Er, a lot? If your codebase is well structured most of it will follow similar patterns which you just need to repeat, with different class/variable names etc. That makes it ripe for automation with Copilot.

Then there's unit tests which cover the above - if you keep the structure similar then copilot can fly through it.

Likewise for generating things like seed data. Need to create some seeds for your database just write out what you need in a comment and Copilot gets it mostly right.

So much time saved.
