Environment

Environment, for development is the deployment of a scenario, you can be debug scenes, test scenarios, production scenarios, of course, there can be many other scenarios, as long as your project needs can be customized, Microsoft helped us define three standard environment variables, the following.

Default definition of three scenarios

1. Development development Environment appsetting. Development.json
2. Staging test Environment appsetting. Staging.json

3. Production production environment appsetting. Production.json

   Note the point
4. If no environment variable is set, it defaults to Appsetting.json.
5. vs-> Project Properties-> Debug-> can add it, default is development, you can modify it as needed
6. You can add environment variables for the system, and the effect is the same

7. In Linux and Docker, you can also set Env to achieve the same effect
