System.IdentityModel Namespace

The System.IdentityModel namespace contains classes that are used to build security token services (STS). These include the SecurityTokenService and Scope classes, as well as exception several utility classes that provide the ability to perform cookie transforms.

Classes

AsynchronousOperationException

The exception that is thrown when an error occurs during an asynchronous operation.

AsyncResult

An abstract base class that implements the IAsyncResult interface. Serves as a base class from which to derive IAsyncResult objects that can be used for common asynchronous programming scenarios.

BadRequestException

The exception that is thrown when a token request (RST) is not understood by the security token service (STS).

CookieTransform

The abstract base class for classes that apply a reversible data transform to cookie data.

DeflateCookieTransform

Provides cookie compression using DeflateStream.

DelegatingXmlDictionaryReader

A class that wraps a specified reader and delegates all XmlDictionaryReader calls to the wrapped reader.

DelegatingXmlDictionaryWriter

A class that wraps a specified writer and delegates all XmlDictionaryWriter calls to the wrapped writer.

EnvelopedSignatureReader

Wraps a reader that is pointing to enveloped signed XML to provide a reader that can be used to read the content without having to process the signature. The signature is automatically validated when the last element of the envelope is read. This class cannot be inherited.

EnvelopedSignatureWriter

Wraps a writer and generates a signature automatically when the envelope has been completely written. This class cannot be inherited.

LimitExceededException

The exception that is thrown when a configured limit or quota is exceeded.

OpenObject

An abstract class that provides a generic property bag to derived classes.

ProtectedDataCookieTransform

Provides cookie integrity and confidentiality by using the ProtectedData class. This class cannot be inherited.

RequestException

The base class for exceptions thrown on request failures.

RequestFailedException

The exception that is thrown if the specified request (RST) failed due to an external reason that cannot be specifically determined.

RsaEncryptionCookieTransform

Encrypts a cookie using RSA.

RsaSignatureCookieTransform

Provides cookie integrity using an RSA signature.

Scope

Represents the configuration for the token issuance request.

SecurityMessageSerializationException

The exception that is thrown when an error occurs while serializing a security message.

SecurityTokenService

The abstract base class that defines the properties and methods of a security token service (STS).

SecurityTokenService.FederatedAsyncState

This class is used to maintain the request state across asynchronous calls within a security token service.

SignatureVerificationFailedException

The exception that is thrown when an error occurs while processing a signature

TypedAsyncResult<T>

A concrete implementation of AsyncResult that will wrap the result Type and return it when the End(IAsyncResult) method is called.

UnsupportedTokenTypeBadRequestException

The exception that is thrown when the specified token request (RST) is not understood because of an unknown token type.
