我对此感到有些沮丧,也许有人遇到了类似的问题或者想知道如何修复它.

我升级到Windows 10.
我安装了Visual Studio 2015社区.
我创建了一个新的解决方案,只有一个项目用于空白的通用Windows应用程序.我正在使用C#.

问题: 我试图在设计器中打开MainPage.xaml,但设计器不会加载.我NullReferenceException在设计师窗口中得到了一个.我尝试在Blend中打开它,结果相同.正如Visual Studio建议的那样,我尝试关闭"选项"菜单中的"在XAML Designer中运行项目代码"功能,但它没有帮助.

在设计器中打开其他xaml文件没有问题(WPF,Windows Phone 8或8.1 Universal应用程序都可以正常工作).该应用程序在本地计算机上运行,​​在模拟器中,只有设计师才能执行.

欢迎任何建议.
