OSS Power-Ups: FluentValidation – Webinar Recording

The recording of our webinar, OSS Power-Ups: FluentValidation, with Jeremy Skinner, is now available. Subscribe to our community newsletter to receive notifications about future webinars.

This is the start of our series of OSS Power-Ups, where we want to put a spotlight on open-source .NET projects. FluentValidation is a library for building strongly-typed validation rules, with amazing popularity, and over 50 million downloads on NuGet. Jeremy Skinner, the maintainer, will help us get started with some basic examples, writing custom validators, localizing error messages, and integrating the validation into ASP.NET Core.

We also have a couple of surprises for Jeremy and the users of FluentValidation to reveal. Don’t miss it, you’ll love it!
