⚠️ Concordia.MediatR has been discontinued

This package is deprecated and will not receive further updates. Starting from version 3.0.0, Concordia has been renamed to Synaptrix, and the MediatR compatibility layer has been removed.

Why was this package discontinued?

Synaptrix v3.0.0 focuses on compile-time source generation via Synaptrix.Generator, which provides zero-allocation, sub-2 ns dispatch. The runtime reflection-based approach offered by Concordia.MediatR is no longer maintained. If you need a MediatR-style AddMediator() call with assembly scanning, consider using MediatR directly alongside Synaptrix.

What should I do?

Remove both Concordia.Core and Concordia.MediatR, then install the Synaptrix meta-package which includes Synaptrix.Core and Synaptrix.Generator:

dotnet remove package Concordia.Core
dotnet remove package Concordia.MediatR
dotnet add package Synaptrix

Migration guide

Before (Concordia + Concordia.MediatR) After (Synaptrix v3.0.0+)
using Concordia; using Synaptrix;
using Concordia.MediatR; (removed — no equivalent)
builder.Services.AddMediator(cfg => ...) builder.Services.AddSynaptrixHandlers()
Runtime reflection-based discovery Compile-time source generation
Concordia.Core + Concordia.MediatR packages Synaptrix meta-package

Update your Program.cs:

// Before
using Concordia;
using Concordia.MediatR;

builder.Services.AddMediator(cfg =>
{
    cfg.RegisterServicesFromAssembly(Assembly.GetExecutingAssembly());
});

// After
using Synaptrix;

builder.Services.AddSynaptrixHandlers();

All interfaces (IRequest, IRequestHandler, INotification, INotificationHandler, IPipelineBehavior, etc.) remain the same — just under the Synaptrix namespace instead of Concordia.

What's new in Synaptrix v3.0.0?

  • ValueTask everywhere: All handler, behavior, publisher, and processor return types changed from Task/Task<T> to ValueTask/ValueTask<T>, reducing allocations on synchronous hot paths.
  • IAsyncEnumerable streaming: New IStreamRequest<TResponse> / IStreamRequestHandler<TRequest, TResponse> interfaces with CreateStream<TResponse>() on ISender for efficient streaming of multiple results.
  • Compile-time only: The source generator produces a sealed GeneratedMediator with constructor-injected handlers and direct type-switch dispatch — no runtime reflection, no DI lookups on the hot path.
