Appsettings.json Different Versions?

Question

I am starting asp.net core 2.1 coming from .NET and wondering how do I make multiple AppSetting.json files?

Before we had the webconfig that you could have webconfig.deb

By default ASP.NET Core will attempt to load an additional appsettings.<EnvironmentName>.json file. Using the default environment names available, this allows you to create the following files:

• appsettings.json - loaded regardless of the environment name
• appsettings.Development.json - loaded only when the environment name is Development
• appsettings.Staging.json - loaded only when the environment name is Staging
• appsettings.Production.json - loaded only when the environment name is Production

The name of the environment is usually controlled via the ASPNETCORE_ENVIRONMENT environment variable or via launchSettings.json when developing (checkout the docs).

Take a look at the documentation for configuration for more info regarding this topic.
