Learn C# with CSharpFritz - Ep9: SOLID Principles and Dependency Injection

From the creator

We've covered the basics of the C# language, but have not yet gotten any practical advice on object design and interaction. In this episode, Fritz talks about the SOLID design principles and applying them to C# classes and interfaces. We conclude with a quick discussion of Dependency Injection and the ASP.NET Core dependency injection container.
