Swevo.EFCore.JsonColumn

NuGet CI

Compile-time JSON column configuration for EF Core 8+. Stamp [JsonColumn] on owned navigation properties and the source generator emits ConfigureJsonColumns(ModelBuilder) so you do not have to hand-write repetitive OwnsOne(..., b => b.ToJson()) boilerplate.

Quick-start

dotnet add package Swevo.EFCore.JsonColumn

1 — Mark JSON-owned navigations

using EFCore.JsonColumn;

public class Address
{
    public string Street { get; set; } = "";
    public string City { get; set; } = "";
}

public class Order
{
    public int Id { get; set; }

    [JsonColumn]
    public Address ShippingAddress { get; set; } = new();
}

2 — Configure your DbContext

public class AppDbContext(DbContextOptions<AppDbContext> options) : DbContext(options)
{
    protected override void OnModelCreating(ModelBuilder modelBuilder)
        => modelBuilder.ConfigureJsonColumns();
}

3 — Generated output

modelBuilder.Entity<global::MyApp.Order>(entity =>
{
    entity.OwnsOne(e => e.ShippingAddress, b => b.ToJson());
});

How it works

  • [JsonColumn] marks an owned reference navigation for JSON-column configuration
  • The incremental source generator scans the full compilation for annotated properties
  • One generated ConfigureJsonColumns(ModelBuilder) method groups properties by owning entity
  • Each property becomes entity.OwnsOne(e => e.PropertyName, b => b.ToJson())

Requirements

  • .NET 8+
  • EF Core 8+
  • JSON-column properties must be reference types

Applying [JsonColumn] to a value type produces warning JSCOL001.
