Stop Writing if-else! Use Strategy Pattern

In this video, we'll explore the Strategy Design Pattern and learn how it helps you build flexible, maintainable, and extensible applications in C# and .NET 10.

Using a practical shipping cost calculation example, we'll progressively refactor a traditional implementation into a clean Strategy Pattern solution using Dependency Injection and modern object-oriented design principles.
