Question

我正在尝试从lightswitch连接到sql2008 express。我尝试了一个简单的表单，但每次我尝试保存时，都会收到此错误：

底层提供商在Open上失败   内部异常消息：
  由于启动用户实例的进程失败，无法生成SQL Server的用户实例。连接将被关闭。

我检查了SQL日志，下面是我得到的错误：

我检查了SQL Server代理（SQLExpress），并在发生错误后关闭它。

我正在运行VS-2010，在Win7 64位上使用SQL 2008和SQL 2008 Express。

Answer 1

我怀疑这与我遇到的问题类似。我安装了Visual Studio而没有安装SQL Server Express，因为我已经在我的开发计算机上安装了SQL Server 2008。后来我安装了SQL Server Express，但是我无法让Lightswitch完全按照你描述的方式工作。我删除了两个版本的SQL Server。之后重新安装的SQL Server Express和Lightswitch正常工作。我没有再次重新安装SQL Server 2008。我正在网络上使用真正的服务器进行这项工作。
