Bonjour,

J'éprouve des difficultés à taguer mes entités avec des [DataContract(IsReference=true)]

Voici mon model objet :

[DataContract(IsReference=true)]
public abstract class Entity<idT> : IEntity<idT>
{
    public idT Id { get; set; }
}
 
[DataContract(IsReference=true)]
public class Todo : Entity<int>
{
    public virtual string Title { get; set; }
    public virtual string Description { get; set; }
    public int Version { get; set; }
    public virtual DateTime CreationDate { get; set; }
    public virtual DateTime UpdateDate { get; set; }
    public virtual Category Category { get; set; }
}
 
[DataContract(IsReference=true)]
public class Category : Entity<int>
{
    public virtual string Name { get; set; }
    public virtual IList<Todo> Todos { get; set; }
}

- Quand je tag Category et Todo de [DataContract(IsReference=true)] j'ai une erreur disant que la classe de base doit aussi avoir un Tag DataContract
- Quand je rajoute le tag [DataContract] sur ma classe Entity<T> cela ne marche toujours pas car il faut avoir IsReference a true sur toute la chaine
- Quand je rajoute le tag [DataContract(IsReference=true)] sur ma classe Entity<T> j'ai une erreur lors de la génération de mon Proxy de service (application silverlight 4) :

Bon j'avoue ne pas comprendre ... Si quelqu'un a une idée je suis ouvert !

Merci

Bon je vais essayer ce soir avec une classe EntityInt au lieu de Entity<int>, si ça marche j'ai un peu les boules car ça casse mon modele ...

[anthyme]

Bon j'ai trouvé la solution !

Voici comment taguer la classe générique :

[DataContract(Name = "EntityOfType{0}", IsReference = true)]
