DebugLoggerFactoryExtensions	Extension methods for the ILoggerFactory class.
EventLoggerFactoryExtensions	Extension methods for the ILoggerFactory class.
EventSourceLoggerFactoryExtensions	Extension methods for the ILoggerFactory class.
FakeLoggerBuilderExtensions	Extensions for configuring fake logging, used in unit tests.
FilterLoggingBuilderExtensions	Extension methods for setting up logging services in an IServiceCollection.
LogDefineOptions	Options for Define(LogLevel, EventId, String) and its overloads.
Logger<T>	Delegates to a new ILogger instance using the full name of the given type, created by the provided ILoggerFactory.

LoggerFactoryOptions	The options for a LoggerFactory.
LoggerFilterOptions	The options for a LoggerFilter.
LoggerFilterRule	Defines a rule used to filter log messages
LoggerMessage	Creates delegates that can be later cached to log messages in a performant way.
LoggerMessageAttribute	Provides information to guide the production of a strongly typed logging method.
LoggerRedactionOptions	Options to control redaction.

LoggingEnrichmentExtensions	Extensions for configuring logging enrichment features.
LoggingRedactionExtensions	Extensions for configuring logging redaction features.
LogPropertiesAttribute	Marks a logging method parameter whose public properties need to be logged as log tags.
LogPropertyIgnoreAttribute	Indicates that a tag should not be logged.
ProviderAliasAttribute	Defines alias for ILoggerProvider implementation to be used in filtering rules.
TagNameAttribute	Defines the tag name to use for a logged parameter or property.
TagProviderAttribute	Defines a method to invoke to generate logging tags for a referenced object.
TraceSourceFactoryExtensions	Extension methods for setting up TraceSourceLoggerProvider on a ILoggingBuilder.

Structs

EventId

Identifies a logging event. The primary identifier is the "Id" property, with the "Name" property providing a short description of this type of event.

Interfaces

IExternalScopeProvider	Represents a storage of common scope data.
ILogger	Represents a type used to perform logging.
ILogger<TCategoryName>	A generic interface for logging where the category name is derived from the specified TCategoryName type name. Generally used to enable activation of a named ILogger from dependency injection.
ILoggerFactory	Represents a type used to configure the logging system and create instances of ILogger from the registered ILoggerProviders.
ILoggerProvider	Represents a type that can create instances of ILogger.
ILoggingBuilder	An interface for configuring logging providers.
ISupportExternalScope	Represents a ILoggerProvider that is able to consume external scope information.
ITagCollector	Interface given to custom tag providers, enabling them to emit tags.

Enums

ActivityTrackingOptions	Flags to indicate which trace context parts should be included with the logging scopes.
LogLevel	Defines logging severity levels.
