ConfigureAppConfiguration not taken into account.

I tried to put kestrel urls into a separate json file so I don't have to recompile the project every time I change urls but the problem is that the ConfigureAppConfiguration doesn't work. I don't want to use the UseConfigurationMethod because I can't find a way to get the IHostingEnvironment to set up different settings for different environment. Putting these configurations in the Startup class doesn't seem to work either.

hosting.json

Doing it this way works:

dotnet run:

Now listening on: http://[::]:4000
Now listening on: http://[::]:5000
Now listening on: http://[::]:5001
Now listening on: http://[::]:5002
Now listening on: http://[::]:5003

But doing this will not:

dotnet run:

Now listening on: http://localhost:5000

If I do the first method, how do I get the Hosting Environment?
