Menistar.EntityFrameworkCore.SoftDelete 5.0.1

Enable soft delete for DbContext

Enable the soft delete extention for a DbContext by calling the extention method UseSoftDelete in the constructor of the DbContext. Because extention methods are only available on object instance you have to use this.

public class ApplicationDbContext : DbContext
{
    public ApplicationDbContextDbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
        this.UseSoftDelete();  
    }

    public DbSet<Blog> Blogs { get; set; }
    public DbSet<Post> Posts { get; set; }
    public DbSet<Comment> Comments { get; set; }
    
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
    }
}

Configure soft delete for a entity type

Soft delete must be configured for every specific entity in the model by calling the extention method HasSoftDelete on the entity builder. The method contains a overload to use a specific property of the entity. The type of the property must be DateTime?.

public class ApplicationDbContext : DbContext
{
    public ApplicationDbContextDbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
        this.UseSoftDelete();  
    }

    public DbSet<Blog> Blogs { get; set; }
    public DbSet<Post> Posts { get; set; }
    public DbSet<Comment> Comments { get; set; }
    
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        
        // Configure soft delete for blogs using the default shadow property.
        builder.Entity<Blog>()
             .HasSoftDelete();
                        
        // Configure soft delete for comments by specifying a property of type DateTime? on the Comment entity to use.
        builder.Entity<Comment>
            .HasSoftDelete(c => c.DeletedAt);      
    }
}

(Optional) Add a migration containing the changes to your model
