Query Entitiy Framework cache

Question

Is it possible to perform an explicit Where query on the Entity Framework cache? I know that I can use Find to look for an entity in the cache (based on the entities primary key).

Code sample:

var person = new PersonToStoreInDb() { Id = 1, Name = "John" };
dbSet.Add(person);
// Perform some other code
...
// DbContext.SaveChanges was NOT called!
var personFromDbSet = bSet.Where(p => p.Name == "John").First();
// personFromDbSet is null because it was not sent towards DB via SaveChanges

Entity Framework manages the cached data in DbSet.Local. It is an observable collection and Linq queries like Where can be applied to it. It will contain the loaded entries as well as entries of different state like added and removed until SaveChanges is called.
