Windows Support for WCF

Install the Windows Identity Foundation (WIF) SDK

The WIF SDK has a number of samples showing how WIF and WCF interact. In particular:

Simple Claims Aware Web Service:
This sample shows how claims are enumerated in a relying party Web service (WCF based). It uses a WCF based security token service that is an IIS hosted WCF service.

Federation for Web Services:
This sample shows how to build STSes that are WCF-based and hosted in IIS and using WSFederationBinding how one can achieve federation scenario.

Identity Delegation:
The Identity Delegation Scenario sample shows how to build identity delegation into simple distributed services by using the ActAs functionality. This project contains a mix of passive and active STS. SAML 1.1 tokens are being issued by STSes. The service projects are console based and the client is browser.

The Identity Developer Training Kit has labs for Web Services and Identity for Visual Studio 2010 Developers.
