MessageValidation.ImmediateValidations

An Immediate.Validations adapter for MessageValidation — bridge source-generated, AOT-friendly, zero-reflection validators into the MessageValidation pipeline.

Installation

dotnet add package MessageValidation.ImmediateValidations

Quick Start

1. Decorate your message

Mark the message type with [Validate], make it partial, and implement IValidationTarget<T>. The Immediate.Validations source generator emits the Validate method at compile time.

using Immediate.Validations.Shared;

[Validate]
public partial record TemperatureReading : IValidationTarget<TemperatureReading>
{
    [NotEmpty]
    public required string SensorId { get; init; }

    [GreaterThanOrEqualTo(-50)]
    [LessThanOrEqualTo(150)]
    public required double Value { get; init; }
}

2. Register the adapter

builder.Services.AddMessageValidation(options =>
{
    options.MapSource<TemperatureReading>("sensors/+/temperature");
});

builder.Services.AddMessageImmediateValidations();

That's it. The pipeline will call the source-generated TemperatureReading.Validate(...) static method for every incoming message — no reflection, no DI lookup per validation, AOT- and trim-friendly.

Why use this adapter?

Concern DataAnnotations / FluentValidation Immediate.Validations
Reflection at runtime ✅ Yes ❌ None
AOT / trim compatibility ⚠️ Partial ✅ Full
Errors caught at compile time ❌ No ✅ Yes (analyzers + source gen)
Automatic NRT null checks ❌ No ✅ Yes
