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
