Preload will execute a single command, retrieving all objects in the source enumeration. For example:
//This will fully load all invoice objects in the invoices enumerable. //It is meaningfull only if the invoice objects are Id-initialized //and has not yet loaded full object state. invoices.Preload(); //this will preload all customers of all invoices //however, it is suggested to use Preload(expression) instead. //For Preload(exprssion) see the See also section. invoices.Select(i=>i.Customer).Preload();
