EasyValidate

A modern, type-safe .NET validation library and source generator with Roslyn analyzers and code fixers.

Overview

EasyValidate enables powerful, composable, and type-safe validation using attributes. It generates efficient validation code at compile time and provides analyzers for compile-time feedback.

Quick Start

public class User
{
    [Required]
    [StringLength(50)]
    public string Name { get; set; }
    
    [Required]
    [Email]
    public string Email { get; set; }
    
    [Range(18, 120)]
    public int Age { get; set; }
}

// Generated validation method
var result = user.Validate();
if (!result.IsValid)
{
    foreach (var error in result.Errors)
    {
        Console.WriteLine(error.Message);
    }
}
