WPF性能 - 查找布局传递调用的来源

Question

有没有办法找出控件的WPF布局传递的原因/内容？

我目前正在跟踪为主要用户控件调用的Arrange Overrides的数量：

public partial class MyView
{
    private ulong _arrangeCount;
    protected override Size ArrangeOverride(Size arrangeBounds)
    {
        Debug.WriteLine($"TTV - ArrangeOverride - {_arrangeCount++}");
        return base.ArrangeOverride(arrangeBounds);
    }
}

加载视图的计数是40！使用复杂的UI（数据网格嵌套，100个单元格和列，单元格，行的自定义模板）这需要几秒钟！ （很大一部分时间花在测量/安排上）

有没有办法找出每次传球的来源？

目前我正在从用户控件中删除内容，并试图找出造成这些内容的原因。

我注意到有很多东西存储在有效值中，可能是因为主控制资源字典中的样式/模板中存在绑定？

是否会更新这些有效值（即使其中一些不影响此父控件，会导致调整/安排被调用？）

我已设法将测量大小缓存如下，这似乎在测量方面有所帮助，但是对于排列，我不能做同样的事情，因为在内容绑定后它没有正确排列！

    private Size _lastMeasureConstraint;

    private ulong _measureCount;
    protected override Size MeasureOverride(Size constraint)
    {
        if (_lastMeasureConstraint == constraint)
            return constraint;

        Debug.WriteLine($"TTV - MeasureOverride - {_measureCount++}");
        _lastMeasureConstraint = constraint;
        return base.MeasureOverride(constraint);
    }

大部分措施/安排覆盖的堆栈：
