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.

Extension Methods

GetInfrastructure<T>(IInfrastructure<T>)	Gets the value from a property that is being hidden using IInfrastructure<T>. This method is typically used by database providers (and other extensions). It is generally not used in application code.
UseIdentityColumn(ColumnBuilder, Int64, Int32)	Configures the key column to use the SQL Server IDENTITY feature to generate values for new entities, when targeting SQL Server. This method sets the property to be OnAdd.
