This course will teach you how to use FluentValidation library to perform validation in ASP.NET Core applications. FluentValidation is a free and open-source library developed by Jeremy Skinner at https://fluentvalidation.net
Input validation is a vast and complicated topic, and it’s often unclear what tools to use and best practices to follow in this area. In this course, FluentValidation Fundamentals, you’ll learn to perform validation in ASP.NET Core applications. First, you’ll explore the features of the FluentValidation library. Next, you’ll discover how to combine them with DDD best practices. Finally, you’ll learn how to use attributes as an alternative to the library. When you’re finished with this course, you’ll have the skills and knowledge of validation and the FluentValidation library needed to perform validation in any ASP.NET Core application. FluentValidation is developed by Jeremy Skinner.
Course Overview Hi everyone, my name is Vladimir Khorikov, and welcome to my course FluentValidation Fundamentals. I'm very excited to share this course with you. Validation is a surprisingly complex topic. Even though we all work with validation on a daily basis, it's often hard to choose between multiple, seemingly equally valid approaches to validation. This course will help you build the right mental model and understand how you should deal with validation, and why exactly you should prefer one approach over another. You will learn about the foundational principles of validation, how they relate to domain‑driven design, and how to use the FluentValidation library to apply those principles in practice. Some of the major topics that we will cover include the FluentValidation library, always‑valid domain model, the Value Object design pattern, and explicit application errors. By the end of this course, you will know everything needed to start applying proper validation techniques with the help of the FluentValidation library in your own projects. Before beginning this course, you should be familiar with the C# programming language and ASP.NET. I hope you will join me on the journey to learn about validation here at Pluralsight.
