Stop Blazor SignalR from sending requests to Azure SignalR

[robinqueen]

Is your feature request related to a problem? Please describe.

I am trying to run a Blazor web app with Azure SignalR and I noticed the connected clients is quite large when theres minimal traffic. I notice there is a basehub connection, as well as a componenthub connection. To my understanding the componenthub is the Blazor SignalR instance.

Describe the solution you'd like

Is there a way to separate or filter these requests, so in this case the blazor component hub requests would stay in blazor signalr, and in this case, if basehub were say decorated with an attribute of [UseAzureSignalR] it would proxy it via azure?

What I am asking could very well exist or entirely not be possible also - just wasn't sure of the feasibility of this feature.

It is currently not supported. Under the hood, Azure SignalR replaces the entire HubLifetimeManager so it seems hard to serve different settings. One idea to workaround the issue is to use 2 separate servers, one for blazor app and one for the normal hub.

Thanks @vicancy We will review the pricing of azure signalr and determine if this approach would be feasible once we hit that cost cutoff.
