Microsoft.Extensions.Configuration 10.0.0-preview.1.25080.5

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"]);
