Q:

Determine transport method in SignalR Core?

In SignalR 2.0 the transport method can be determined by the transport parameter in the query string.
string transportMethod = queryString["transport"];

This doesn't seem to be the case in SignalR for ASP.NET Core.  
The best I can do, it seems, is to use header information.
For WebSocket connections:
Connection = Upgrade
Upgrade = Websocket

And long polling:
Connection = Keep-Alive

And server-sent events:
Connection = Keep-Alive
Accept = text/event-stream

Is there a better/easier way to go about determining the transport method?

A:

You can get the transport type from the HubCallerContext like so
 Context.Items[ConnectionMetadataNames.Transport]
