Wpf在運行時為空白

我想用 2 個簡單的按鈕創建一個 WPF。在 IDE 中，它顯示了按鈕在運行時將如何顯示，除了運行時版本完全空白。我不知道如何解決這個問題，而且我已經厭倦了。這是我的 MainWindow.xaml ：

    <Window x:Class="WpfApp3.MainWindow"

MainWindow.xaml.cs ：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApp3
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

以及 Visual Studio 2022 中的預覽：

這里是在運行時打開的實際 WPF 視窗

uj5u.com熱心網友回復：

您已將事件附加到您的按鈕：

Click="btnFatInscription_Click"

但是這個事件在你后面的代碼中是不存在的。
