.net - .NET在三个 namespace 中的声明

Question

现在，这很奇怪。在完成对.NET中基于声明的解决方案的研究之后，发现不同的作者在实际谈论同一问题时会引用.NET namespace 中的不同类。声明类(更不用说其他的Identity，Principal，Manager，Helper类)在3个不同的命名空间中定义。

很明显，WIF是.NET 3.5和4.0的单独附加组件，并且它已被重写并成为4.5的核心组成部分。但是，这对于确定用于新项目的类的明确指示确实有帮助(这样可以更轻松地将端口移植到4.5)。还有其他人对此主题有更多信息吗？

Answer 1

对于仍在寻找最终答案的任何人，MSDN的System.IdentityModel.Claims Namespace页面上都有以下信息...

The System.IdentityModel.Claims namespace contains classes thatimplement the Windows Communication Foundation (WCF) claims-basedidentity authorization model. This model includes the Claim class andthe ClaimSet class.

Beginning with .NET Framework 4.5 and theintegration of Windows Identity Foundation (WIF) into the .NETFramework, the WCF claims-based identity model has been superseded byWIF. WIF provides a claims-based identity object model that can beused to provide authentication and authorization across severalMicrosoft product stacks, including the CLR, WCF, and ASP.NET. The WIFclasses that represent claims, claim types, and identities andprincipals that are based on claims are contained in theSystem.Security.Claims namespace. Beginning with .NET 4.5, theseclasses should be used instead of those in theSystem.IdentityModel.Claims namespace.
