How to Use
The following example shows how to read application configuration from environment variables.
using System;
using Microsoft.Extensions.Configuration;
class Program
{
static void Main()
{
// Build a configuration object from environment variables
IConfiguration config = new ConfigurationBuilder()
.AddEnvironmentVariables()
.Build();
// Read configuration values
Console.WriteLine($"Server: {config["Server"]}");
Console.WriteLine($"Database: {config["Database"]}");
}
}
