Methods

BuildSettingsAsync(ConfigurationBuilder, OpenSettingsConfiguration, string, CancellationToken, params Type[])

Builds and configures settings asynchronously for the application based on the specified service configuration.

The BuildSettingsAsync(ConfigurationBuilder, OpenSettingsConfiguration, string, CancellationToken, params Type[]) method handles the initial setup of settings for the application, with behavior changing depending on whether the settings service configuration is set to "Provider" or "Consumer". This method is responsible for syncing application data, generating settings-related files, and adding them to the configuration builder.

The generated settings files are made available through the IConfiguration interface, allowing them to be easily retrieved by the application. This method is typically used during application startup to ensure that settings are properly loaded and integrated into the system.

If the settingsTypes parameter is specified, only the types inherited from ISettings will be treated as settings and managed by the OpenSettings. If no types are provided or if the parameter is null, the library uses reflection to identify and manage all classes inherited from ISettings within the current assembly.

This method is asynchronous and supports cancellation via a cancellationToken. It also accepts optional parameters such as a logger, environment name, and a list of settings types to be configured.

public static Task<IConfigurationBuilder> BuildSettingsAsync(this ConfigurationBuilder configurationBuilder, OpenSettingsConfiguration openSettingsConfiguration, string environmentName = null, CancellationToken cancellationToken = default, params Type[] settingsTypes)

Parameters

configurationBuilder ConfigurationBuilder

The configuration builder used to add the settings to the application's configuration.

openSettingsConfiguration OpenSettingsConfiguration

The settings service configuration determining the behavior (Provider or Consumer).

environmentName string

An optional environment name to customize settings per environment.

cancellationToken CancellationToken

A cancellation token to allow cancelling the operation if needed.

settingsTypes Type[]

The types of settings to build and configure. Only classes inheriting from ISettings will be treated as settings.

Returns

Task<IConfigurationBuilder>

The IConfigurationBuilder

GetSettingOrDefault(IConfiguration, Type)

Retrieves a setting from the configuration or returns the default value if not found.

Retrieves a setting of the specified type from the configuration. If no setting is found, it returns null or the default value of the type.

public static object GetSettingOrDefault(this IConfiguration configuration, Type type)

Parameters

configuration IConfiguration

The IConfiguration used to retrieve the setting.

type Type

The Type of the setting to retrieve.

Returns

object

The setting of the specified type, or null if not found.

GetSettingOrDefault<T>(IConfiguration)

Retrieves a setting from the configuration or returns the default value if not found.

The GetSettingOrDefault<T>(IConfiguration) method retrieves a setting of type T from the configuration. If the setting doesn't exist, it returns the default value for the type. The type T must implement ISettings.

The non-generic GetSettingOrDefault(IConfiguration, Type) method retrieves a setting by the provided type. If no setting is found, it returns null or the default value of the specified type.

public static T GetSettingOrDefault<T>(this IConfiguration configuration) where T : ISettings

Parameters

configuration IConfiguration

The IConfiguration used to retrieve the setting.

Returns

T

The setting of the specified type, or the default value if not found.

Type Parameters

T

The type of setting to retrieve, which must implement ISettings.
