I get this error :
ora-06413 connection not open
The strange thing is that I can connect to the database from my C# code instead of using Server Explorer Tool.
What Kind of problem could it be ?

I've come accross a solution that worked for me. I had this problem with an .sdf file (SQL Server Compact Edition).
Close all instances of Visual Studio;
Edit %AppData%\Microsoft\VisualStudio\10.0\ServerExplorer\DefaultView.SEView (could be under '%AppData%\Roaming')and remove the connection with the wrong Provider. If you do not know which of the provider is failing, simply delete the file
Open Visual Studio and try to open your .mdf or .sdf file
