About

Environment variables configuration provider implementation for Microsoft.Extensions.Configuration. This package enables you to read configuration parameters from environment variables. You can use EnvironmentVariablesExtensions.AddEnvironmentVariables extension method on IConfigurationBuilder to add the environment variables configuration provider to the configuration builder.

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"]}");
    }
}
