The goal of this whitepaper is to help developers get started building claims-aware applications using the Microsoft© Code Name “Geneva” Framework. In this paper, I introduce concepts and terminology to help developers understand the benefits and concepts behind the claims-based model of identity. My target audience does not consist of security experts, but rather those familiar with ASP.NET or Windows Communication Foundation (WCF) programming, and who are building web applications or services that care about authentication and authorization. As such, my focus will be on building relying parties using the Geneva Framework. I will talk about issuance and security token services (STS) and will provide an example of an STS
built using the Geneva Framework. However, that is not the focus of this paper.
