I built server and client code that uses SignalR. The website is working perfectly, but I can't see the web traffic in any browser (chrome, IE, Firefox). I know the web traffic is there because the website is working.
Is there a way to view SignalR Traffic in a browser? If not what is the best external tool for viewing SignalR traffic?
Yes, you can view SignalR traffic in Developer Tools (Tested with Chrome).
Open Network Tab.
Click on "WS" to filter out all except Web Socket traffic.
Refresh Page. You will see something like this that shows you the connection was established. Note that you will only see this one line as it only shows that the web socket was connected. Additional traffic is not shown here like you might expect (see below)
you can use Fiddler, see this article :
