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"
Main Types
The main types provided by this library are:
- Microsoft.Extensions.Configuration.IConfiguration
- Microsoft.Extensions.Configuration.IConfigurationBuilder
- Microsoft.Extensions.Configuration.IConfigurationProvider
- Microsoft.Extensions.Configuration.IConfigurationRoot
- Microsoft.Extensions.Configuration.IConfigurationSection
