Class NpgsqlValueGenerationConvention

Namespace

Npgsql.EntityFrameworkCore.PostgreSQL.Metadata.Conventions

Assembly

Npgsql.EntityFrameworkCore.PostgreSQL.dll

A convention that configures store value generation as OnAdd on properties that are part of the primary key and not part of any foreign keys, were configured to have a database default value or were configured to use a NpgsqlValueGenerationStrategy. It also configures properties as OnAddOrUpdate if they were configured as computed columns.
