框架使用.NET40；
Visual Studio 2019;
项目使用 MIT 开源许可协议；
项目使用 MVVM 模式来实现详细学习和理解 WPF；
新增功能：

通过托盘设置是否开机启动。
增加外部文件可拖放入到应用。

项目中技术使用到
WindowsAPI 、Style、CustomControl、Json 序列化和反序列化、换肤 Dark|Light、动画、Hook 按键与鼠标、颜色拾取、截图工具、DPI缩放、开机启动、NLog、转换器、禁止程序多开并唤醒之前程序等；
欢迎下载项目进行魔改；
更多效果可以通过GitHub^[1]|码云^[2]下载源码;
需注意程序不能以管理员身份运行，因为管理员身份运行Drop操作无效。

1）要允许控件Drop操作，首先必须设置控件属性AllowDrop="True"，这样控件才能产生DragOver/DragEnter/Drop等相关事件代码如下：

 <Canvas Background="Transparent" 
                x:Name="DragCanvas"
                AllowDrop="True" 
                DragOver="DragCanvas_DragOver"
                Drop="DragCanvas_Drop"
                Visibility="Collapsed">
            <StackPanel Orientation="Vertical" Name="DragStackPanel"
                        RenderTransformOrigin=".5,.5"
                        Opacity=".5">
                <StackPanel.RenderTransform>
                    <ScaleTransform x:Name="DragScaleTransform" ScaleX="1" ScaleY="1"/>
                </StackPanel.RenderTransform>
                <Image x:Name="DragImage" Stretch="Uniform"/>
                <TextBlock Name="DragTextBlock"
                    MaxWidth="70" 
                            TextWrapping="Wrap"
                            VerticalAlignment="Center"
                            Block.TextAlignment="Center" 
                            HorizontalAlignment="Center"
                            TextTrimming="CharacterEllipsis"
                            MaxHeight="40"
                            Foreground="{DynamicResource NormalWhiteBrush}"/>
            </StackPanel>
        </Canvas>

2）后台实现拖拽代码如下：

private void DragCanvas_DragOver(object sender, DragEventArgs e)
        {
            try
            {
                if (e.Data.GetDataPresent(DataFormats.FileDrop))
                {
                    var msg = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();
                    filePath = msg;
                    DragTextBlock.Text = System.IO.Path.GetFileName(filePath);
                    var icon = (BitmapSource)Common.GetIcon(filePath);
                    fileIcon = icon;
                    DragImage.Source = fileIcon;
                    var point = e.GetPosition(this);
                    var x = point.X - DragStackPanel.ActualWidth / 2;
                    var y = point.Y - DragStackPanel.ActualHeight / 2;
                    Canvas.SetLeft(DragStackPanel, x);
                    Canvas.SetTop(DragStackPanel, y);
                }
            }
            catch (Exception ex)
            {
                Log.Error("DragCanvas_DragOver:" + ex.Message);
            }
           
        }

        private void embedDeasktopView_DragEnter(object sender, DragEventArgs e)
        {
            AppSwitchListEmbedded.IsHitTestVisible = false;
            AppSwitchList.IsHitTestVisible = false;
            var doubleXAnimation = new DoubleAnimation
            {
                From = 0,
                To = 1,
                Duration = new Duration(TimeSpan.FromSeconds(0)),
            };
            DragScaleTransform.BeginAnimation(ScaleTransform.ScaleXProperty,doubleXAnimation);
            var doubleYAnimation = new DoubleAnimation
            {
                From = 0,
                To = 1,
                Duration = new Duration(TimeSpan.FromSeconds(0)),
            };
            DragScaleTransform.BeginAnimation(ScaleTransform.ScaleYProperty, doubleXAnimation);
            DragCanvas.Visibility = Visibility.Visible;
        }

        private void embedDeasktopView_DragLeave(object sender, DragEventArgs e)
        {
            DragInitial();
        }
        void DisposeDrag()
        {
            var storyboard = new Storyboard();
            var doubleXAnimation = new DoubleAnimation
            {
                From = 1,
                To = 0,
                Duration = new Duration(TimeSpan.FromSeconds(0.5)),
                EasingFunction = new BackEase { EasingMode = EasingMode.EaseIn },
            };
            Storyboard.SetTargetName(doubleXAnimation, "DragStackPanel");
            Storyboard.SetTargetProperty(doubleXAnimation, new PropertyPath("(StackPanel.RenderTransform).(ScaleTransform.ScaleX)"));
            var doubleYAnimation = new DoubleAnimation
            {
                From = 1,
                To = 0,
                Duration = new Duration(TimeSpan.FromSeconds(0.5)),
                EasingFunction = new BackEase { EasingMode = EasingMode.EaseIn },
            };
            Storyboard.SetTargetName(doubleYAnimation, "DragStackPanel");
            Storyboard.SetTargetProperty(doubleYAnimation, new PropertyPath("(StackPanel.RenderTransform).(ScaleTransform.ScaleY)"));
            storyboard.Children.Add(doubleXAnimation);
            storyboard.Children.Add(doubleYAnimation);
            storyboard.Completed += delegate 
            {
                DragInitial();
                var model = new ApplicationModel();
                model.ExePath = filePath;
                model.Name = DragTextBlock.Text;
                var iconPath = System.IO.Path.Combine(Common.TemporaryIconFile, model.Name);
                iconPath = iconPath + ".png";
                model.IconPath = iconPath;
                model.IsDrag = true;
                var firstModel = mainVM.ApplicationList.FirstOrDefault(x => x.Name == model.Name && x.ExePath == model.ExePath);
                if (firstModel != null) return;
                string first = model.Name.Substring(0, 1);
                if (!Common.IsChinese(first))
                {
                    if (char.IsUpper(first.ToCharArray()[0]))
                        model.Group = first;
                    model.Group = model.Name.Substring(0, 1).ToUpper();
                }
                else
                {
                    model.Group = Common.GetCharSpellCode(first);
                }
                mainVM.ApplicationList.Insert(0, model);
                if (File.Exists(iconPath))
                    return;
                Common.SaveImage(fileIcon, iconPath);
            };
            storyboard.Begin(DragStackPanel);
        }
