Sounds like you might have some libraries that aren't Core compatible. If Nuget is expecting/requiring 4.7.2, then something is likely still targeting it, either in your project or a library I'd venture. Would also explain why cleaning up the Nuget packages and restoring them doesn't fix the issue if the package that you're restoring still targets 4.7.2.

Related note, are you sure that you're using the latest project structure? I noticed that your error message includes project.json, which was deprecated in favor of the new csproj format; more info is here if it's relevant. I'm not aware of a situation where you'd get an error message about project.json and the solution didn't have a project.json.
