            我写了这个用户控件，它可能会有所帮助，它将显示带有进度条旋转的消息，以表明它当前正在加载内容。 
      <ctr:LoadingPanel x:Name=\"loadingPanel\"
                    IsLoading=\"{Binding PanelLoading}\"
                    Message=\"{Binding PanelMainMessage}\"
                    SubMessage=\"{Binding PanelSubMessage}\" 
                    ClosePanelCommand=\"{Binding PanelCloseCommand}\" />
    它具有几个可以绑定的基本属性。

            一个非常简单的“即插即用”微调器可以是Font Awesome Wpf软件包中的旋转图标之一（旋转图标）。 用法很简单，只需安装nuget软件包： 
    PM> Install-Package FontAwesome.WPF
    然后将引用添加到名称空间 
    xmlns:fa=\"http://schemas.fontawesome.io/icons/\"
    并使用ImageAwesome控件。设置Spin = \“ True \”属性，然后选择\“ Spinner \”，\“ Refresh \”，\“ Cog \”和\“ CircleOutlinedNotched \”图标之一。它具有可伸缩性，可以通过设置宽度和高度来调整大小。 
    <Window x:Class=\"Example.FontAwesome.WPF.Single\"
    xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"
    xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"
    xmlns:fa=\"http://schemas.fontawesome.io/icons/\"
    Title=\"Single\" Height=\"300\" Width=\"300\">
    <Grid  Margin=\"20\">
        <fa:ImageAwesome Icon=\"Refresh\" Spin=\"True\" Height=\"48\" Width=\"48\" />
    </Grid>
</Window>

            有图片 旋转图标选项的视觉摘要。使用Screen To Gif录制。 字体超赞WPF GitHub上的文档。 通过NuGet安装：   PM>安装包FontAwesome.WPF 看起来像这样： XAML： 
    <fa:ImageAwesome Icon=\"Spinner\" Spin=\"True\" SpinDuration=\"4\" />
    图中的图标为
    Spinner
    ，
    CircleOutlineNotch
    ，
    Refresh
    和
    Cog
    。还有很多。 @HAdes中的方法 XAML复制/粘贴。

            在WPF中，您现在可以简单地执行以下操作： 
    Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; // set the cursor to loading spinner

Mouse.OverrideCursor = System.Windows.Input.Cursors.Arrow; // set the cursor back to arrow

            这是对@HAdes给出的用于参数化宽度，高度和椭圆尺寸的代码的更新。 此实现可自动计算飞行中所需的角度，宽度和高度。 用户控件绑定到自身（在代码后面），它负责所有计算。 XAML

            您可以仅使用“图像”控件和变换来执行此操作，而无需任何其他控件和库： 
    <Image
    Source=\"/images/spinner.png\"
    Width=\"100\"
    Height=\"100\"
    RenderTransformOrigin=\"0.5, 0.5\" Visibility=\"{Binding IsLoading, Converter={StaticResource BooleanToVisibilityConverter}}\">
    <Image.RenderTransform>
        <RotateTransform x:Name=\"noFreeze\" />
    </Image.RenderTransform>
    <Image.Triggers>
        <EventTrigger RoutedEvent=\"Loaded\">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation
                        Storyboard.TargetProperty=\"(Image.RenderTransform).(RotateTransform.Angle)\"
                        To=\"360\" Duration=\"0:0:1\" RepeatBehavior=\"Forever\" />
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Image.Triggers>
</Image>
    用图像替换
    /images/spinner.png
    。如果要逆时针旋转将
    To=\"360\"
    更改为
    To=\"-360\"
    。 
    Duration=\"0:0:1\"
    等于每旋转1秒。

    荒劫娇噬

            使用枚举类型指示您的ViewModel的状态 
    public enum ViewModeType
{
    Default, 
    Busy
    //etc.
}
    然后在您的ViewModels Base类中使用一个属性 
    public ViewModeType ViewMode
{
    get { return this.viewMode; }
    set
    {
        if (this.viewMode != value)
        {
            this.viewMode = value;
                            //You should notify property changed here
        }
    }
}
    在视图中触发ViewMode，如果它很忙，请显示busyindicator： 
    <Trigger Property=\"ViewMode\" Value=\"Busy\">
    <!-- Show BusyIndicator -->
</Trigger>

            github上的这个仓库似乎做得很好： https://github.com/blackspikeltd/Xaml-Spinners-WPF 旋转器重量轻，可以轻松放置在需要的地方。存储库中包含一个示例项目，该示例项目显示了如何使用它们。 也没有令人讨厌的代码，也没有一堆逻辑。如果需要MVVM支持，则只需将其放入具有可见性绑定的Grid中即可。

            @Menol发布的自定义微调器有一个小问题，即微调器将向右下移动一个点的大小。我已经更新了代码，以便通过将点减去一半来补偿此偏移量。 这是更新的代码： 
        private void initialSetup()
    {
        float horizontalCenter = (float)(SpinnerWidth / 2);
        float verticalCenter = (float)(SpinnerHeight / 2);
        float distance = (float)Math.Min(SpinnerHeight, SpinnerWidth) / 2;
        float dotComp = (float)(EllipseSize / 2);

        double angleInRadians = 44.8;
        float cosine = (float)Math.Cos(angleInRadians);
        float sine = (float)Math.Sin(angleInRadians);

        EllipseN = newPos(left: horizontalCenter - dotComp, top: verticalCenter - distance - dotComp);
        EllipseNE = newPos(left: horizontalCenter + (distance * cosine) - dotComp, top: verticalCenter - (distance * sine) - dotComp);
        EllipseE = newPos(left: horizontalCenter + distance - dotComp, top: verticalCenter - dotComp);
        EllipseSE = newPos(left: horizontalCenter + (distance * cosine) - dotComp, top: verticalCenter + (distance * sine) - dotComp);
        EllipseS = newPos(left: horizontalCenter - dotComp, top: verticalCenter + distance - dotComp);
