Is launchSettings.json used when running ASP.NET 5 apps from the command line on Mac?

Question

I am developing an ASP.NET 5 Web API app using Visual Studio code on Mac. I manually modified my Properties/launchSettings.json file to set environment to Sta

Answer 1

LaunchSettings.json is strictly a VS concept. In other cases, you will have to configure environment variables as commands below:

For standard command line run, use:

set ASPNET_ENV=Development

dnx web

For powershell, use:

$env:ASPNET_ENV='Development'

dnx web

Shorter version: dnx web ASPNET_ENV=Development

Answer 2

Adding to @Chrysalis answer, you could also avoid "messing" with current environment by passing needed variables on command line.

Inside project.json file, say that you have a web-dev command specific for development environment:

"commands": {
  "web-dev": "Microsoft.AspNet.Server.Kestrel 
    --ASPNET_ENV Development --Hosting:Environment Development 
    --config hosting.Development.json",
},

where you can see how both ASPNET_ENV, Hosting:Environment are set, as well as invoking a specific hosting.json configuration.
NOTE: command is split on several lines just for readability, join again before actually pasting in JSON file.
