Show HN: PipelinePlus – plug-and-play MediatR pipeline behaviors for .NET

PipelinePlus bundles common MediatR pipeline behaviors into a small, plug-and-play library to reduce boilerplate in .NET apps.

What’s included:
– Validation (FluentValidation)
– Caching (attribute-driven with opt-out)
– Idempotency (deduplicate command handling)
– Outbox (persist and dispatch events)
– Performance (timing hooks)
– Exception mapping (turn exceptions into consistent results/logs)

Motivation: In most MediatR projects, these cross-cutting concerns get reimplemented again and again. PipelinePlus aims to make them composable, testable, and easy to adopt without locking you in.

Install:
dotnet add package PipelinePlus

Minimal usage:
// Program.cs / composition root
services.AddMediatR(typeof(Program));
services.AddPipelinePlus(); // registers the behaviors

  // Example request
  [Idempotent]
  public record CreateOrder(Guid Id, string Sku) : IRequest;

  // Example validator (FluentValidation)
  public class CreateOrderValidator : AbstractValidator {
    public CreateOrderValidator() {
      RuleFor(x => x.Sku).NotEmpty();
    }
  }

Notes:
– Outbox/Idempotency plug into your own storage abstractions.
– Works on .NET 8/9 and latest MediatR.
– MIT licensed.

Feedback welcome—API shape, naming, and ideas for the next behaviors (e.g., OpenTelemetry integration, Redis/distributed cache helpers).
