What is the syntax for including multiple navigation properties in Entity Framework?

Use

Include("Worker").Include("StatusType")

Or if it is a subproperty of the property you are including try

.Include("Worker.StatusType")

for example we have two class :

public class Address 
{
 [Required]
 public int ProvinceId { get; set; }

 [ForeignKey(nameof(ProvinceId))]
 public Province Province { get; set; }

}

public class Province 
{
 [StringLength(50)]
 [Required]
 public string Name { get; set; }
}

 //Now if you want to include province use code below : 

 .Include(x => x.Address).ThenInclude(x => x.Province)
