Adding .mdf file in Visual studio
When I add .mdf file in my project, the error is "the user instance login flag is not supported on this version of SQL Server. The Connection will be closed". I find out the solutions on the Internet. They says that update from tools option for SQL server. Although I updated, the error still happen. And then, I configured "user instance=false" in C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config. That is not the point to be solve my error.
Plz give me some advice
