The code sample you have shown uses NuGet 2 which is not supported on .NET Core. You'll need to use NuGet 3 or the (soon to be released) NuGet 4. These APIs are a huge break from NuGet 2. One of these breaking changes is that NuGet.Core is obsolete on won't be ported to .NET Core.

Checkout NuGet API v3 on docs.microsoft.com for info on NuGet 3. At the time of writing, this doc is basically a big TODO and doesn't have much info.

Here are some blog posts that are more useful.

And of course, you can always go spelunking through NuGet's source code to find more examples. Most of the core logic lives in https://github.com/nuget/nuget.client.
