reading from appsettings in Program.cs using getsetting about hosting HOT 5 CLOSED

Can you show appsettings.json and the related environment variables?

Also, try making appsettings.json optional: false to make sure the file is being found correctly.

Hi, sorry let me explain better.
I did 2 scenarios:
A)
using just CreateDefaultBuilder without UseConfiguration
var hostBuilder = WebHost.CreateDefaultBuilder(args);

var settingName = "SHUTDOWNTIMEOUTSECONDS";
var settingStrShutdownTimeout = hostBuilder.GetSetting(settingName);

• launchSettings.json:
  SHUTDOWNTIMEOUTSECONDS not added to env vars
• appsettings.json:
  {
  "SHUTDOWNTIMEOUTSECONDS": 50
  }
  like this settingStrShutdownTimeout is null.
  Could it be that CreateDefaultBuilder only have the info from appsettings after
  IWebHostBuilder is Build()?

B) add UseConfiguration with the code above in the initial question.
files are with:

- launchSettings.json:
      "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Development",
    "ASPNETCORE_SHUTDOWNTIMEOUTSECONDS" : "50"
  }
- appsettings.json:
"SHUTDOWNTIMEOUTSECONDS": 30

I was expecting to get 50 because in LoadConfiguration we do AddEnvironmentVariables() after AddJsonFile("appsettings.json"...)

Thanks in advance.

AddEnvironmentVariables isn't working because you need to specify the prefix in order for the matching to work correctly: AddEnvironmentVariables("ASPNETCORE_").

hostBuilder.GetSettings reads only from the host config, where appsettings isn't loaded later until the app's config is build. That's why UseConfiguration works, it loads the config immediately into the host config.

Hi, understood.
