Remarks

This class is typically inherited by database providers to customize the SQL generation.

The service lifetime is Scoped. This means that each DbContext instance will use its own instance of this service. The implementation may depend on other services registered with any lifetime. The implementation does not need to be thread-safe.

See Database migrations for more information and examples.
