I was using GitHub CoPilot and ran into a perfect example of keystrokes saved when writing boilerplate code. ​

First, I created a list here with jekyll and copied that list into a DbContext class that I wanted that seed data added to. As I was typing the first model data, copilot guessed what I wanted was from the pasted list so it was a bunch of TAB/ENTER and that boilerplate code was done without me having to fill in the blanks myself.

dotnet ef migrations add SeedCategoryData

and

dotnet ef database update

picked all of this up and created the seed data in the database. This is barely scratching the surface of how this thing could be useful. That's pretty cool.
