I created a short, 30 minutes video on how to get started with Entity Framework 7 Migrations inside ASP.NET v. next (ASP.NET 5). I decided that video would be much better than huge blog post with a ton of screenshots. II uploaded it to YouTube to my channel as a means to share my experiment. There will be more short videos to come, or so I hope. You can see the video here.
Please let me know what you think about it. You can download source code here.
