Remarques

Le même code d’assembly utilise différents magasins isolés lorsqu’il est utilisé dans le contexte de différentes applications.

GetUserStoreForDomain est fonctionnellement équivalent au code suivant :

isoFile = IsolatedStorageFile::GetStore(IsolatedStorageScope::Assembly |
    IsolatedStorageScope::Domain | IsolatedStorageScope::User,
    (Type^)nullptr, (Type^)nullptr);

isoFile = IsolatedStorageFile.GetStore(IsolatedStorageScope.Assembly |
    IsolatedStorageScope.Domain | IsolatedStorageScope.User,
    null, null);

isoFile = IsolatedStorageFile.GetStore(IsolatedStorageScope.Assembly Or _
    IsolatedStorageScope.Domain Or IsolatedStorageScope.User, _
     Nothing, Nothing)

Différents assemblys s’exécutant dans le même domaine d’application ont toujours des magasins isolés distincts.
