TimeWarp.Mediator.Contracts

Message contracts for TimeWarp Mediator 14.0: one set of requests, commands, queries, notifications, and pipeline types for both dispatchers.

Install

dotnet add package TimeWarp.Mediator.Contracts --version 14.0.0

A generated host also needs TimeWarp.Mediator.Generators at the same version. A reflection host needs TimeWarp.Mediator instead. Keep every TimeWarp.Mediator package on 14.0.0.

Example

public sealed class Ping : IRequest<string> { }

public sealed class PingHandler : IRequestHandler<Ping, string>
{
  public Task<string> Handle(Ping request, CancellationToken cancellationToken) =>
    Task.FromResult("Pong");
}

services.AddGeneratedMediator();
string reply = await provider.GetRequiredService<ISender>().Send(new Ping());

AddGeneratedMediator() is emitted into the host project. Call it from the host, not from this contracts assembly. Reference only this package from a project that declares messages and does not dispatch them.

Migration

14.0.0 is not a drop-in for 13.0.0.

  • This package and TimeWarp.Mediator target net10.0 only. Stay on 13.0.0 if you cannot.
  • AddMediator() does not register the generated mediator. A generated host calls AddGeneratedMediator().
  • The generated dispatcher does not run streams, pre/post processors, or the exception cascade.
  • From MediatR: change using MediatR; to using TimeWarp.Mediator; and AddMediatR to AddMediator.

Matrix and steps: 13.x reflection to 14.x generated.

Package Downloads
TimeWarp.State

State management for .NET. Blazor components, JavaScript interop, and render subscriptions are in TimeWarp.State.Blazor.
TimeWarp.Nuru

Route-based CLI framework for .NET - batteries included with telemetry, REPL, and shell completion
TimeWarp.Mediator

Reflection-based mediator (MediatR fork): AddMediator() registers request/response, notifications, streams, and pipeline behaviors over Microsoft.Extensions.DependencyInjection by assembly scan. The source-generated, AOT-friendly dispatcher is separate (TimeWarp.Mediator.Contracts and TimeWarp.Mediator.Generators, AddGeneratedMediator) and does not reference this package.
TimeWarp.State.Telemetry

OpenTelemetry instrumentation for the TimeWarp.State mediator pipeline: action spans, timing, and opt-in AOT-safe state snapshots.
