在我的项目中,每当我尝试将PivotItem添加到Pivot元素时,它都会错误地崩溃应用程序:

+       [System.Runtime.InteropServices.COMException]   {System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.
   at System.Runtime.InteropServices.WindowsRuntime.IVector`1.Append(T value)
   at System.Runtime.InteropServices.WindowsRuntime.VectorToCollectionAdapter.Add[T](T item)
   at testProj.MainPage.<OnNavigatedTo>d__3.MoveNext()} System.Runtime.InteropServices.COMException

当我在XAML中声明Pivot时会发生这种情况:

<Pivot>
        <PivotItem>

        </PivotItem>
    </Pivot>

当我尝试在代码隐藏中添加PivotItem以及完全在代码隐藏中创建Pivot时,会发生这种情况。 清洁和重建解决方案没有帮助。
