Use the "dotnet" binary and just run "dotnet restore"? This will restore whatever packages your project references-

Or are you thinking about pakage-management, as in searching for and installing new packages?

The latter. Installing works fine. Is there a way to not have to manually add packages?

most of the nuget operations (restore, pack, push) can be performed using dotnet.exe that ships as part of .NET Core Tools 1.0 on any platform. If you are facing any specific issue or need any nuget related help, please file an issue on https://github.com/nuget/home/issues and will do our best to respond asap!

Adding to rohit -> on linux you can try out dotnet binary available from https://github.com/dotnet/cli.
