ClaimTypeRequirement Class

Specifies the types of required and optional claims expected to appear in the federated credential.

Namespace:  System.ServiceModel.Security.Tokens
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class ClaimTypeRequirement

In a federated scenario, services state the requirements on incoming credentials. For example, the incoming credentials must possess a certain set of claim types. This requirement is manifested in a security policy. When a client requests a security token from a security token service (for example, CardSpace), it puts the requirements into a token request so that the security token service can issue the security token that satisfies the requirements accordingly.

The following code adds two claim type requirements to a security binding.

WSFederationHttpBinding binding = new WSFederationHttpBinding();
   (new ClaimTypeRequirement
   (new ClaimTypeRequirement
   ("", true));

The following config file is used with the preceding code.

    <binding name="myFederatedBinding">
      <security mode="Message">
        <message issuedTokenType="urn:oasis:names:tc:SAML:1.0:assertion">
            <add claimType=""
              isOptional="false" />
            <add claimType=""
              isOptional="true" />
