I placed a bunch of items in the "appsettings.json" file in my project. Both at startup in Program.cs, and on any Razor component page where I inject IConfiguration, they all come back with null whenever I try to read any of the values I added to that file. Any default values it will access, but any custom values (new or changed) it will not.
Why isn't IConfiguration reading from the appsettings or appsettings.Development files?
