How to load a wpf exe and start it by reflection entrypoint?

I want to load a wpf exe file and run it in a c# console program;

The wpf program is the default empty window of visual studio

The main program is a console program;

When I run the main program, I get a "Cannot locate resource 'mainwindow.xaml'" error.

What should I do.

mainApp

    public class Program
    {
        public static void Main(string[] args)
        {
            Assembly asm = Assembly.LoadFrom(@"WpfApp1.exe");

            try
            {

                MethodInfo method = asm.EntryPoint;
                method.Invoke(null, new object[] { });
            }
            catch (Exception extInfo)
            {
                Console.WriteLine(extInfo.ToString());
            }

            Console.WriteLine("DONE");
            Console.ReadKey();
        }
    }

App.xaml

<Application x:Class="WpfApp1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApp1"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
         
    </Application.Resources>
</Application>

MainWindow.xaml

<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:local="clr-namespace:WpfApp1"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        
    </Grid>
</Window>
