About

Microsoft.Extensions.Configuration is combined with a core configuration abstraction under Microsoft.Extensions.Configuration.Abstractions that allows for building different kinds of configuration providers to retrieve key/value pair configuration values from in the form of IConfiguration. There are a number of built-in configuration provider implementations to read from environment variables, in-memory collections, JSON, INI or XML files. Aside from the built-in variations, there are more shipped libraries shipped by community for integration with various configuration service and other data sources.

Key Features

  • In-memory configuration provider
  • Chained configuration provider for chaining multiple confiugration providers together.
  • Base types that implement configuration abstraction interfaces that can be used when implementing other configuration providers.

How to Use

using Microsoft.Extensions.Configuration;

var configurationBuilder = new ConfigurationBuilder();

configurationBuilder.AddInMemoryCollection(
    new Dictionary<string, string?>
    {
        ["Setting1"] = "value",
        ["MyOptions:Enabled"] = bool.TrueString,
    });

configurationBuilder.AddInMemoryCollection(
    new Dictionary<string, string?>
    {
        ["Setting2"] = "value2",
        ["MyOptions:Enabled"] = bool.FalseString,
    });

var config = configurationBuilder.Build();

// note case-insensitive
Console.WriteLine(config["setting1"]);
Console.WriteLine(config["setting2"]);

// note last in wins
Console.WriteLine(config["MyOptions:Enabled"]);

Main Types

The main types provided by this library are:

  • Microsoft.Extensions.Configuration.ConfigurationBuilder
  • Microsoft.Extensions.Configuration.ConfigurationManager
  • Microsoft.Extensions.Configuration.ConfigurationRoot
  • Microsoft.Extensions.Configuration.ConfigurationSection

Microsoft.Extensions.Configuration.Binder

Provides the functionality to bind an object to data in configuration providers for Microsoft.Extensions.Configuration. This package enables you to represent the configuration data as strongly-typed classes defined in the application code. To bind a configuration, use the Microsoft.Extensions.Configuration.ConfigurationBinder.Get extension method on the IConfiguration object. To use this package, you also need to install a package for the configuration provider, for example, Microsoft.Extensions.Configuration.Json for the JSON provider.
Microsoft.Extensions.Configuration.FileExtensions

Provides a base class for file-based configuration providers used with Microsoft.Extensions.Configuration and extension methods for configuring them.
Microsoft.Extensions.Configuration.Json

JSON configuration provider implementation for Microsoft.Extensions.Configuration. This package enables you to read your application's settings from a JSON file. You can use JsonConfigurationExtensions.AddJsonFile extension method on IConfigurationBuilder to add the JSON configuration provider to the configuration builder.
Microsoft.Extensions.Configuration.EnvironmentVariables

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.
Microsoft.Extensions.Logging.Configuration

Configuration support for Microsoft.Extensions.Logging.
