The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance, making it ideal for centralized functionalities.
This article discusses implementing a thread-safe Singleton in C#, highlighting both the classic double-checked locking pattern and the modern Lazy<T> approach for better performance.
Typical use cases for Singleton include logging, configuration management, and database connections, where a shared instance provides efficiency and consistency throughout the application.
By utilizing a private constructor and a static field, the Singleton pattern effectively restricts instantiation while providing global access through the Instance property.
