ClaimsPrincipal 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.]

Represents a claims-based principal object.

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


Dim instance As ClaimsPrincipal


<SerializableAttribute> _
Public Class ClaimsPrincipal
    Implements IClaimsPrincipal, IPrincipal
public class ClaimsPrincipal : IClaimsPrincipal, IPrincipal
public ref class ClaimsPrincipal : IClaimsPrincipal, IPrincipal
/** @attribute SerializableAttribute() */ 
public class ClaimsPrincipal implements IClaimsPrincipal, IPrincipal
public class ClaimsPrincipal implements IClaimsPrincipal, IPrincipal


In the claims model, multiple users or claims-based identities can be party to a single action. The ClaimsPrincipal class exposes a collection of identities through the Identities property. Each of these identities implements the IClaimsIdentity interface and you can access the claims associated with the current caller through them. 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. For more information about using claims-based principal objects in Windows® Identity Foundation (WIF), see the IClaimsPrincipal class.
