**OpenSleigh** is a distributed Saga management library, written in C# with .NET Core.
\
It is intended to be reliable, fast, easy to use, configurable, and extensible.

### What?

So what is a Saga exactly? The basic idea is quite interesting: in a micro-service architecture, it often happens that we need to manage several long-running operations that span multiple services.

A good example could be an Order processing workflow: in this scenario, you have to orchestrate multiple services, do inventory management, credit check, handle shipping, and so on.

**OpenSleigh** helps by taking care of [distributed transactions](https://www.davidguida.net/improving-microservices-reliability-part-1-two-phase-commit/), keeping track of the global status, and managing the whole flow.

For more details, check the Use Cases page.

### Installation

The Core module is available [on Nuget](https://www.nuget.org/packages/OpenSleigh).
\
However, Transport and Persistence packages are necessary to properly use the library.
