RestSharp is a simple to use REST client library for .NET

RestSharp takes the pain out of calling REST services from .NET. This library takes care of the quirks in .NET's HTTP classes, handles deserialization cleanly, simplifies making asynchronous calls, and just makes it really easy to implement calls to REST services from inside your application.

RestSharp comes with a built-in JSON serializer. The default serializer has been compatible with the Json.NET project but this compatibility has been given up since release 100.3.

Installation Installing RestSharp can most easily be done using its NuGet package:

Install-Package RestSharp
