Introducing Trax

We're excited to announce the public launch of Trax — a .NET framework for building business logic as composable, type-safe pipelines.

What is Trax?

Trax brings Railway Oriented Programming to .NET. Instead of scattering error handling across your codebase, you build trains — typed pipelines of junctions where each junction's output feeds the next. If any junction fails, the rest are skipped automatically.

public class ProcessOrderTrain : Train<OrderRequest, OrderReceipt>
{
    protected override async Task<Either<Exception, OrderReceipt>> RunInternal(OrderRequest input)
        => Activate(input)
            .Chain<CheckInventoryJunction>()
            .Chain<ChargePaymentJunction>()
            .Chain<CreateShipmentJunction>()
            .Resolve();
}

Layered Architecture

Trax is designed so you can use only what you need:

• Trax.Core — just pipelines, no infrastructure
• Trax.Effect — add execution logging and DI
• Trax.Mediator — decoupled dispatch
• Trax.Scheduler — cron schedules, retries, dead letters
• Trax.Dashboard — Blazor monitoring UI

Get Started

Install the template and scaffold a project:

dotnet new install Trax.Samples.Templates
dotnet new trax-server -n MyApp
