Simplify Validation in .NET Core with Fluent Validation

When building applications, input validation is a critical piece for ensuring data integrity and providing a smooth user experience. With Fluent Validation, you can define clean, readable, and reusable validation rules in your .NET Core applications.

Here’s why I recommend Fluent Validation:
✅ Readable Syntax: Build validation rules using a fluent API that’s easy to understand and maintain.
✅ Centralized Logic: Keep validation separate from controllers or business logic, ensuring better separation of concerns.
✅ Reusability: Write validators once and reuse them across your application.
✅ Customization & Localization: Add custom error messages and support multiple languages.
✅ Integration Ready: Works seamlessly with ASP.NET Core’s validation pipeline and supports dependency injection.
✅ Async Validation: Perfect for scenarios like database checks or external API calls.

Fluent Validation makes it easier to write robust validation logic while keeping your code base clean and maintainable.
