Mediarq.Core

The core of Mediarq — a lightweight, dependency-free CQRS mediator for .NET: commands, queries, no-result commands, notifications, streaming, a composable pipeline of behaviors, built-in validation and Result types. Includes the optional source generator for reflection-free, Native-AOT-friendly dispatch.

dotnet add package Mediarq.Core

Want the core plus the lightweight extensions in one install? Use the Mediarq meta-package.

Quick start

using Mediarq.Extensions;

builder.Services.AddLogging();
builder.Services.AddMediarq(isHttp: false, typeof(CreateOrder).Assembly); // scan for handlers

public record CreateOrder(string Customer) : ICommand<Result<Guid>>;

public class CreateOrderHandler : ICommandHandler<CreateOrder, Result<Guid>>
{
    public Task<Result<Guid>> Handle(CreateOrder request, CancellationToken ct = default)
        => Task.FromResult(Result.Success(Guid.NewGuid()));
}

// inject IMediator / ISender / IPublisher
Result<Guid> result = await sender.Send(new CreateOrder("Alice"));
  • Commands / queries return a Result / Result<T> (railway-oriented); void commands implement ICommand.
  • Notifications (INotification) fan out to zero or more handlers.
  • Streaming (IStreamRequest<T>) returns IAsyncEnumerable<T> via CreateStream.
  • Pipeline behaviors wrap the handler; built-in validation/exception/pre/post light up automatically.

Reflection-free / Native AOT

builder.Services.AddMediarqCore(isHttp: false).AddMediarqHandlers(); // generated at compile time

No assembly scan, no reflection on dispatch. The library is IsAotCompatible and publishes cleanly with Native AOT.

Package Downloads
Mediarq

Lean meta-package bundling Mediarq.Core and the lightweight extensions: ASP.NET Core, FluentValidation, DataAnnotations, Caching, Diagnostics and UnitOfWork. Heavy or opinionated integrations (EntityFrameworkCore, OpenTelemetry, MassTransit, Polly) ship as separate packages — install them explicitly when you need them.
Mediarq.UnitOfWork

Unit of Work pipeline behavior for Mediarq: commit a unit of work around transactional commands.
Mediarq.Diagnostics

Observability for Mediarq: an OpenTelemetry-compatible Activity (tracing) and System.Diagnostics.Metrics behavior per request.
Mediarq.Caching

Caching pipeline behaviors for Mediarq: memoize responses of ICacheableRequest via IMemoryCache (in-memory) or IDistributedCache (e.g. Redis).
Mediarq.FluentValidation

FluentValidation adapter for Mediarq: run FluentValidation validators inside the Mediarq validation pipeline.
