ModelBuilderExtensions

Contains extension methods for configuring common Entity Framework Core model relationships and navigation behavior. The methods are intended to be called from OnModelCreating and keep repeated fluent API chains in one place.

Use these extensions when a relationship follows the package's supported shapes and the default WithOne() or WithMany() side is enough for the model. If a relationship needs a custom inverse navigation, additional constraints, or advanced EF Core mapping behavior, use EF Core's fluent API directly for that case.

Usage

using Microsoft.EntityFrameworkCore;
using AlmightyShogun.EntityFrameworkCore.Utils;

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.ApplyManyToOne<User, UserSession>(
        session => session.User,
        session => session.UserId
    );
}

Methods

• ApplyAutoInclude — configures a navigation to be automatically included in queries.
• ApplyManyToOne — configures a dependent-to-principal reference relationship.
• ApplyOneToMany — configures a principal-to-dependent collection relationship.
• ApplyOneToOne — configures a principal-to-dependent reference relationship.
