.NET Core - Set Environment Variable in Azure Deployment Task

Question

I'm currently trying to use the launchSettings.json file to manage the environment variables of the application, so my Setup.cs file can manage the environments in the way of env.IsDevelopmentEnvironment(), etc.

In VSTS, how do I go about setting the environment variable ASPNETCORE_ENVIRONMENT on an Azure Deployment task? Or should it get in the dotnet publish task I've got in my build steps?

Answer 1

o define your own environment variable, click to your site → All Settings → Application settings:

Add an app setting in the "App settings" section:

You can verify the value from the debug console.
