As the error indicates, your application cannot find the SQL Server you are trying to connect to. Are you running this from the same machine as your debug environment (i.e. the machine where you have Visual Studio installed)? Are you connecting to a local or remote SQL Server? Are there any firewalls, proxy servers, or anything else between you and the SQL Server?
