AutoDbSet

Automagically add DbSet<T>s to your DbContext

Usage

Place [AutoDbSet] attribute on the database models you want to register...

using AutoDbSetGenerators;

namespace AutoDbSet.Demo;

[AutoDbSet]
public class Person
{
    public required string Name { get; set; }
    public required DateOnly Birthday { get; set; }
    public required float Height { get; set; }
}

Place [AutoDbContext] attribute on your DbContext and make it partial...

using AutoDbSetGenerators;
using Microsoft.EntityFrameworkCore;

namespace AutoDbSet.Demo;

[AutoDbContext]
public partial class MyCoolDbContext : DbContext
{
}

And watch the magic happen!

namespace AutoDbSet.Demo;

[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute]
[global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]
[global::System.CodeDom.Compiler.GeneratedCode("AutoDbSet", "2.0.0.0")]
public partial class MyCoolDbContext
{
    public required Microsoft.EntityFrameworkCore.DbSet<AutoDbSet.Demo.Person> Persons { get; init; }
}

DbSet naming

By default AutoDbSet will try to naively pluralize the names (here's how). It does not, therefore, work with verbs that have irregular plural form, nor does it work with non-English languages.

You can, however, give the sets your own, custom name:

[AutoDbSetGenerators.AutoDbSet(Name = "People")]
public class Person
{
    public required string Name { get; set; }
    public required DateOnly Birthday { get; set; }
    public required float Height { get; set; }
}

will generate

namespace AutoDbSet.Demo;

[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute]
[global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]
[global::System.CodeDom.Compiler.GeneratedCode("AutoDbSet", "1.0.0.0")]
public partial class MyCoolDbContext
{
    public required Microsoft.EntityFrameworkCore.DbSet<AutoDbSet.Demo.Person> People { get; init; }
}

Multiple DbContexts support

You can relate a given class to a given DbContext using the DbContext property of the [AutoDbSet] attribute:

[AutoDbSetGenerators.AutoDbSet(DbContext = typeof(MyCoolerDbContext))]
public class CoolerPerson
{
    public required string Name { get; set; }
    public required DateOnly Birthday { get; set; }
    public required float Height { get; set; }
    public bool IsCool { get; } = true;
}

Classes without an explicit DbContext will be registered to the single DbContext that was not specified in any other [AutoDbSet] attribute.

ExpressiveSharp support

AutoDbSet supports ExpressiveSharp out of the box, and generates ExpressiveDbSet<T>s instead of DbSet<T>s if it's available.
