How to use publish profile to target different environment

Question

I would like to publish my app using all those 3 different predefined environment variables(Development, Staging, and Production), but I cannot figure out how to target different environment when creating the publish profile.

Since .NET Core doesn't support multi-version of web.config, I cannot use environmentVariable tag in config file to automate my publish.

I also tried launchSettings.json, everything seems fine in VS and I can run different environment locally. I just want to automate my publish process too, so when I use different publish profile and then different environment is targeted.

Publish profile is used by dotnet publish command, that only packs app+dependencies and makes them ready for deployment:

dotnet publish compiles the application, reads through its dependencies specified in the project.json file and publishes the resulting set of files to a directory.

You specify Environment on target platform, where you do deployment, by using ASPNETCORE_ENVIRONMENT environment variable.
