To clarify, I mean writing scripts that generate or modify classes for you instead of manually writing them every time, for example if you want to replace reflection with a ton of verbose repetitive code for performance reasons I guess?
My only experience with this is just plain old manual txt generation with something like python, and maintaining legacy t4/tt VS files but those are kind of a nightmare.
What’s a good modern way of accomplishing this, have there been any improvements in this area?
Is it prohibitively expensive to manually define your data types? How many do you have?
I do not generally recommend using ORMs, but this advice is likely dependent on the particular ecosystem you are dealing with.
It seems like you are pretty deep into Microsoft/.NET territory. I don’t have any experience with .NET so I might not be the best person to help.
