Interfaces

IExternalScopeProvider	Represents a storage of common scope data.
IFilterLoggerSettings	Filter settings for messages logged by an ILogger.
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

Enums

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