As your tracked entity and change entity will require most of the same properties, it is recommended to create a base class that both will extend. See the samples for an implementation of this.

1. Add the below nuget package to your project:

   EFCore.ChangeTriggers.SqlServer
   

2. Implement the ITracked<> interface on any entity classes that you want to track:

   public class User : ITracked<UserChange>
   {
   ...
   

3. Create a change entity for the tracked entity that implements the IChange<> interface:

   public class UserChange : IChange<User>
   {
   ...
   

4. Add the below assembly attribute to your Program.cs:

   [assembly: DesignTimeServicesReference("EFCore.ChangeTriggers.ChangeTriggersDesignTimeServices, EFCore.ChangeTriggers")]
   

5. Enable ChangeTriggers on your DbContext:

   services.AddDbContext<MyDbContext>(options =>
   {
    options
        .UseSqlServer()
        .UseSqlServerChangeTriggers();
   });
   

6. Auto-configure your change trigger entities in the OnModelCreating() method of your DbContext:

   protected override void OnModelCreating(ModelBuilder modelBuilder)
   {
    modelBuilder.AutoConfigureChangeTriggers();
   ...
   

7. Create a migration to generate the required objects:

   dotnet ef migrations add ChangeTriggers
