建立与SQL Server实例'.\SQLEXPRESS'的连接时发生错误。 [英] An error occurred while establishing a connection to SQL Server instance '.\SQLEXPRESS'.

问题描述

刚刚安装了Beta 2，将其启动并选择了远程数据选项，以便使用SQL Client从另一台服务器中获取数据。 表模式在设计器中显示没有问题，添加了一个屏幕和已编译的项目，并显示消息"在建立
a连接到SQL Server实例时出错"。\ SQLEXPRESS'。" 

Just installed Beta 2, brought it up and selected the remote data option to get data out of another server using SQL Client.  Table schema showed in designer no problem, added a screen and compiled project and the message "An error occurred while establishing a connection to SQL Server instance '.\SQLEXPRESS'." 

我确定它与LS的内部有关，但实际上，我甚至不想连接到本地实例，所以这有什么用呢？

I'm sure it has something to do with internals of LS, but really, I didn't even want to connect to local instance so what's up with this?

建议相关。

OutputDirectory = " Bin \Data "

< span style ="color：red"> SqlExpressInstanceName = "

(MSBuildProjectFullPath)" OutputDirectory="Bin\Data" SqlExpressInstanceName="

（SqlExpressInstanceName） "

ExternalDataSources = " @（ServerExternalDataSources） " />

(SqlExpressInstanceName)" ExternalDataSources="@(ServerExternalDataSources)"/>
