That is really good explanation even asp net core mvc and console too! Thank You! I did in .Net6 Asp Net Core MVC, it's just slightly different:
in the program.cs :

and in the controller I passed all with ViewBag like this:
ViewBag.Var1 = _options.Value.Name;
ViewBag.Var2 = _options.Value.Address;
ViewBag.Var3 = _options.Value.Age;

Hi David, that was a very nice video.

How would you seamlessly encrypt/decrypt values of your custom configuration section in appsettings.json file?

An object reference is required for the nonstatic field, method, or property 'member'

In the Program.cs (Startup in .net 6)
