Octokit is a suite of client libraries designed for interacting with the GitHub API, with the latest addition being Octokit.net for .NET developers. This new library is used in GitHub for Windows and offers an asynchronous API through HttpClient, requiring .NET 4.5 or later. It is accessible via NuGet, and there is also an IObservable-based companion package, Octokit.Reactive, for those who prefer Reactive Extensions (Rx). The release follows the earlier introduction of Octokit libraries for Ruby and Objective-C, expanding the tools available for developers working with GitHub's API.
