Setting SizeToContent fom Child UserControl cause FatalExecutionEngineError

我已經添加了一個依賴項屬性到我的視圖基類，它應該允許子UserControls設置父窗口上的一些屬性，一個是SizeToContent。當我OnSizeToContent方法運行，當其試圖改變從WidthAndHeight主窗口的SizeToContent爲手動，我得到這個奇怪的錯誤：檢測Setting SizeToContent fom Child UserControl cause FatalExecutionEngineError

FatalExecutionEngineError 消息：運行時遇到一個致命錯誤。錯誤的地址是0x58e29ddd，線程0x17e8。錯誤代碼是0x80131623。此錯誤可能是CLR中的錯誤，也可能是用戶代碼中不安全或不可驗證的部分。此錯誤的常見來源包括COM-interop或PInvoke的用戶編組錯誤，這可能會破壞堆棧。

從來沒有見過這個錯誤，我不知道如何調試這個，搜索沒有發現任何相關的。

任何人都可以破譯？

private static void OnSizeToContentChanged(DependencyObject o, DependencyPropertyChangedEventArgs e) 
{ 
    if (Designer.IsInDesignMode) 
      return; 
    ((ViewBase) o).MainWindow.SizeToContent = (SizeToContent) e.NewValue; 
} 

private static readonly DependencyProperty SizeToContentProperty = 
    DependencyProperty.Register("SizeToContent", typeof(SizeToContent), typeof(ViewBase), 
      new UIPropertyMetadata(SizeToContent. WidthAndHeight, OnSizeToContentChanged));

這裏的局部堆棧跟蹤OnSizeToContentChanged後：

編輯＃1：

我看着我的窗口權當SizeToContent設置的屬性。 IsMeasureValid = false，並且IsArrangeValid =真，然而從MSDN：

如果IsMeasureValid爲假，IsArrangeValid也必須是假的（由佈局處理的執行邏輯，配置不能沒有測量第一個是有效的有效期）。

我有一個ResizeMode類似的屬性，當這個改變時，似乎設置了IsMeasureValid = false。

我應該注意，我做了這個，所以我可以在我的XAML中添加ResizeMode =「CanResizeWithGrip」SizeToContent =「Manual」。

我做了一些嘗試InvalidateArrange和UpdateLayout，但沒有骰子。我可以生活在沒有它，但我真的想弄清楚......

Brr中，你不得不懷疑，如果這是真的意味着是生產代碼。故意調用FailFast有點粗俗。 – 2010-10-15 16:26:43

看着System.Windows.UIElement.PropagateResumeLayout，斷言失敗，如果一個措施或安排通過已經進行時該方法被調用。

有沒有可能是你的用戶控件試圖設置SizeToContent屬性，當它被調整或在WPF問它任何其他國家進行佈局或安排通？
