J'utilise NHibernate avec Velocity comme second fournisseur de niveau de cache.NHibernate avec Appfabric Velocity se bloque après la suppression de la région
Je dois effacer une zone. J'utilise ce code:
_sessionFactory.EvictQueries("Authorization");
var authCache = _sessionFactory.GetSecondLevelCacheRegion("Authorization");
authCache.Clear();
authCache.Clear() appelle en fait la méthode NHibernate.Caches.Velocity.VelocityClient.Cache.
La zone est effacée correctement. Mais juste après cela, une nouvelle session est ouverte et une requête est faite contre une entité précédemment mise en cache. Il essaie de GetAndLock dans VelocityClient. Coup. Le AppFabricCachingService se bloque (voir le journal des événements ci-dessous)
Est-ce que je vide le cache correctement? Quelle est mon erreur?
