WCF aspNetCompatibilityEnabled = "true" genera un'eccezione (impossibile caricare)

Question

Ho bisogno di abilitare le sessioni nel mio servizio WCF. Quindi devo:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 

Quando faccio che ottengo un'eccezione:

Il servizio non può essere attivato perché non supporta ASP.NET compatibilità. La compatibilità ASP.NET è abilitata per questa applicazione. Disattivare la modalità di compatibilità ASP.NET nel web.config o aggiungere l'attributo AspNetCompatibilityRequirements al tipo di servizio con impostazione RequirementsMode come 'ammessi' o 'required'

Questo è il mio web.config:

    <assemblies> 
    <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 

Answer 1

Esempio:

namespace WcfService1 
{ 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] 
    public class Service1 : IService1 
    { 

Answer 2

Hai provato ad aggiungere il seguente attributo alla tua classe di servizio?

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 

È possibile quindi utilizzare il HttpContext per accedere alla sessione in questo modo:

HttpContext.Current.Session
