Template Method Design Pattern in C#

The Template Method design pattern is a behavioral pattern that allows the reuse of an algorithm's structure while enabling subclasses to redefine certain parts of the algorithm. The pattern entails defining a top-level public routine in an abstract base class that is inherited by concrete classes. Key components include private/protected methods, abstract methods, and virtual methods, each serving a specific role in the algorithm's execution. This approach ensures maximum code reuse and allows for easier adaptation of variations. An example in C# includes refactoring reporting services to adhere to this pattern, enhancing code maintenance and reducing redundancy. However, potential trade-offs include reduced adaptability and increased error-proneness due to the control residing in the base class.
