Decorator Pattern + DI = EASY

Summary

The transcript discusses the decorator pattern in .NET Core as a method for adding functionality, specifically caching, to an existing class without modifying its original implementation. The key technique involves creating a new repository that extends the base member repository and introduces caching capabilities as an additional layer of functionality. By using the decorator pattern, developers can enhance class behavior dynamically and adhere to the open-closed principle of software design. This approach provides a flexible way to add features like caching to repositories without directly altering the underlying code structure.
