Avis de non-responsabilité :Je suis le propriétaire du projet Entity Framework Plus
Cette bibliothèque dispose d'une fonctionnalité Query Future qui permet de regrouper plusieurs requêtes en un seul aller-retour.
Exemple :
// using Z.EntityFramework.Plus; // Don't forget to include this.
var ctx = new EntitiesContext();
// CREATE a pending list of future queries
var futureCountries = ctx.Countries.Where(x => x.IsActive).Future();
var futureStates = ctx.States.Where(x => x.IsActive).Future();
// TRIGGER all pending queries in one database round trip
// SELECT * FROM Country WHERE IsActive = true;
// SELECT * FROM State WHERE IsActive = true
var countries = futureCountries.ToList();
// futureStates is already resolved and contains the result
var states = futureStates.ToList();
