This is piece of code

using Fuse;
using Fuse.Scripting;
using Fuse.Reactive;
using Uno.UX;
using Uno.Text;
using Uno.Threading;
using Uno.Net.Sockets;

[UXGlobalModule]
public class MySocket : NativeEventEmitterModule
{
    static readonly MySocket _instance;
    public delegate void ShowValue();
    Socket socket;
    public MySocket()
        : base(true, "onMessageReceived", "onConnected", "onDisconnected", "onError")
    {
        // Make sure we're only initializing the module once
        if(_instance != null) return;
        _instance = this;
        Resource.SetGlobalKey(_instance, "MySocket");

        AddMember(new NativeFunction("connect", (NativeCallback)Connect));
        AddMember(new NativeFunction("send", (NativeCallback)Send));

    }

    // Send
    // Launched via Javascript
    string Send(Context c, object[] args)
    {
        var message = args[0] as string;
        try {
          socket.Send(Utf8.GetBytes(message));
        } catch(SocketException e) {
          Emit("onError", e.Message.ToString());
        }
        return "";
    }

And my .unoproj

{
  "RootNamespace":"",
  "Packages": [
  "Fuse.Maps",
  	"Fuse",
  	"FuseJS",
    "Fuse.Scripting"
  ],
  "Includes": [
    "*"
  ]
}

Hey!

Try adding "Uno.Net.Sockets" to your "Packages" array in the .unoproj. The reason it works in preview is likely that the package is pulled in by some other package.
