The following table shows the configuration providers available to. Configuration supports properties, objects, arrays, and dictionaries. The values are accessed using the indexer API where each key is a string, and the value is a string.

Reflection for a complex type that has properties.The TypeConverter for a complex type when the type has one.Direct deserialization (using built-in converters) for primitive types.The binder can use different approaches to process configuration values: In other words, you can use an IConfiguration instance to access any configuration value from multiple providers. These abstractions are agnostic to their underlying configuration provider ( IConfigurationProvider). IConfigurationSection: Represents a section of application configuration values.IConfigurationRoot: Represents the root of an IConfiguration hierarchy.IConfiguration: Represents a set of key/value application configuration properties.This enables the options pattern, which uses classes to provide strongly typed access to groups of related settings.NET configuration provides various abstractions. NET objects and is used with dependency injection. For example, the JSON configuration provider can be used to map appsettings.json files to. NET configuration abstractions is the ability to bind configuration values to instances of. If SomeKey is set in both appsettings.json and the environment, the environment value is used because it was added after appsettings.json. For example, the Command-line configuration provider overrides all values from other providers because it's added last.
