Visual Studio Designer不显示UWP应用程序的控件 [英] Visual Studio Designer not showing controls for UWP Apps

问题描述

XAML设计器没有以可见的方式显示控件。如果单击了应该显示轮廓边框的位置，并选择了正确的xaml代码，则控件就在那里。没有选择任何内容，它看起来像是一个空白的托盘，仅勾勒出页面轮廓。我尝试了蓝色，蓝色额外对比度，深色和浅色主题。同一期发行所有主题。我也尝试过在ARM，x86和x64之间切换，而这三个问题都存在。错误列表中没有消息。打开多个解决方案的结果相同。

XAML Designer is not displaying controls in a way they are visble. The controls are there, if you click where one should be the outline borders are highlighted and the proper xaml code is selected. With nothing selected it looks like a blank pallet with just the page outlined. I have tried the blue, blue extra contrast, dark and light color theme. Same issue all themes. I have also tried switching between ARM, x86 and x64 with issue in all three. There are no messages in the Error List. Have opened multiple solutions same result.

进一步在Visual Studio Designer中面临的问题与您的CPU性能有关，可以保护设计人员实时更新，您可以尝试调试您的应用，这可能会给出正确的结果。
并在任务管理器中查找除Visual Studio及其组件以外的任何进程都可能消耗您的CPU和RAM-

And find processes in task manager any process other than visual studio and its components may consume your CPU and RAM-

并查看您的系统配置，这应该足够了，但是您不需要非常高配置的PC来进行应用开发，它应该最小化，可以轻松处理所有可视工作室流程，如果您打算进行游戏开发，则根据您的游戏开发需要更高的游戏水平。

And View Your System Configuration which should be enough but you don't need very high configuration PC for app development it should minimal which can easily handle all visual studio process , if you planning to game development then you need a higher one according to your game development.
