When trying to change default database it fails because connection is not open

[JamesHorsley]

In this below the call to cn.ChangeDatabase fails because the connection is not yet open - it needs moving to after the cn.Open()

try
                {
                    if (!database.Equals("master", StringComparison.InvariantCultureIgnoreCase))
                    {
                        cn.ChangeDatabase(database);
                    }

                    var sqlBatch = string.Empty;
                    var cmd = new SqlCommand(string.Empty, cn);
                    cn.Open();
