这个使用 .NET 的移动开发是否会影响 Windows UWP 开发?我目前并不真正需要 Android 开发工具.

Does this Mobile development with .NET impact in anyway Windows UWP development? I don't really need the Android development tools at this moment.

对此的最佳操作方案是什么 - 我尝试了两次安装，结果相同 - 我可以稍后自行安装组件吗?

What is the best course of action for this - I tried the install twice, with the same result - can I install the components later on their own?

编辑:Visual Studio 似乎运行正常，我可以打开我的 UWP 项目并运行它，所以到目前为止一切似乎都正常.这是安装的应用程序的版本

EDIT: Visual Studio seems to run correctly, and I can open my UWP project and run it so everything seems to work ok so far. This is the version of the application that was installed

Microsoft Visual Studio Community 2017
Version 15.0.26228.9 D15RTWSVC
Microsoft .NET Framework
Version 4.6.01586
Installed Version: Community

推荐答案

看看你的机器上是否有这个文件:

See if you have this file on your machine:

%programfiles(x86)%\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe

如果是这样，请使用 -full 参数从管理员命令提示符启动它:

If so, please launch it from an admin command prompt with a -full param:

InstallCleanup.exe -full

如果没有，请手动删除文件夹:

If not, please manually delete the folder:

%programfiles(x86)%\Microsoft Visual Studio\Installer

重新启动新下载的 vs_enterprise.exe(或 vs_professional.exe 或 vs_community.exe).允许第一步安装安装程序.

Relaunch the newly downloaded vs_enterprise.exe (or vs_professional.exe or vs_community.exe). Allow the first step to install the installer.

安装程序启动后，您可以看到工作负载选项(.NET 桌面等)，关闭它.去启动相同的 InstallCleanup.exe 来清理 VS 的旧版本.

Once the installer comes up and you can see workload choices (.NET desktop and the like), close it. Go launch the same InstallCleanup.exe to clean up old build of VS.

然后重新启动 vs_enterprise.exe 并安装

Then relaunch vs_enterprise.exe and install
