Runtime Services

The workflow runtime engine supports the concept of external services. Services are class instances that you create and register with the runtime during application startup. Each service fulfills a defined purpose. Services come in two varieties: core and local. The functionality provided by core services is defined by Microsoft. In some cases, the workflow runtime will register its own default implementation of a core service if you don’t provide your own.

Runtime Engine

WF includes a core runtime engine that is represented by the WorkflowRuntime class (found in the System.Workflow.Runtime namespace). The workflow runtime is not a self-contained application. Instead, an instance of this class must be hosted by your application in order to execute and manage workflows. You host the workflow runtime and the runtime hosts the individual workflow instances. The workflow runtime is the component that provides an execution environment for the workflow instances.
