Valit

Valit uses a clean, chainable syntax for defining validation rules, making code more readable and maintainable, as demonstrated in the registration model example with methods like Ensure() and Required().

The library emphasizes a 'dead simple' approach, reducing scattered if-statements and boilerplate code for common validation scenarios like email format and length checks.

Supports custom error messages, error codes, tags, and conditions, allowing developers to tailor validation behavior without modifying core logic, as mentioned in the README's extensibility features.

Seamlessly validates objects such as registration models with practical criteria, and integrates via NuGet with minimal setup, as shown in the getting started example.
