Namespace Microsoft.EntityFrameworkCore.Metadata

Names for well-known relational model annotations. Applications should not use these names directly, but should instead use the extension methods on metadata objects.

RelationalAnnotationProvider

A base class inherited by database providers that gives access to annotations used by relational EF Core components on various elements of the Microsoft.EntityFrameworkCore.Metadata.IModel.

The service lifetime is Singleton. This means a single instance is used by many Microsoft.EntityFrameworkCore.DbContext instances. The implementation must be thread-safe. This service cannot depend on services registered as Scoped.

RelationalAnnotationProviderDependencies

Service dependencies parameter class for RelationalAnnotationProvider

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Do not construct instances of this class directly from either provider or application code as the constructor signature may change as new dependencies are added. Instead, use this type in your constructor so that an instance will be created and injected automatically by the dependency injection container. To create an instance with some dependent services replaced, first resolve the object from the dependency injection container, then replace selected services using the 'With...' methods. Do not call the constructor at any point in this process.

The service lifetime is Singleton. This means a single instance of each service is used by many Microsoft.EntityFrameworkCore.DbContext instances. The implementation must be thread-safe. This service cannot depend on services registered as Scoped.

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
