我刚刚完成了Windows 10 Build 16232的全新安装,并使用 UWP、.NET 和 Xamarin“默认”包安装了Visual Studio Community 2017 Preview 。我创建了一个空白的 UWP 应用程序,放置了一个文本框,然后……出错了。
这是 XAML:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<TextBox Text="Hello World!"/>
</Grid>
现在,对于错误:
Exception: Unable to create an instance of "TextBox".

这是我尝试过的:
- 调试 x86
- 调试 ARM
- 调试 x64
- 以管理员身份运行
chkdsk
- 重新安装 Visual Studio
- 重新安装 Windows 10 Build 16232 (慢环)
- 安装 Visual Studio 社区 2017
- 卸载 Xamarin
- 升级到 Windows 10 Build 16241 (快速环)
其他所有常见控件都可以工作,但不是那个。我如何使它工作?问题只出在设计师身上;我可以很好地编译应用程序。
