Windows Phone 8 application won't start unless in debug mode

it helps some times again for all the help with this. It turns out I'd just made a mistake and not noticed that a library I was using was statically linked against a different version of the MSVC runtime. That was causing on end of problems.

Any of those help A Visual Studio project keeps application settings organized in three PropertyGroups. Debug, Release, and a set of options that are independent of the active configuration. OutputType is in that last one.
The workaround is to simply create the console yourself. Use the Application.Startup event, like this:

public partial class App : Application {
    private void Application_Startup(object sender, StartupEventArgs e) {
#if DEBUG
        AllocConsole();
        Console.WriteLine("Hello world");
#endif
    }

    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    private static extern bool AllocConsole();
}

fixed the issue. Will look into that further Well, I found out what was the problem.
My Show/Hide functions look like these now:

public void Hide()
    {

        UnityApp.Obscure(false);
        UnityApp.Deactivate();
        MainPage.Instance.Dispatcher.BeginInvoke(() =>
        {
            MainPage.Instance.DrawingSurfaceBackground.SetBackgroundContentProvider(null);
            MainPage.Instance.DrawingSurfaceBackground.SetBackgroundManipulationHandler(null);
            MainPage.Instance.HideUnityBorder.Visibility = Visibility.Visible;
            MainPage.Instance.ApplicationBar.IsVisible = true;
        });
    }

    public void Show()
    {
        var content = Application.Current.Host.Content;
        var width = (int)Math.Floor(content.ActualWidth * content.ScaleFactor / 100.0 + 0.5);
        var height = (int)Math.Floor(content.ActualHeight * content.ScaleFactor / 100.0 + 0.5);
        UnityApp.SetNativeResolution(width, height);
        UnityApp.UnObscure();
        MainPage.Instance.Dispatcher.BeginInvoke(() =>
        {
            MainPage.Instance.DrawingSurfaceBackground.SetBackgroundContentProvider(UnityApp.GetBackgroundContentProvider());
            MainPage.Instance.DrawingSurfaceBackground.SetBackgroundManipulationHandler(UnityApp.GetManipulationHandler());
            MainPage.Instance.HideUnityBorder.Visibility = Visibility.Collapsed;
            MainPage.Instance.ApplicationBar.IsVisible = false;
        });
    }

this will help After talking to the team at PubNub there is a fix on the development branch that should be available on the master branch soon via their C# github repo (https://github.com/pubnub/c-sharp/tree/master/windows-phone-8).

wish help you to fix your issue The problem is that app.js is exporting an app object, not starting a server. If you look at the code for bin/www you'll see that it loads the app object and uses it to start a server.

#!/usr/bin/env node
var debug = require('debug')('tmp');
var app = require('../app');

app.set('port', process.env.PORT || 3000);

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});
