Harvey Myers IV is a software developer with more than four decades of experience building business software, solving production problems, and adapting to wave after wave of platform change. His work has ranged from early systems with tight memory and hardware constraints to modern .NET applications built for clarity, maintainability, and long-term usefulness.   In this book, he brings that long-view perspective to Blazor development, using a 3D Tic-Tac-Toe project to teach architecture, state management, persistence, and interactive UI design in a practical way. The project may be a game, but the lessons are meant for real software.
