Change event queries can be configured through the DbContext, similar to how the EF Core IEntityTypeConfiguration pattern works.

1. Create a configuration class for your change entity that implements the IChangeEventEntityConfiguration<> interface.

   public class UserChangeConfiguration : IChangeEventEntityConfiguration<UserChange>
   {
    public void Configure(ChangeEventEntityConfigurationBuilder<UserChange> builder)
    {
        builder.AddProperty(uc => uc.Name);
        builder.AddProperty(uc => uc.DateOfBirth);
        builder.AddProperty(uc => uc.PrimaryPaymentMethod!.Id.ToString())
            .WithDescription("Primary payment method changed");
    }
   }
   

2. Modify your UseChangeEventQueries() call to include the assembly where your configurations are stored.

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