System.Activities.Hosting Namespace

Provides classes related to hosting.

Classes

BookmarkInfo

Represents information about a named Bookmark.

BookmarkScopeInfo

Contains identification and initialization information about a BookmarkScope object.

LocationInfo

Provides information about a related Location.

SymbolResolver

SymbolResolver is an extension for providing a host LocationReferenceEnvironment containing objects that can be dereferenced by a string name. Values provided through a SymbolResolver are not persisted. Persistence of SymbolResolver values is a host responsibility.

WorkflowInstance

WorkflowInstance is a lightweight, per-instance runtime for executing a workflow program. It can be constructed to create a new workflow instance or from existing instance state. The APIs that WorkflowInstance.WorkflowInstanceControl exposes are the minimal set of runtime controls from which higher level operations can be implemented. This API set represents the entire breadth of functionality of the runtime. WorkflowInstance is an abstract class and relies on a host’s implementation of its abstract methods in order to provide host functionality such as synchronization, persistence, tracking, and extensions.

WorkflowInstanceExtensionManager

Manages a collection of extensions for a WorkflowInstance.

WorkflowInstanceProxy

A class that allows IWorkflowInstanceExtension extensions access to the workflow service host.

Structs

WorkflowInstance.WorkflowInstanceControl

Provides methods for WorkflowInstance derived classes to access the functionality of the workflow runtime.

Interfaces

IWorkflowInstanceExtension

This interface is implemented by composite extensions, or extensions that need access to the workflow instance. Implementers of this interface will be called by the WorkflowInstance prior to execution in order to provide additional extensions, or get access to the WorkflowInstance through the WorkflowInstanceProxy.

Enums

WorkflowInstanceState

Specifies the state of a WorkflowInstance.
