Xamarin Can't Connect to SQL Database

Question

I have a C# Xamarin Android application which I need to connect to a SQL Server instance accessible over the network.

try
{
      using (SqlConnection cn = new SqlConnection(ConnectionString))
      {
                cn.Open();

                IsConnected = true;
       }
  }
  catch (Exception ex)
  {
        Toast.MakeText(Application.Context, "Error Occuerred: " + ex.Message, ToastLength.Long).Show();
   }

The Connection String is as follows: Data Source=IPAddress;Initial Catalog=DatabaseName;Persist Security Info=True;User ID=SomeUser;Password=SomePassword

I have included the INTERNET and WIFI_State Permissions in the manifest. (To check if wifi is currently turned on and connected to some kind on network)

I am getting an error: Server Does Not Exist or Connection is refused. I can connect my Honeywell Scanning device to the database with the same connection string.

Please NOTE I don not want a web service to handle the SQL connection in order for me to select and update tables.

Answer 1

Wrote an ASP. NET web service which is very efficient and quick
