Call to a specific Client (using Invoke) fails in SignalR - conversion issue?

You don't need to cast it to ClientProxy in order to call Invoke off of it. HubContext.Clients.All. Invoke( method, msg ) is all you need.

Actually, you don't need invoke at all, just hubContext.Clients.All. Method( msg ).

Oeps - found the answer - I need to cast to the IClientProxy - NOT the actual proxy!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
