I have a .net core web api project that references 4.x assemblies that have app.config settings. Can I convert the app.config settings to appsettings.json without modifying the old assemblies or do I just drop in an app.config file with the settings for the older assemblies? If I just drop in app.config files, how can I change those settings on publish?
So what I ended up doing is just adding app.config files. I also added an app.release.config and rename it to app.config as part of my publish process. I could not use config transformations. I could not get that to work in Azure CI at all.
