Microsoft.Extensions.Configuration.Abstractions 9.0.0-preview.6.24327.7

About

Provides abstractions of key-value pair based configuration. Interfaces defined in this package are implemented by classes in Microsoft.Extensions.Configuration and other configuration packages.

Key Features

• Abstractions for string key-value pair configuration sources and sections
• Path conventions of keys establishing a heirachy of values
• Support for multiple configuration sources, aggregating and defining precdence for values
• Support for reload on change

How to Use

The example below shows a small code sample using this library and trying out the ConfigurationKeyName attribute available since .NET 6:

public class MyClass
{
    [ConfigurationKeyName("named_property")]
    public string NamedProperty { get; set; }
}

Given the simple class above, we can create a dictionary to hold the configuration data and use it as the memory source to build a configuration section:

var dic = new Dictionary<string, string>
{
    {"named_property", "value for named property"},
};

var config = new ConfigurationBuilder()
    .AddInMemoryCollection(dic)
    .Build();

var options = config.Get<MyClass>();
Console.WriteLine(options.NamedProperty); // returns "value for named property"
