Question

The example given on this website working properly following is the link https://blogs.msdn.microsoft.com/brunoterkaly/2012/02/28/node-js-a-chat-server-written-in-node-and-a-client-app-written-in-c/#comment-12985
but when i am trying to implement this client app in uwp template .
issues are coming in Tcpclient , NetworkStream and some other classes which are not available in uwp.

Answer 1

The chat client in the blog you posted here is a WPF project, not a uwp app project. Classes like TcpClient and NetworkStream under System.Net.Sockets namespace are not supported in uwp.
In uwp we use classes under Windows.Networking.Sockets namespace instead, E.g.StreamSocket, StreamSocketListener and so on. More details please refence the sockets official documents in uwp. And the uwp official sample about sockets is here.
I also helped you transferred the chat client in the blog from wpf to uwp, you can directly download it from GitHub for further testing.
Parts of the code for uwp chat client:
private async void cmdConnect_Click(object sender, RoutedEventArgs e)
{
AddPrompt();
Windows.Networking.HostName serverHost = new Windows.Networking.HostName("127.0.0.1");
await tcpClient.ConnectAsync(serverHost, "8000");
serverStream = tcpClient.OutputStream.AsStreamForWrite();
StreamWriter writer = new StreamWriter(serverStream);
string request = txtChatName.Text.Trim() + " is joining";
await writer.WriteLineAsync(request);
await writer.FlushAsync();
Stream streamIn = tcpClient.InputStream.AsStreamForRead();
StreamReader reader = new StreamReader(streamIn);
string response = await reader.ReadLineAsync();
}
