Run ASP.NET Core application in "Development" environment

I am using ASP.NET Core RC2 and when I run dotnet run my application always runs in "Production". I am not able to change it to "Development".

I have the following launchSettings.json file:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:26088/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "MVCCoreRc2App": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

I am not sure why dotnet is running the application in "Production" when I am setting "ASPNETCORE_ENVIRONMENT": "Development".

This was working in ASP.NET Core RC1. What am I missing?

You can even change the environment at the command line when you run your application as in:

dotnet run environment=development

If you're using Bash, the appropriate line is:

export ASPNETCORE_ENVIRONMENT=Development

You can set this in your ~/.bashrc file to make it apply whenever you log in.

launchsettings.json is used when launching from Visual Studio, but not from the command line dotnet.exe.

On the console set the environment variable before calling dotnet run.

set ASPNETCORE_ENVIRONMENT=Development
