What problem does it solve?

This Skill helps you implement robust data validation in your .NET applications using built-in features, ensuring data integrity and preventing invalid states without relying on external libraries for common scenarios.

Core Features & Use Cases

• Declarative Validation: Leverage DataAnnotations for property-level checks like [Required], [Range], and [StringLength].
• Cross-Property Validation: Implement IValidatableObject for complex rules spanning multiple properties within a single object.
• Options Validation: Securely validate application configuration using IValidateOptions<T> at startup.
• Custom Attributes: Create reusable, domain-specific validation logic.
• Use Case: Validate a user registration form, ensuring all required fields are present, email formats are correct, and password complexity rules are met before processing.

Quick Start

Use the dotnet-validation-patterns skill to generate C# code demonstrating how to validate a CreateProductRequest model using DataAnnotations.
