WorkflowRuntime Class

Represents the configurable execution environment provided by the workflow runtime engine for workflows.

Namespace:  System.Workflow.Runtime
Assembly:  System.Workflow.Runtime (in System.Workflow.Runtime.dll)

'Declaration
Public Class WorkflowRuntime _
	Implements IServiceProvider, IDisposable
'Usage
Dim instance As WorkflowRuntime

WorkflowRuntime exposes functionality required by a host application and services to configure and control the workflow runtime engine and to be notified of changes to both the workflow runtime engine and any of its workflow instances.

The following code example demonstrates how you can use WorkflowRuntime functionality from a workflow host. It provides examples of how to use the WorkflowRuntime constructor and the AddService, StartRuntime, and StopRuntime methods. The code also shows the recommended method to create a WorkflowInstance object in a workflow host using the CreateWorkflow method. It also shows how to set event handlers for the WorkflowCompleted, WorkflowIdled, and WorkflowTerminated events.

This code example is part of the Canceling a Workflow SDK Sample from the Program.cs file. For more information, see Canceling a Workflow.

Shared Sub Main()
    Dim connectionString As String = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;" 
    Using workflowRuntime As New WorkflowRuntime()
        Dim dataService As New ExternalDataExchangeService()
        workflowRuntime.AddService(dataService)
        dataService.AddService(expenseService)

        workflowRuntime.AddService(New SqlWorkflowPersistenceService(connectionString))


        AddHandler workflowRuntime.WorkflowCompleted, AddressOf OnWorkflowCompleted
        AddHandler workflowRuntime.WorkflowTerminated, AddressOf OnWorkflowTerminated
        AddHandler workflowRuntime.WorkflowIdled, AddressOf OnWorkflowIdled
        AddHandler workflowRuntime.WorkflowAborted, AddressOf OnWorkflowAborted
