Web API Project Address Book with source code in GitHub | REST APIs | C# | Web API Best Practices
In this video we first build a simple fully functioning Web API project Address Book. After that, we are slowly making it better by adding Services, DTOs (Data Transfer Objects), Interfaces, Dependency Injections, Data Validation and Asynchronous Programming.
