Hi,
Today, I have met with following problem. I'm trying add new .mdf file to App_Data folder in my ASP.NET Web Application and I get this information:
"Connections to SQL Server database files (.mdf) require SQL Server 2005 Express or SQL Server 2008 Express to be installed and running on the local computer. The currnet version of SQL Server Express can be downloaded at url [link].."
Have any idea? I've got SQL Server 2014 (working) and I'm using Visual 2013 Proffesional Update 4.
