Npgsql Source Generators

Registering all enums one by one is tedious. Use this.

Usage

Place [PostgresEnum] attribute on the enums you want to register...

namespace MyCoolApp;

[PostgresEnum]
public enum Status {
    Completed,
    InProgress,
    Started,
    Queued
}

[PostgresEnum(Name = "process_priority")]
public enum Priority {
    High,
    Medium,
    Low
}

...and register them

var source = new NpgsqlDataSourceBuilder(connectionString).npgSourceBuilder
    .MapPostgresEnums()
    .Build();
services.AddDbContext<MyDbContext>(options => options.UseNpgsql(source));

public class MyDbContext : DbContext
{
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        builder.RegisterPostgresEnums();
    }    
}

Tip

In Npgsql 9.0, you can use just this instead of the previous two

builder.Services.AddDbContext<MyContext>(options => options.UseNpgsql(
    "<connection string>",
    o => o.MapPostgresEnums()));
