Lazy Loading:- By Default Linq support lazy loading. in this techniq the Child objects are not loaded automatically with Parent object. until they are requested.
var query = context.Employees.Take (4); // Lazy loading
Eager Loading:- in case of eager loading the child objects are loaded automatically with parent object.
if we want to use eager loading then we need to use Inclue method.
var query = context.Employees.Include(“Products”).Take(4); // Eager loading
Explicit Loading:- when lazy loading is turn off. we can also load related entites by explicit calling by load method.
dbContext.Entry(usr).Reference(usr => usr.UserDetails).Load();
