EF.Audit.Core

Easy audit capabilities for EF core projects.

Auditable Entities

First of all, you need to mark all your auditable entities using Auditable and NotAuditable attributes.

Auditable: Can be used to mark a class (including all properties without object references ). NotAuditable: Marks a property as not auditable.

Enable Audit

Install EF.Audit.Core nuget package. You have two way to use it 1 - Your dbcontext will inherit the AuditContext and adds services required for using AuditContext. services.AddAudit();

[Auditable]
public class Blog
{
    public Blog()
    {
        Posts = new List<Post>();
    }
    public int BlogId { get; set; }
    public string Url { get; set; }

    public List<Post> Posts { get; set; }
}

[Auditable]
public class Post
{
    public int PostId { get; set; }
    public string Title { get; set; }
    public string Content { get; set; }

    public int BlogId { get; set; }
    public Blog Blog { get; set; }
}

public class BloggingContext : AuditContext
{
    public DbSet<Blog> Blogs { get; set; }
    public DbSet<Post> Posts { get; set; }

    public BloggingContext(Func<AuditUser> fn, DbContextOptions<BloggingContext> options) :base(fn,options)
    {
    }
      
}

2 - Other way is using extension method EnableAudit and SaveChangesAndAudit or SaveChangesAndAuditAsync

public class BloggingContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }
    public DbSet<Post> Posts { get; set; }
    public BloggingContext(DbContextOptions<BloggingContext> options) :base(options)
    {
    }
      
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.EnableAudit(); 
    }
} 

var blog = new Blog { Url = "http://blogs.msdn.com/adonet" };
var count = context.SaveChangesAndAudit();
