Preloadable elements are values of delayed-loading properties, which have the ability to be fast-preloaded before accessing them for lists of objects.

Remarks

Delayed-loaded properties are properties, which load their value for some object upon first access. Preloading is performance technique, used for delayed-loaded properties, which allows mass loading of the values of such properties.

The primary usage of preloading is before accessing a delay-loaded property in a loop. For example:

Copy
//.CustomProperties is a delay-loaded property
customers.Preload(c => c.CustomProperties);

//this will run fast, because .CustomProperties are preloaded
foreach(var c in customers)
{
  Console.WriteLine(c.CustomProperties);
}
