Answer 1

So I want to write the connection string straight into OnConfiguring method:

How can I extract connection string from appsettings.json into ApplicationContext class?

I wouldn't like to create any constructors for ApplicationContext class.

You could use Options Pattern via IOptions but the easiest way is using DI in ApplicationContext constructor ;)

Follow below articles, please:

• Example of using IOptions,
