possible (its a file in the root of the site, you can read/save it) but not recommended! the settings might not actually be in the

appsettings.json

file, .net combines all the versious appsettings.*.json files (e.g

appsettings.development.json

) and Envrionmental Variables and even possibly Azure Key vault . so you see the Configuration as a single thing but actually its munged from all over the place.
