System.ServiceModel.Activities Namespace

Initializes the associated CorrelationHandle with a callback correlation.

Represents settings that define operational characteristics of a channel cache.

Initializes the associated CorrelationHandle with a .NET Context Exchange-based correlation, subject to the ContextExchangeMechanism specified.

Associates activities together in a correlation by representing a particular shared InstanceKey or transient context in the workflow.

An abstract base class for correlation initializers that are used to tell the runtime what protocol is being used for the correlation.

Provides implicit CorrelationHandle management for child messaging activities.

Used mainly to associate a concrete implementation of the InstanceStore such as SqlWorkflowInstanceStore with a workflow service host. This class is also used to add instance owner metadata.

Represents settings that define operational characteristics of a host.

Initializes correlation without sending or receiving a message.

Represents a message context.

Initializes the associated CorrelationHandle based on the results of the MessageQuerySet when the message is sent or received.

An activity that receives a message.

An abstract base class for classes that represent the data received by a workflow service.

A class used to receive a Message or a message contract type within a workflow service.

Enables a workflow service to receive data in the form of parameters .ReceiveParametersContent is interoperable with non-workflow WCF clients and services. The Parameters collection is similar to the argument declaration on a C# method signature. The Parameters collection cannot contain arguments marked with MessageContractAttribute, or of type Message. Use ReceiveMessageContent for these types of data. This is a sealed class.

An activity that receives a message as part of a request/reply message exchange pattern.

Represents the settings for an activity that receives a message.

Initializes the associated CorrelationHandle based on the RequestContext that is created for the two-way operation.

An activity that sends a message to a service.

An abstract base class for classes that represent the data sent to a workflow service.

Represents an extension that enables the customization of the cache sharing levels, the settings of the channel factory cache, and the settings of the channel cache for workflows that send messages to service endpoints using Send messaging activities.

A class used to send a single item (message) to or from a workflow service. The item can be a built-in type such as primitive types, Message, or XElement; or an application-defined data contract, message contract, or XML serializable type.

Enables sending data to or from a workflow service in the form of parameters.

An abstract class that defines extension methods for the send/receive activities.

An activity that sends the reply message as part of a request/response message exchange pattern on the service side.

Represents the settings for an activity that sends a message.

An activity which scopes the lifetime of a transaction which is initiated by a received message. The transaction may be flowed into the workflow on the initiating message, or be created by the dispatcher when the message is received.

Allows a client to send control operations to a workflow service hosted with WorkflowServiceHost.

A standard endpoint that enables you to call control operations on workflow instances.

Represents a context that is set up during workflow activation using the workflow hosting endpoint to handle arguments, and receive workflow completion notifications.

An abstract implementation of ServiceEndpoint. Derive from this class to expose contracts that support workflow creation and bookmark resumption.

This class is used in conjunction with the WorkflowHostingEndpoint class. It is used for sending the response for a request/reply contract supported by a WorkflowHostingEndpoint implementation.

Enables you to create, configure, and access the properties of a workflow service.

Provides a host for workflows. Supports features like messaging activities, multi-instancing, and configuration.

Represents a service contract that defines a set of operations that allows a client to update workflow service hosted with WorkflowServiceHost.

Implements a callback to be executed when a service message is received by the Receive and ReceiveParametersContent activities.

An interface that implements a callback that is called just before a message is sent on the wire by the Send or SendParametersContent activities.

Represents a service contract that defines a set of operations that allow you to control workflow instances.

Represents a service contract that defines a set of operations that allow you to update workflow instances.

A class that represents the types of serializers available.
