Question

我的UWP应用程序意外地在调试和发布时崩溃。它不依赖于移动鼠标或按下键盘上的键。在Windows.UI.Xaml.dll中，有时甚至在SharedLibrary.dll中，它可能会工作几分钟或几小时，然后崩溃。有趣的是，它在64 OS Windows上经常崩溃，但在32 Windows上很少崩溃。我在Windows 10.0.17763和10.0.17134中进行了测试。在调试配置下的计算机上，它总是在Windows.UI.Xaml.dll！ctl :: ComObject :: AddRef（）中崩溃，并且在Outdoor.UWP.exe中的0x00007FF868934853（Windows.UI.Xaml.dll）处引发的异常：0xC0000005：访问冲突读取位置0x0000000000000008。堆栈跟踪

请帮助我。

我从XAML中删除了“ {x：Null}”，并在所有IValueConverter的ConvertBack方法中将NotImplementedException的抛出NotImplementedException更改为DependencyProperty.UnsetValue。但这并不能解决我的问题。

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元素添加了具有状态“ Normal”和“ PointerOver”的可视组“ 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，并且当用户将鼠标悬停在用户控件上时，我不知道另一种更改界面的方法。显示此类页面后，应用程序将能够在不同位置使用此堆栈跟踪崩溃：在用户在页面之间切换时，这种情况非常常见。解决方案：将组重命名为“ MyCommonStates”，并将状态重命名为“ MyNormal”和“ MyPointerOver”。之后，我的应用程序可以工作2到3周。 Xaml我的控件。

<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>

有人可以向我解释为什么它可以解决我的问题吗？
