APP 在 Windows.UI.Xaml.dll 中意外崩溃

Question

我的 UWP 应用程序在调试和发布时意外崩溃。它不依赖于移动鼠标或键盘上的按键。它可以工作几分钟或几小时，然后在 Windows.UI.Xaml.dll 中崩溃，有时在 SharedLibrary.dll 中。有趣的是，它在 64 OS Windows 上经常崩溃，但在 32 Windows 上却很少崩溃。 我在 Windows 10.0.17763 和 10.0.17134 中进行了测试。 在我的调试配置计算机上，它总是在 Windows.UI.Xaml.dll!ctl::ComObject::AddRef() 中崩溃 在 Outdoor.UWP.exe 中的 0x00007FF868934853 (Windows.UI.Xaml.dll) 处引发异常：0xC0000005：访问冲突读取位置 0x0000000000000008。 堆栈跟踪

请帮帮我。

我从 XAML 中删除了“{x:Null}”，在我所有 IValueConverter 的 ConvertBack 方法中将抛出 NotImplementedException 更改为 DependencyProperty.UnsetValue。但这并没有解决我的问题。

我创建了一些继承自 Control 和 Page 的用户控件。这些控件中的模板根是 Grid 和 Border。我向这些 xaml 元素添加了状态为“Normal”和“PointerOver”的视觉组“CommonStates”，并在 OnPointerEntered 和 OnPointerExited 事件处理程序中选择了这些状态。我必须添加这些状态，因为这些控件中没有默认状态，而且当鼠标悬停在我的用户控件上时，我不知道另一种更改界面的方法。 在显示这样的页面后，应用程序将能够在不同的地方使用此堆栈跟踪崩溃：通常是当用户在页面之间切换时。 解决方案：将组重命名为“MyCommonStates”并将状态重命名为“MyNormal”和“MyPointerOver”。之后，我的应用程序可以运行 2 或 3 周。 我的控件的 Xaml。

<Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="local:StatisticsValue">
                <Border x:Name="Part_Border">

                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="MyCommonStates">
                            <VisualState x:Name="MyNormal"/>
                            <VisualState x:Name="MyPointerOver">
                                <VisualState.Setters>
                                    ...
                                </VisualState.Setters>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>

                    ...
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>

<Grid x:Name="Root" Background="Transparent">

    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="MyCommonStates">
            <VisualState x:Name="MyNormal"/>
            <VisualState x:Name="MyPointerOver">
                <VisualState.Setters>
                    ...
                </VisualState.Setters>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>

    ...
    </Grid>

谁能解释一下为什么它解决了我的问题？
