What are the best practices for Fluent Validation?

Fluent Validation is a popular library for .NET that helps in building strongly-typed validation rules. Best practices include keeping your validators clean, using dependency injection for services, and organizing your validation logic.

Can you give me an example of a validation rule?

Sure! For instance, you can create a validation rule for an email field like this: RuleFor(x => x.Email).EmailAddress().WithMessage("Invalid email format.");.

How do I handle complex validation scenarios?

For complex scenarios, consider using custom validators or combining multiple rules. You can also create validation groups to manage different validation contexts.

What should I avoid when using Fluent Validation?

Avoid putting business logic inside your validators. Keep them focused solely on validation to maintain separation of concerns.
