Exempel
protected override SecurityToken GetTokenCore(TimeSpan timeout)
{
// Create a SamlSecurityToken from the provided assertion

// Create a SecurityTokenSerializer that will be used to serialize the SamlSecurityToken

// Create a memory stream to write the serialized token into
// Use an initial size of 64Kb
MemoryStream s = new MemoryStream(UInt16.MaxValue);
// Create an XmlWriter over the stream
XmlWriter xw = XmlWriter.Create(s);
// Write the SamlSecurityToken into the stream
ser.WriteToken(xw, samlToken);
// Seek back to the beginning of the stream
s.Seek(0, SeekOrigin.Begin);
// Load the serialized token into a DOM
XmlDocument dom = new XmlDocument();

// Return a GenericXmlToken from the XML for the SamlSecurityToken, the proof token, the valid from

GetTokenCore När metoden åsidosättas och säkerhetstoken som skickas till tokenparametern inte kan hämtas utlöser du undantagetSecurityTokenException.
Metoden GetToken anropas av ClientCredentials klassen när en klient skickar ett SOAP-meddelande och en säkerhetstoken krävs.
Metoden GetToken anropar GetTokenCore metoden.
