Hide console app but still show tray Icon

Hey, i'm making a tray icon only app, the tray icon works fine,but not when I set the output to Windows Application to hide the console.

using System.Runtime.InteropServices;

❔ Find last element in dictionnary, using a list as path

Hey, I have a dictionnary:

c# 
Dictionary<string, object> tree => new()
    {
        { "show", new Dictionary<string, object>() { { "10", null } } },
        { "clear", null },
        { "true", null },
        { "false", null}
    };

c# 
Dictionary<string, object> tree => new()
    {
        { "show", new Dictionary<string, object>() { { "10", null } } },
        { "clear", null },
        { "true", null },
        { "false", null}
    };

like this, and i wanna make a function that return me the next/end word. Like if I input 'sh' i wanna have 'ow', and if I input 'show' I wanna have 10, but if i input 'show 10' then only return a null value.

❔ Interactive both in y and x axis, in cmd

Hello :), I am trying to do an interactive menu in a command line application that use both the x and y axis, you navigate using keyboard arrows. I did a well working one that is only using the x axis, but with both this is way more complicated. I wrote a code that kind of works but for any reason the Console.Clear is not doing what i was expecting :

public static void Editing()
    {
        int x = 0;
        int y = 0;
        List<Option> x_options = new List<Option>();
        List<string> y_options = GetPrompt();
        List<string> special = new List<string>() { "%path", "%user", "%os", "%workingset", "%time", "%date", "%newline" };
        List<string> colors = new List<string>() { "%fore:", "%back:", "%style:" };
        while (true)
        {
            if (special.Contains(y_options[y]) || colors.Contains(y_options[y]))
            {
                x_options.Add(new Option(CustomCMD.GetValue("tips"), () => { }));
            }
            x_options.Add(new Option(CustomCMD.GetValue("edit"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("add_right"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("add_left"), () => { }));
            x_options.Add(new Option(CustomCMD.GetValue("delete"), () => { }));

            WriteComplexMenu(x_options, y_options, x_options[x], y_options[y]);
            ConsoleKeyInfo key = Console.ReadKey();
            if (key.Key == ConsoleKey.RightArrow)
            {

    }

Editing is the main code that run the menu and handle the user input
