System.Workflow.ComponentModel Namespace

.NET Framework 4.5

Provides classes related to the Windows Workflow Foundation component model.

  Class Description
Public class Activity Obsolete. Represents the fundamental building block of workflows. Activity is the base class for all activities.
Public class ActivityBind Obsolete. Binds an activity's property to a property, field, indexer, method, event, or another activity's property. This class cannot be inherited.
Public class ActivityChangeAction Obsolete. Represents a proposed change to a CompositeActivity within a running workflow instance. This class must be inherited.
Public class ActivityCollection Obsolete. Models a strongly typed ICollection of type Activity.
Public class ActivityCollectionChangeEventArgs Obsolete. Represents the information needed by an event handler to perform custom processing whenever the contents of an ActivityCollection changes.
Public class ActivityCondition Obsolete. Represents an abstract class for an expression, which evaluates to a Boolean. This class must be inherited.
Public class ActivityExecutionContext Obsolete. Represents the execution environment of an Activity. This class cannot be inherited.
Public class ActivityExecutionContextManager Obsolete. Allows a CompositeActivity to create and manage execution contexts for its child activities. This class cannot be inherited.
Public class ActivityExecutionStatusChangedEventArgs Obsolete. Holds information relating to the change of execution status event for an Activity. This class cannot be inherited.
Public class AddedActivityAction Obsolete. Represents a proposed addition of an Activity to a CompositeActivity within a running workflow instance.
Public class AlternateFlowActivityAttribute Obsolete. Custom attribute which indicates that the activity supports an alternative flow. This class cannot be inherited.
Public class CancellationHandlerActivity Obsolete. Represents cancellation logic that can be associated with a CompositeActivity. This class cannot be inherited.
Public class CompensatableTransactionScopeActivity Obsolete. Defines a compensatable version of the TransactionScopeActivity activity. This class cannot be inherited.
Public class CompensateActivity Obsolete. Triggers the compensation of a completed child Activity that implements the ICompensatableActivity interface. This class cannot be inherited.
Public class CompensationHandlerActivity Obsolete. Specifies workflow logic that undoes, or compensates for, the successful execution of the associated CompositeActivity. This class cannot be inherited.
Public class CompositeActivity Obsolete. Derivative of Activity that is the base class for all activities that contain other activities. A CompositeActivity is responsible for managing the execution of its child activities.
Public class DependencyObject Obsolete. The base class for all objects that have dependency properties. This class must be inherited.
Public class DependencyProperty Obsolete. A special kind of property that can be defined or attached to a DependencyObject. There are three kinds of dependency properties: instance properties, meta properties, and attached properties. This class cannot be inherited.
Public class FaultHandlerActivity Obsolete. Represents the activity class used to handle an Exception of the type specified by the FaultType property. This class cannot be inherited.
Public class FaultHandlersActivity Obsolete. Represents a CompositeActivity that has an ordered list of child activities of type FaultHandlerActivity. This class cannot be inherited.
Public class PersistOnCloseAttribute Obsolete. Indicates that the current workflow instance must be persisted when the adorned activity completes its execution. This class cannot be inherited.
Public class PropertyMetadata Obsolete. Represents the behavior of a dependency property.
Public class QueueEventArgs Obsolete. Represents the event arguments for a workflow queue-related event.
Public class RemovedActivityAction Obsolete. Represents a proposed removal of an Activity from a CompositeActivity within a running workflow instance.
Public class SuspendActivity Obsolete. Suspends the running workflow instance when executed. This class cannot be inherited.
Public class SynchronizationScopeActivity Obsolete. Represents a section of workflow that requires controlled access to shared variables. If two or more instances of a SynchronizationScopeActivity access the same variables, then the execution of these activities is effectively serialized. This class cannot be inherited.
Public class TerminateActivity Obsolete. Terminates the running workflow instance when an abnormal situation occurs. This class cannot be inherited.
Public class ThrowActivity Obsolete. Models the throwing of an exception. This class cannot be inherited.
Public class TransactionScopeActivity Obsolete. A section of workflow which demarcates a transaction boundary. A new Transaction is started when this Activity begins executing and the transaction commits when the Activity closes successfully. This class cannot be inherited.
Public class WorkflowChangeAction Obsolete. An abstract base class from which all classes that represent proposed changes to a running workflow instance must derive.
Public class WorkflowChanges Obsolete. Represents a set of proposed changes to a running workflow instance.
Public class WorkflowParameterBinding Obsolete. A general-purpose class that represents a binding to a named parameter. This class cannot be inherited.
Public class WorkflowParameterBindingCollection Obsolete. Represents a KeyedCollection<TKey, TItem> of type WorkflowParameterBinding. This class may not be inherited.
Public class WorkflowTerminatedException Obsolete. Represents the Exception that is raised when a workflow is terminated. This class cannot be inherited.
Public class WorkflowTransactionOptions Obsolete. Container for workflow transaction type options. This class cannot be inherited.
  Interface Description
Public interface IActivityEventListener<T> Obsolete. Defines the interface for an object that listens for an event.
Public interface ICompensatableActivity Obsolete. Defines the interface required by an Activity that can be compensated.
Public interface IDynamicPropertyTypeProvider Obsolete. Provides a property type to the bind infrastructure. It is implemented by activities that contain a property of variable type, where the type can vary depending on other activity settings.
Public interface IStartWorkflow Obsolete. Defines a service that can be obtained from an ActivityExecutionContext for the purpose of starting a new workflow instance.
Public interface IWorkflowChangeDiff Obsolete. Supports mining of workflow changes.
  Delegate Description
Public delegate GetValueOverride Allows a custom override of the GetValue logic associated with a dependency property that is defined on a dependency object.
Public delegate SetValueOverride Allows a custom override of the SetValue logic associated with a dependency property that is defined on a dependency object.
  Enumeration Description
Public enumeration ActivityCollectionChangeAction Obsolete. Represents an enumeration of the permissible actions which may be performed on an ActivityCollection, which typically represents the collection of all child activities of a CompositeActivity.
Public enumeration ActivityExecutionResult Obsolete. Enumeration of activity result values that qualifies the state of an Activity that has an ActivityExecutionStatus of Closed.
Public enumeration ActivityExecutionStatus Obsolete. Enumeration of activity status values that correspond to the life cycle of an activity within a running workflow instance.
Public enumeration DependencyPropertyOptions Obsolete. Represents an enumeration of DependencyProperty options.
