通过Web.config在WorkflowServices中的持久性 [英] Persistence in WorkflowServices via Web.config

问题描述

我对工作流程服务的BETA 2的持久性有疑问.我有一个实现关联的工作流服务，并且可以完美地工作，直到在web.config中放入以下行:

<

I'm having a problem with persistence in BETA 2 for a workflowservice.  I have a workflowservice that implements correlation and works perfectly UNTIL I put the following line in the web.config:

<

sqlWorkflowInstanceStore connectionString 数据源=.\ SQLEXPRESS;初始目录= InstanceStore;集成安全性= True "

sqlWorkflowInstanceStore connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=InstanceStore;Integrated Security=True"/>

 

当我将该行放入时，会出现以下错误:

已经添加了具有相同键的项.

When I put that line in, I get this error:

An item with the same key has already been added.

推荐答案

碰碰...有人吗?谁在做托管在IIS中的WorkflowServices的持久化?我错过了一些设置吗?我找不到关于此的任何文档-非常令人沮丧！

Bump...anyone?  Who's doing persistence of WorkflowServices hosted in IIS?  Is there some setup that I missed?  I cannot find any doc on this - so frustrating!!
