Swevo.AutoAudit

Compile-time audit field generation for EF Core entities using Roslyn source generators. Add [Auditable] to any partial entity class and get CreatedAt, UpdatedAt, CreatedBy, and UpdatedBy properties — plus a ready-to-use AuditInterceptor — all generated at build time. Zero reflection, AOT-safe, no runtime overhead.

Installation

dotnet add package Swevo.AutoAudit

Requires EF Core 7+.

Quick Start

1. Mark your entity

using Swevo.AutoAudit;

[Auditable]
public partial class Order
{
    public int Id { get; set; }
    public string? Description { get; set; }
}

The generator adds these properties automatically — no base class required:

// Generated:
partial class Order : IAuditableEntity
{
    public DateTimeOffset CreatedAt { get; set; }
    public DateTimeOffset UpdatedAt { get; set; }
    public string? CreatedBy { get; set; }
    public string? UpdatedBy { get; set; }
}

2. Register the interceptor

// Program.cs / Startup.cs
builder.Services.AddDbContext<AppDbContext>((sp, options) =>
{
    options.UseSqlServer(connectionString);

    // Optional: supply the current user identity
    var httpContext = sp.GetService<IHttpContextAccessor>();
    options.AddAuditInterceptor(() => httpContext?.HttpContext?.User?.Identity?.Name);
});

That's it. CreatedAt/CreatedBy are set on insert; UpdatedAt/UpdatedBy are refreshed on every update.

How It Works

Event	Fields Updated
`Added`	`CreatedAt`, `CreatedBy`, `UpdatedAt`, `UpdatedBy`
`Modified`	`UpdatedAt`, `UpdatedBy`

CreatedAt and CreatedBy are never overwritten on subsequent saves.

Generated Types

The generator emits three shared sources into your project's Swevo.AutoAudit namespace:

Type	Description
`[Auditable]`	The attribute itself
`IAuditableEntity`	Interface implemented by all auditable entities
`AuditInterceptor`	`SaveChangesInterceptor` that applies audit values
`AuditInterceptorExtensions`	`AddAuditInterceptor()` extension for `DbContextOptionsBuilder`

Diagnostics

ID	Severity	Description
`AUDIT001`	Error	Class must be `partial` to use `[Auditable]`

Compatibility

Dependency	Version
EF Core	7.0+
.NET	net7.0+
C#	10+
