Application cannot find static Main Method after installing

[AndreasReitberger]

Hi, I installed your package via NuGet. Now my application cannot be started any more. That's the issue from VS2017: CS5001 The program has now static method which can be used as entry point (translated from German).

I tried two projects, same problem. I made the adjustments to the app.xml / app.xml.cs file

app.xml.cs

using WPFSharp.Globalizer;

namespace UI
{
    /// <summary>
    /// Interaktionslogik für "App.xaml"
    /// </summary>
    public partial class App : GlobalizedApplication
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            // get the current app style (theme and accent) from the application
            // you can then use the current theme and custom accent instead set a new theme
            Tuple<AppTheme, Accent> appStyle = ThemeManager.DetectAppStyle(Application.Current);
            Configuration MyConfiguration = Configuration.Instance;
            Design design = Design.Instance;
            // now set the Green accent and dark theme
            if (design.THEME_NAME != null && design.THEME_APP_STYLE != null)
            {
                var t = design.THEME_NAME;
                var z = design.THEME_APP_STYLE;
                ThemeManager.ChangeAppStyle(Application.Current,
                                            (design.THEME_NAME),
                                            (design.THEME_APP_STYLE)); // or appStyle.Item1
            }
            System.Threading.Thread.CurrentThread.CurrentUICulture = design.GENERAL_LANGUAGE;
            base.OnStartup(e);
        }

        public App()
        {
            //System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US");
            //System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en"); 
        }
    }
}

app.xml

Did I miss anything?

Thanks for helping!

Fixed it by my own. The "Build type" of the App.xaml file needs to be set to "ApplicationDefinition". Then it works. Sorry for bothering you.
