Questions under development of Desktop C#

Question

I’m starting to program in c# and I’m having some doubts. I would like to know where to start, for example:

I have a desktop system that I use in one company, I needed to develop another in the same pattern. There is for example this dialog box below and I don’t know how to create, because I can’t import the Windows.UI library here in my I can only make the message:

Messagebox.Show("");

I find this very ugly tbm.. kk How do I make you like that other model?

Answer 1

I started a project in Blend for Visual Studio 2013 generating the message by dialog. On the home screen I put an unnamed button with the inscription "Test":

After that, I selected the button and searched the properties of the button for the events I can put on the button. Double-clicking on "Click", Blend created the event for me as shown below:

Finally, my source was like this:

Mainpage.xaml.Cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
using Windows.UI.Popups; // Não esqueça de adicionar este using

namespace App1
{
    /// <summary>
    /// An empty page that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        }

        private async void Button_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
        {
            // Aqui crio uma mensagem de dialog e a exibo.
            MessageDialog dialog = new MessageDialog("Teste", "Teste Dialog");
            await dialog.ShowAsync();
        }
    }
}

The result was this:
