ZeroAlloc.Validation
Source-generated, attribute-based validation for .NET that allocates nothing on the valid path. The source generator emits a strongly-typed validator class at build time — no reflection at runtime. When all rules pass, the entire validation cycle produces zero heap allocations.
Install
dotnet add package ZeroAlloc.Validation
30-Second Example
using ZeroAlloc.Validation;
[Validate]
public class CreateOrderRequest
{
[NotEmpty][MaxLength(50)] public string Reference { get; set; } = "";
[GreaterThan(0)] public decimal Amount { get; set; }
[NotEmpty][EmailAddress] public string Email { get; set; } = "";
}
// The source generator emits CreateOrderRequestValidator at build time
var request = new CreateOrderRequest
{
Reference = "ORD-2026-001",
Amount = 99.99m,
Email = "customer@example.com"
};
var validator = new CreateOrderRequestValidator();
var result = validator.Validate(request);
if (!result.IsValid)
foreach (ref readonly var f in result.Failures)
Console.WriteLine($"{f.PropertyName}: {f.ErrorMessage}");
