using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Activities;
using System.ServiceModel.Activities;
using System.ServiceModel.Description;using System.Activities.DurableInstancing;
using System.Runtime.DurableInstancing;
using System.Activities.Persistence;
using System.ServiceModel.Activities.Description;
using System.Xml.Linq;namespace Host
{class Program{static void Main(string[] args){var host new WorkflowServiceHost(new DocumentReviewLib.DocumentReviewWorkflow(),new Uri(http://localhost:8080/DRS));host.AddDefaultEndpoints();//这个方法是添加了一些标准的端点host.Description.Behaviors.Add(new ServiceMetadataBehavior() { HttpGetEnabled true });var store new SqlWorkflowInstanceStore(server(local)\\sqlexpress;databaseWF4;integrated securitytrue);host.UnknownMessageReceived (o, e) {Console.WriteLine(\n e.Message \n);};host.Description.Behaviors.Add(new WorkflowIdleBehavior(){TimeToPersist TimeSpan.FromSeconds(0)});XNamespace xNS XNamespace.Get(http://xizhang.com/DocumentReview);store.Promote(DocumentReview,new ListXName() { xNS.GetName(TicketId) },null);host.WorkflowExtensions.Add(new Extensions.MyInstanceStoreParticpant());host.DurableInstancingOptions.InstanceStore store;host.Open();var common new ServiceHost(typeof(CommonService),new Uri(http://localhost:8080/Common));common.AddServiceEndpoint(typeof(ICommonService).FullName,new BasicHttpBinding(),);common.Open();Console.WriteLine(Server is ready.);Console.Read();}}[ServiceContract]public interface ICommonService{[OperationContract]int[] GetTicketIds();}public class CommonService : ICommonService{public int[] GetTicketIds(){var ctx new InstanceStoreDataContext();return ctx.DocumentReviewTasks.Select(r (int)r.TicketId).ToArray();}}}2. 修改之后的Host代码请大家比较一下有何区别using System;
using System.Collections.Generic;
using System.Linq;

using System.Activities.Persistence;
using System.ServiceModel.Activities.Description;
using System.Xml.Linq;namespace Host
{class Program{static void Main(string[] args){var host new WorkflowServiceHost(new WorkflowService() { ConfigurationName DocumentReviewLib.DocumentReviewWorkflow,Body new DocumentReviewLib.DocumentReviewWorkflow()});//这里可以通过进一步的Behavior定制来简化。此处略 XNamespace xNS XNamespace.Get(http://xizhang.com/DocumentReview);var store (SqlWorkflowInstanceStoreBehavior)host.Description.Behaviors.FirstOrDefault(b b.GetType() typeof(SqlWorkflowInstanceStoreBehavior));store.Promote(DocumentReview,new ListXName() { xNS.GetName(TicketId) },null);//这里可以通过进一步的Behavior定制来简化。此处略host.WorkflowExtensions.Add(new Extensions.MyInstanceStoreParticpant());host.Open();var common new ServiceHost(typeof(CommonService));common.Open();Console.WriteLine(Server is ready.);Console.Read();}}[ServiceContract]public interface ICommonService{[OperationContract]int[] GetTicketIds();}public class CommonService : ICommonService{public int[] GetTicketIds(){var ctx new InstanceStoreDataContext();return ctx.DocumentReviewTasks.Select(r (int)r.TicketId).ToArray();}}}3.添加的app.config文件内容?xml version1.0 encodingutf-8 ?
