I recently ran into a problem with an Umbraco 13 web site where the culprit was that I had misplaced an item in the appsettings.json file. I did not get any warning anywhere - Umbraco kept going on with the default values and the IDE didn't really care either. 🙂 I might be showing my ignorance here, but is there any way to - preferably from within Rider - validate the appsettings file using the json schema or anything?
