lousystems.FluentValidation.Extensions

A collection of lightweight, reusable validation extensions for FluentValidation. Designed to simplify complex business rules and maintain clean, readable validators in modern .NET applications.

🚀 Installation

Install the package via .NET CLI:

dotnet add package lousystems.FluentValidation.Extensions

Or via the NuGet Package Manager:

Install-Package lousystems.FluentValidation.Extensions

🛠 Features & Usage

This library extends IRuleBuilder to provide specialized validation logic out of the box.

1. Service Name Validation

Validates strings against common cloud-resource naming conventions (e.g., lowercase, hyphens, specific length).

public class MyRequestValidator : AbstractValidator<MyRequest>
{
    public MyRequestValidator()
    {
        // Mandatory field
        RuleFor(x => x.ServiceName).MustBeServiceName();

        // Optional field: Only validates if not null
        RuleFor(x => x.OptionalService).MustBeServiceNameIfNotNull();
    }
}

2. Conditional Logic

The extensions are built using ApplyConditionTo.AllValidators, ensuring that entire rule chains are correctly skipped when properties are null, preventing unintended validation failures.

🏗 Technical Specifications

  • Target Frameworks: .NET 10.0 (LTS).
  • Dependency: FluentValidation (>= 12.0.0).
  • Native AOT Ready: This library does not use reflection at runtime and is fully compatible with Native AOT (Ahead-of-Time) compilation for high-performance cloud-native workloads.

Technical Implementation Note

When using the IfNotNull variants, the library handles the internal state by wrapping rules in a When condition. This keeps your validator code clean while ensuring strict type safety and null-handling.
