Visual Studio 2015社区 - XAML Desginer加载速度极慢

Question

我正在尝试创建一个WPF应用程序，但是当我打开XAML设计器视图时，我得到一个指向ActivityLog.xml文件的异常。错误条目显示在此处：

以下是异常细节：

在花了几分钟加载并给我这个例外后，设计器视图将起作用，但它太慢而几乎无法使用，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纠正）。

我没有XAML的经验，所以我需要一种在我创建时可视化的方法。有没有办法解决这个问题，或者我可以使用免费扩展程序？

Answer 1

固定！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需的.NET软件包来完成的。
