I have difficulties connecting to my SQL Server Express edition.
The Server and its SQL Browser are both running and named pipes are enabled,
even if I am not sure why it would return such an error since I only try to connect to my localhost.
My connection string is currently:
Data Source=localhost\SQLEXPRESS;Integrated Security=True;Pooling=False
the initial catalog is not yet set, because I try to use the connection (System.Data.SqlClient.SQLConnection) to create a new database by ddl.
The resulting error is:
provider: Named Pipes-Provider, error: 40
Connection to SQL-Server could not be established
Any suggestion greatly appreciated.
