FluentValidation… EXPOSED! | Behind Method Chaining
C# FluentValidation looks like magic — NotEmpty() → WithMessage() → NotNull() just chain together so perfectly.
But how does it actually work?
In this video, I break down the Fluent API design pattern that makes it possible. You’ll discover how interfaces, extension methods, and generics create this clean, readable syntax… and by the end, you’ll be able to build your own Fluent API from scratch.
If you’ve ever used FluentValidation but never understood why it works, this will blow your mind.
