Multiple hub, single hub dispose error

Question

User-1117888163 posted

Let's suppose I have client and server sides of hubs and I make connection to communicate with each other. Client side always listen to server(you can asuume that, send and receive messages between them) I am also able to create new another hub except mainhub. We create second hub because we dont want mainhub gets busy, we use second hub for send big stack of data from client to server or opposite. When second hub finish its transaction, we stop to secondhub run. The issue is when I stop it, client connection get lost in mainhub then client reconnect to mainhub by itself. I want client always keep connect to mainhub even I stop to secondhub`s run.

Hi atlanti,

According to your description, as far as I know, about how to keep connect multiple hubs and disconnect form one. You could refer to the following tutorials:

How to handle connection lifetime events in the Hub class: 

https://docs.microsoft.com/en-us/aspnet/signalr/overview/guide-to-the-api/hubs-api-guide-server#how-to-handle-connection-lifetime-events-in-the-hub-class

Connected to multiple hubs and disconnect from only one:

Hi Eric,

I could not find a similar code example in my algorithm construction, although I have examined all the examples in there. If you look at the fact I can not fully explain the problem. I am opening the first hub connection in a single server windows form application, then I open the second hub connection. I want to turn it off when the second hub connection is done. But the first hub is reconnecting. I do not do anything with the first hub.

I also created a question title here : https://stackoverflow.com/questions/45673968/c-sharp-signalr-multiple-hub-single-hub-dispose

Thank you for your interest,
