Learning EF6 .NET Core, one-to-many and many-to-many relationships

What is the best way to learn .NET Core with EF 7?

For weeks now, I have been going through the tutorials on this site and each has limitations, so I seem to hit a brick wall when I try to add complexity with one-to-many, many-to-many relationships. Each is very good and I learn so much, but I am missing pieces. For example:

  • Rick Anderson, Getting started with ASP.NET Core MVC and VS does not include one-to-many, view models, many-to-many
  • Tom Dykstra, EF5 Code First Using MVC 5, does not include the .NET Core things, such as initializing with seed data and drop/create new DB in development, but the descriptions of view models are great, if only I could get it to work on .NET Core
  • ASP.NET Core Application to New Database does not include many-to-many

I watch videos, search Stack Overflow, watch Channel 9, try different approaches, and always hit a brick wall. Many times, I have a project working and then, mysteriously, the Program Manager Console commands that I have been using for so long, stop working with the dreaded add-migration command does not exist. I submit questions, research, try again and again. 

I guess what I am looking for is something like Tom Dykstra's course, but for .NET Core. Does that exist? 

Thanks for your ideas here.
