I am building a Windows UWP app in Visual Studio which is running on a Raspberry Pi 3B. From this I would like to shutdown / reboot another Raspberry Pi running Raspbian.
Is that possible and how?
Thank you in advance

Yes, it is possible. You can use a SSH client such as Chilkat.Ssh or Asmodat.Standard.SSH.NET in UWP app to connect to the Raspbian, and then send the shutdown/reboot command( e.g.sudo shutdown –h now) to it. Asmodat.Standard.SSH.NET if a free library, but Chilkat.Ssh is not. You can find some other SSH libraries which could support .Net Standard 2.0/UAP 10.

Update:

The following code snippet is with using Asmodat.Standard.SSH.NET library. It works in my UWP app run on Windows IoT Core.

C#:

    private async void ButtonReboot_Click(object sender, RoutedEventArgs e)

    {

        await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal,  async () =>

        {

            using (var client = new SshClient("xxx.xxx.xxx.xxx", "xx", "xxxxxxx"))

            {

                client.Connect();

                var command = client.CreateCommand("sudo reboot -f");

                var asyncResult = command.BeginExecute();

                var reader = new StreamReader(command.OutputStream);



                while (!asyncResult.IsCompleted)

                {

                    await reader.ReadToEndAsync();

                }



                command.EndExecute(asyncResult);



                client.Disconnect();

            }

        });

    }

VB.NET

Private Async Sub ButtonReboot_Click(sender As Object, e As RoutedEventArgs)



    Await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal,

            Async Sub()

                Using sClient = New SshClient("XXX.XXX.XXX", "XX", "XXXX")

                    sClient.Connect()

                    If sClient.IsConnected Then

                        Dim sCommand = sClient.CreateCommand("sudo reboot -f rn")

                        Dim asyncResult = sCommand.BeginExecute()

                        Dim reader = New StreamReader(sCommand.OutputStream)



                        While Not asyncResult.IsCompleted

                            Await reader.ReadToEndAsync()

                        End While



                        sCommand.EndExecute(asyncResult)



                        Debug.WriteLine("Reboot")

                        sClient.Disconnect()

                    End If

                End Using

            End Sub)



End Sub
