c# - Visual Studio 2015 XAML 设计器因 System.Exception 而失败

Question

我在 Windows 10 专业版正式版上运行 Visual Studio 2015 Community。 Visual Studio 安装没有任何问题或错误，但 XAML 设计器崩溃并出现以下错误:

System.Exception
Install failed. Please contact your software vendor.

我正在开发 Windows Phone 8.1 应用程序，但问题与我的应用程序无关，因为我尝试创建一个空白的 Windows 10 UWP 应用程序和一个空白的 Windows 8.1 通用应用程序，两者在尝试时都出现相同的错误为默认的 MainPage.xaml 打开 XAML 设计器。

我还尝试用它的另一个实例调试 Visual Studio，但它没有抛出任何异常。

这似乎是 XAML 设计器中的错误，但如果有人知道解决方法，请与我分享。

提前致谢!

编辑:

问题已由 Visual Studio 2015 Update 1 解决

Answer 1

对于许多其他人，在系统->高级系统设置->环境变量中删除“平台”环境变量已经解决了这个问题(主要是在 HP PC 或笔记本电脑上)。

您可能想试一试。有关详细信息，请参阅 XAML designer crash in VS 2015 on Windows 10
