下面说说解决方案

下载包 

https://vsdebugger.azureedge.net/vsdbg-(你的版本号.号换成-号)/vsdbg-(你的Runtime ID).zip

例如我的

https://vsdebugger.azureedge.net/vsdbg-16-0-20412-1/vsdbg-linux-x64.zip
下载之后解压到你的安装路径
例如我的

-InstallPath "C:UsersMESTCvsdbgvs2017u5"
 然后在该文件下添加一个success_rid.txt文件,内容为你的Runtime ID
例如我的linux-x64
还要添加一个success_version.txt文件,内容为你的版本号,如16.0.20412.1

重启 visual studio 
下面还会下载另一个,相同的处理方式,再重启一次就ok了

解压路径

C:Users用户名vsdbgvs2017u5 ->  vsdbg-linux-x64.zip

C:Users用户名vsdbgvs2017u5linux-musl-x64 ->  vsdbg-linux-musl-x64.zip

解压完了,在路径 C:Users用户名vsdbgvs2017u5 里面 新建 success_rid.txt 编辑内容 linux-x64,再新建 success_version.txt 编辑内容 16.2.10709.2

在路径 C:Users用户名vsdbgvs2017u5linux-musl-x64 里面 新建 success_rid.txt 编辑内容 linux-musl-x64,再新建 success_version.txt 编辑内容 16.2.10709.2
