51Degrees Geo-Location Engines

51Degrees Pipeline API

Developer Documentation


This repository contains engines for the .NET implementation of the Pipeline API that provide location services. Currently, reverse geocoding is supported through the 51Degrees cloud service.


Visual Studio 2019 or later is recommended. Although Visual Studio Code can be used for working with most of the projects.

The Pipeline engines are written in C# and target .NET Standard 2.0.3 Test and example projects target .NET Core 2.1 or 3.1.
