Sharing ServiceStack ICacheClient with SignalR

Sharing ServiceStack ICacheClient with SignalR

I'm trying to share the elements in cache between ServiceStack OOB
ICacheClient and a SignalR Hub, but I'm getting the following error when I
try to get the user session in the OnDisconnected event
Only ASP.NET Requests accessible via Singletons are supported
I have no issues accessing the session in the OnConnected event, so far
this is what I've done:
public class HubService:Hub
{
private readonly IUserRepository _userRepository;
private readonly ICacheClient _cacheClient;
public HubService(IUserRepository userRepository,ICacheClient
cacheClient)
{
_userRepository = userRepository;
_cacheClient = cacheClient;
}
public override System.Threading.Tasks.Task OnConnected()
{
var session = _cacheClient.SessionAs<AuthUserSession>();
//Some Code, but No error here
return base.OnConnected();
}
public override System.Threading.Tasks.Task OnDisconnected()
{
var session = _cacheClient.SessionAs<AuthUserSession>();
return base.OnDisconnected();
}
}
I'm using simple injector and my ICacheClient is registered as singleton:
Container.RegisterSingle<ICacheClient>(()=>new MemoryCacheClient());
the question is how do I register requests as singletons in SS? what am I
missing on SignalR event?
