Windows Identity Foundation
Introduction '''Windows Identity Foundation''' ('''WIF''') is a Microsoft software framework for building identity-aware applications. It provides APIs for building ASP.NET or WCF based security token services as well as tools for building claims-aware and federation capable applications.Windows Identity Foundation is supported on IIS 6/Windows Server 2003, IIS 7/Windows Vista, Windows Server 2008 and Windows 7.Version 1.0 shipped as a standalone product, but the product is now included as a part of Microsoft .NET Framework v4.5.
Major features WIF has the following major features:* It allows developers to build claims-aware applications by providing a set of application programming interfaces (APIs) that help developers write code to make access decisions to applications based on claims. * It provides templates to help developers get started building claims-aware applications. * It provides utilities that facilitate creation of a trust relationship between a claims-aware application (sometimes referred to as a Relying on Party application, or RP), and a Security Token Service (STS). * It provides a set of ASP.NET controls that help developers create web pages in claims-aware applications. * It includes a utility that helps developers translate between claims and NT tokens, so that claims-aware applications can be used to access resources that require NT-Token based identity. * It includes functionality that allows identities to be maintained across multiple service boundaries, and allows delegation of claims. * It provides tools to help developers build custom security token services using ASP.NET or WCF.
