c# - 「無効なウィンドウハンドル」win32 例外

Question

C#アプリケーションで以下の例外が発生する原因を知っている人はいますか?

これを行うことで、マシンで一貫して再現しています：

特定のダイアログ (WPF ウィンドウ) を開きます
いくつか選択してウィンドウを閉じます
閉じてから数秒後、以下のスタックトレースで例外が発生します

私のマシンでのみ発生するようで、他のマシンでは再現できませんでした。

編集: ClientToScreen メソッドはユーザーコードから直接呼び出されていないようです。関連する他のスレッドが見つからなかったため、クラッシュは以前の操作の副作用であると想定しています。

EDIT2:コードでバイナリ検索を行う(コメントする)ことで、ビューモデルのOnClosingハンドラーで呼び出されている以下のCleanupメソッドが原因であることがわかりました-そのメソッドは、とりわけDisposeを呼び出していますWindows フォームの WPF ラッパーのように機能するオブジェクト。コメントすると、クラッシュはもう発生しません。

protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
{
   base.OnClosing(e);
   m_pickerViewModel.Cleanup();
}

public bool CloseView() 
{
    this.Dispose(true);
    return true; 
}
