Create Connection using ConnectionBuilder not working giving error.

[jitendrajadav]

In my Xamarin forms application I am trying to connect Zebra Printer using IPAddress and Port but it couldn't connect getting error like below

My code is like this ;

` IConnection connection = null; try { connection = ConnectionBuilder.Current.Build("192.168.137.10:9100"); connection.Open(); IZebraPrinter printer = ZebraPrinterFactory.Current.GetInstance(connection); if ((!CheckPrinterLanguage(connection)) || (!PreCheckPrinterStatus(printer))) { return; }

            connection.Write(GetBytes(header));
        }
        catch (Exception ex)
        {
            // Connection Exceptions and issues are caught here            
        }

`

Error :

I have the same problem with using LinkOS.Plugin Zebra nugget package

Don't use the LinkOS.Plugin. We should be using the Zebra.Printer.SDK v2.15.2634 package, which can be found in the NuGet Package Manager for your Xamarin project.
