1.
sqlserver2k 必须安装sp4补丁 （2005未测试）
否则使用SqlWorkflowPersistenceService 和SqlWorkflowTrackingService时会报错

2.
web.config 添加配置
<WorkflowRuntime Name="WorkflowServiceContainer">
<CommonParameters>
<add name="ConnectionString" value="Initial Catalog=SharedStore;Data Source=localhost;Integrated Security=SSPI;"/>
</CommonParameters>
<Services>
<add type="System.Workflow.Runtime.Hosting.ManualWorkflowSchedulerService, System.Workflow.Runtime, Version=3.0.00000.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
<add type="System.Workflow.Activities.ExternalDataExchangeService, System.Workflow.Activities, Version=3.0.00000.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
<add type="System.Workflow.Runtime.Hosting.SharedConnectionWorkflowCommitWorkBatchService, System.Workflow.Runtime, Version=3.0.00000.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add type="System.Workflow.Runtime.Hosting.SqlWorkflowPersistenceService, System.Workflow.Runtime, Version=3.0.00000.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35" UnloadOnIdle="true"/>
<add type="System.Workflow.Runtime.Tracking.SqlTrackingService, System.Workflow.Runtime, Version=3.0.00000.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
</Services>
</WorkflowRuntime>
即可以使用类似
SqlWorkflowPersistence persist = runtime.GetService<SqlWorkflowPersistence>();
的方法获取Service
要不然只能通过如此冗长的方式
SqlWorkflowPersistence persist = new SqlWorkflowPersistence (
connectionString,UnloadOnIdle,timeSpan,timeSpan);
添加
<add name="WorkflowHost" type="System.Workflow.Runtime.Hosting.WorkflowWebHostingModule, System.Workflow.Runtime, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
到 <httpModules></httpModules> 节
3.
当persistenceService 和trackingService使用在同一个数据库里时
必须添加SharedConnectionWorkflowCommitWorkBatchService
4.
新建工作流程Service时必须添加[ExternalDataExchange]Attribute
wwf与host通信时使用的class必须添加[Serializable],可供序列化
5.
asp.net环境下使用ManualWorkflowSchedulerService 默认单进程
使用scheduler.RunWorkflow(instanceId)驱动工作流程
