I'm trying to implement some server-side methods but not sure how to get to MEF Composition container
 
public class ServerMethods
    {
        [Import]
        public IPushNotificator PushNotificator { get; set; }
        [AllowRpc]    
        public static void PushToDevices(IPrincipal principal, EntityManager entityManager, params object[] args) 
        {          
            return;
        }
    }
 
I need to access my PushNotificator from PushToDevices methods. Server-side method is static and I don't get PushNotificator. How do I access this object in my scenario?

Hi katit,
In this case you might want to try access it within the method itself:
 
  [AllowRpc]
  public static void PushToDevices(IPrincipal principal, EntityManager entityManager, params object[] args) {
    var pushNotificator = IdeaBlade.Core.Composition.CompositionHost.Instance.GetExportedInstance<IPushNotificator>(false);
  }
 
The cause of the issue might be that because ServerMethods is never instantiated, there isn't an instance of it to be referenced by the static method.
 
Regards,
   Silvio.

Yes, sure it's not in Static. Actually, it's not in  IdeaBlade.Core.Composition.CompositionHost either.
 
I got it from my own Bootstrapper class..
