更新dotnet cli和aspnetcore以澄清问题，因为这封电子邮件是对我4天来从不同来源混合和匹配软件包的经验的详细描述 问题开始于运行时，没有编写一行代码，只是在visual studio 2017 15.3中f5了默认的mvc模板

它们是预发布库。你期待什么？当我观看时，那是一个坏主意。这是一个专门针对Signar core新用户的视频，告诉他们安装夜间软件包。只是自找麻烦。我能够让预览版正常工作。在发现javascript npm软件包之前，我和你一样有很多错误已重命名。此外，您的ASP.NET核心版本和javascr

doesnt seem to have a client for me.
i tried npm install signalr-client --registry https://dotnet.myget.org/F/aspnetcore-release/api/v3/index.json --save-dev
but that doesnt work so i went with the original one from the video
npm install signalr-client --registry dotnet.myget.org/F/aspnetcore-ci-dev/npm --save-dev
i also tried the one from aspnet core github site https://github.com/aspnet/SignalR

thanks that works but now docker image deployment breaks :(
are there any docs out there that can guide me to create my own aspnetcore 2.1 linux docker image to deploy to?
