Assembly: System.IdentityModel (in system.identitymodel.dll)
Typically, the X509IssuerSerialKeyIdentifierClause is not used, other than when a custom security token service is created. When a security token service returns a security token, the issued security token contains references to attached and unattached security. Attached references refer to security tokens that are contained within the security header of a SOAP message and unattached references are security tokens that are not included within the security header of a SOAP message. These references typically affirm the authenticity of the issued security token. Use the X509IssuerSerialKeyIdentifierClause class to reference a X509SecurityToken security token using the distinguished name of the certificate issuer and the X.509 certificate's serial number. The IssuerName and IssuerSerialNumber properties represent the distinguished name of the certificate issuer and the X.509 certificate's serial number, respectively.
Windows Communication Foundation (WCF) supports the following types of security token references for X509SecurityToken security tokens.
