在花几分钟加载并给我这个异常后，设计器视图将起作用，但它太慢以至于几乎无法使用，并且会使我的整个 VS 会话滞后(当设计器视图关闭时它会自行更正).
After taking a few minutes to load and giving me this exception, the designer view will function but it is so slow that it is virtually unusable, and will make my whole VS session lag (It corrects itself when the designer view is closed).
我对 XAML 没有经验，所以我需要一种在创建时进行可视化的方法.有没有办法解决这个问题，或者我可以使用免费的扩展程序?
I'm not experienced in XAML, so I need a way to visualize as I create. Is there a way I can fix this, or a free extension that I can use instead?
推荐答案
已修复！这是通过卸载 .NET 4.6、安装 .NET 4、重新安装 Windows SDK，然后重新安装所有必要的 .NET 包来完成的.
Fixed! This was done by uninstalling .NET 4.6, installing .NET 4, reinstalling Windows SDK, and then reinstalling all the necessary .NET packages.
