Download and Install WCF Data Services and OData Libraries

NuGet Packages

WCF Data Services now ships separately from the .NET Framework. The official binaries are distributed through NuGet, a package management platform for .NET applications.

WCF Data Services Server (Microsoft.Data.Services) WCF Data Services provides a fully-featured server API for responding to OData queries and consuming/producing OData payloads. This NuGet package provides a server implementation of OData v3.

WCF Data Services Client (Microsoft.Data.Services.Client Similar to the server API, WCF Data Services provides a robust client API for consuming OData services. The client API also has an embedded LINQ provider to simplify construction of OData queries. This NuGet package provides a client framework that is capable of consuming OData v3 services.

ODataLib (Microsoft.Data.OData) ODataLib is a low-level library optimized for serializing and deserializing OData streams. ODataLib is one of the fundamental building blocks used in WCF Data Services, Web API and other OData-enabled platforms.

EdmLib (Microsoft.Data.Edm) EdmLib is a low-level library optimized for serializing and deserializing Entity Data Models (EDM). EdmLib is one of the fundamental building blocks used in WCF Data Services, Web API and other OData-enabled platforms.

data.js data.js is a cross-browser JavaScript library that enables data-centric Web applications by leveraging modern protocols such as JSON, OData and HTML5-enabled browser features. data.js currently has support for OData v2 and is currently being upgraded to provide support for OData v3.

Tooling Installers

The Add Service Reference experience in Visual Studio makes it very easy to generate proxy classes for calling OData services. Tooling for Visual Studio 2012 adds a reference to the appropriate NuGet packages.

	Windows Store Apps The WCF Data Services tooling for Windows Store apps enables developers to generate
	Windows Phone 7 (Visual Studio 2010) The Windows Phone 7 SDK has native support for building OData clients.
