You can simply build console app to test. Console app sample: namespace DatabaseConnectionTester { using System; using System.Data.Common; using System.Data.SqlClient; internal static class Program { private static int Main( string [] args) { bool result; if (args.Length == 0) { result = true ; } else { try { var connectionString = "Connect Timeout=10;Pooling=false;Integrated Security=sspi;server=" + args[0]; using (var connection = new SqlConnection(connectionString)) { connection.Open(); result = true ; } } catch (DbException) { result = false ; } if (args.Length > 1) { Console.WriteLine(result); } } return Convert.ToInt32(result); } } }

You can provide connection string into configuration and check connection based on application. Also you can set time-out in connection string. Connection test function. //connection string sample: Server=.;Initial Catalog=;Persist Security Info=False;User ID=userName;Password=YourPassword;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=true;Connection Timeout=300000; public bool TryOpenConnection( string connectionString) { try { var conn = new SqlConnection(connectionString); conn.Open(); connection = conn; return true ; } catch (exception) { connection = null ; return false ; } }

each database has a connection property we call it connection string , which includes server name , database name and username and password (Authentication details if any otherwise windows authentication) , we specify the connection string in the application. so each application having the same connectionstring will point to same database.
