Question

我将Visual Studio中的项目和数据库SQL SERVER上传到IIS服务器。配置：

LocalSqlServer：服务器= N-PC \ SQLEXPRESS;数据库=其余；集成安全性= true

RestEntities：“元数据= res：// /RestEntities.csdl|res:// /RestEntities.ssdl|res://*/RestEntities.msl;provider=System.Data.SqlClient ; provider connection string =“ data source = N-PC \ SQLEXPRESS; initial catalog = Rest; integrated security = True; MultipleActiveResultSets = True; App = EntityFramework”“ providerName =” System.Data.EntityClient“

我在IIS配置中看到的错误是： “ ExceptionMessage”：“应用程序的配置文件中的连接字符串'RestMarketEntities'不包含必需的providerName属性。\”“

我是否需要在IIS服务器的“ providers”目录和“连接字符串”文件夹中设置PROVIDER NAME？
- 我是否需要更改代码中的某些内容才能使其在IIS服务器上运行？
IIS中的连接字符串应该与代码中显示的完全相同吗？

谢谢

错误：

如何在IIS服务器上的配置中定义提供者名称？
