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

• Microsoft.Extensions.Configuration.ConfigurationBuilder
