Basics of Creational Design Patterns

Managing shared resources like configuration settings or database connections can lead to unexpected bugs if multiple instances conflict. The Singleton pattern solves this by guaranteeing that a class has only one instance while providing a global point of access. This text-based course guides you through the foundational concepts of creational design patterns, focusing on how to implement, optimize, and safely use the Singleton pattern in modern C# applications. What you'll learn: - Understand the core concepts of creational design patterns and why the Singleton pattern is used. - Implement basic Singleton classes in C# using standard and modern syntax. - Apply thread-safety techniques, including double-check locking and the Lazy type, to prevent concurrency issues. - Explore how Singleton lifetimes integrate with modern Dependency Injection containers. - Avoid common pitfalls and anti-patterns associated with global state in software design. - Practice your skills through written coding exercises and step-by-step structural walkthroughs. You will start with essential definitions and structural concepts represented in text, then move on to step-by-step implementation strategies, thread-safety patterns, and modern dependency injection practices. This course is designed for beginner C# developers who want to write cleaner, more organized code, with no prior knowledge of design patterns required.
