ClaimsIdentity Class

[Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework. The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

Implementation of a claims-based representation of a single user.

Namespace: Microsoft.IdentityModel.Claims
Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)


Dim instance As ClaimsIdentity


<SerializableAttribute> _
Public Class ClaimsIdentity
    Implements IClaimsIdentity, IIdentity, ISerializable
public class ClaimsIdentity : IClaimsIdentity, IIdentity, ISerializable
public ref class ClaimsIdentity : IClaimsIdentity, IIdentity, ISerializable
/** @attribute SerializableAttribute() */ 
public class ClaimsIdentity implements IClaimsIdentity, IIdentity, 
public class ClaimsIdentity implements IClaimsIdentity, IIdentity, 


The ClaimsIdentity class is a generic implementation of the IClaimsIdentity interface, which you can use directly, or derive from to implement your own representation of an identity in your claims-aware application. Windows® Identity Foundation (WIF) also exposes more specialized implementations IClaimsIdentity: the WindowsClaimsIdentity class represents a Windows user, and the RsaClaimsIdentity class represents a user authenticated using RSA SecurID authentication.
