【问题讨论】：

它抛出了什么异常？
COM 引用，所以我的 xaml 中的某些内容是错误的
{System.Exception: 对 COM 组件的调用已返回错误 HRESULT E_FAIL。在 MS.Internal.XcpImports.CheckHResult(UInt32 hr) 在 MS.Internal.XcpImports.UIElement_Measure(UIElement element, Size availableSize) 在 System.Windows.UIElement.Measure(Size availableSize) 在 System.Windows.Controls.ScrollContentPresenter.MeasureOverride(尺寸约束）在 System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Double inWidth, Double inHeight, Double& outWidth, Double& outHeight)}
出现上述错误是因为 Visual Studio 的缓存损坏。为了解决这个问题，只需尝试删除项目缓存。
C:\Program Files\Microsoft Visual Studio X\Common7\IDE\ProjectTemplatesCache C:\Program Files(x86)\Microsoft Visual Studio X\Common7\IDE\ProjectTemplatesCache

【解决方案1】：

Nvm 我刚刚找到了一个解决方案，通过在代码隐藏中设置颜色可以正常工作，而不必为样式模板等而苦恼

 private void autobxCountry_GotFocus(object sender, RoutedEventArgs e)
    {
        autobxCountry.Background = new SolidColorBrush(Colors.White);
        autobxCountry.Foreground = new SolidColorBrush(Colors.Black);
    }
