Question

我正在尝试在Visual Studio 2017版本15.8.4中打开Xamarin项目，但是它没有打开，显示（需要迁移）。

当我尝试重新加载时，会弹出此窗口。

当我单击“确定”按钮时，它会将我重定向到此页面。

当我单击链接时，它会将我重定向到此页面。

https://docs.microsoft.com/en-us/visualstudio/porting/porting-migrating-and-upgrading-visual-studio-projects?view=vs-2015。

我已通过上面的链接，但无法解决问题。

我能够在Visual Studio 2015中打开该项目。

Visual Studio 2017“关于”窗口。

Answer 1

我有这个问题的原因。

我有一个基于VS 2015构建的Xamarin Windows 8.1应用程序项目。但是我试图在VS 2017中打开它。而且VS 2017不支持Windows 8.1应用程序，它支持UWP应用程序。

所以您有两个选择。

如果您需要将Windows 8.1应用程序手动转换为UWP应用程序只想在VS 2017中工作。
只需对VS 2015感到满意，然后开发Windows 8.1应用即可。

无法在Visual Studio 2017中打开项目
