WindowsClaimsPrincipal 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.]

The WindowsClaimsPrincipal class extends the WindowsPrincipal class to carry Claim information in addition to the identity information drawn from Windows security tokens.

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


Dim instance As WindowsClaimsPrincipal


<SerializableAttribute> _
Public Class WindowsClaimsPrincipal
    Inherits WindowsPrincipal
    Implements IClaimsPrincipal, IPrincipal, IDisposable
public class WindowsClaimsPrincipal : WindowsPrincipal, IClaimsPrincipal, IPrincipal, IDisposable
public ref class WindowsClaimsPrincipal : public WindowsPrincipal, IClaimsPrincipal, IPrincipal, IDisposable
/** @attribute SerializableAttribute() */ 
public class WindowsClaimsPrincipal extends WindowsPrincipal implements IClaimsPrincipal, IPrincipal, 
public class WindowsClaimsPrincipal extends WindowsPrincipal implements IClaimsPrincipal, IPrincipal, 


In the claims model, multiple users or claims-based identities can be party to a single action. This class extends the WindowsPrincipal class to enable a Windows execution context to carry multiple claims-based identities (WindowsClaimsIdentity). WindowsClaimsPrincipal exposes a collection of identities, each of which implements IClaimsIdentity. In the common case, there will be a single issuer and a single token and the identities collection will only have one element. However, it is possible in advanced scenarios for a relying party to ask (via policy) for more than one security token, potentially from different issuers.
