X509WindowsSecurityToken Class
Represents a security token that is based upon an X.509 certificate and that the certificate is mapped to a Windows domain user or local computer user account.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
Typically, application developers do not need to use the X509WindowsSecurityToken class, unless a Web service must gain access to details about a X.509 certificate referenced in an incoming SOAP message or the domain or computer account that the certificate is mapped to. To get the details of the X.509 certificate, access the Certificate property. To get the user identity, see the WindowsIdentity property.
