I've had this same SignalR Hub for years now so I've upgraded it and now for some reason it is not generating the client proxies.
Has anyone else run into this issue?
I've updated to the most resent version.
None of my client methods are being generated for some reason, I've tried everything and it must be a new setting that I am missing.
When I first started using SignalR it was a stand alone library now it is integrated with the .NET platform this leads me to believe I have not set something up correctly.
Here is what I've done before I release my solution I've worked on it so long I've got libraries that are 2.0 so I've upgraded all of them to 4.6.2 and this of course has caused a lot of breakage but I have read the docs and it still states I should be able
to
http://localhost:2488/signalr/hubs
and see the client and server methods but the client methods just show an empty array [].
I've got code to help you better understand.

Anywhere you see Clients.Client it does not generate anything.
I realize the return is not necessary but I just recently put it there to see if that would work and it does not, actually I added a return Task type and the return and the bottom of the function but it has never been there before,
it put it there just for a shot in the dark.
PLEASE HELP ME WITH THIS I AM STUCK AT A POINT THAT I CANNOT MOVE FORWARD UNTIL THIS IS WORKING, DUE TO THE FACT THAT MY SOLUTION HEAVLY RELIES ON SignalR.
Thanks to anyone to help me.
I have not done anything to the config files or global file, added anything unusual, I am using it as if it was the very first version that was released, so I am missing something.

It has been a while since I've worked with SignalR and I forgot that SignalR does to create Client side code, the code that calls the server.
It is up to the developer to make sure that function signature on the client side and the server side matches in order for it to work or it will throw an error.
This is a no brainier, but it has been a few years and I am refactoring before i go into production, some of my class libraries were 2.0 but every library / web is the lastest 4.6.2 or 4.5.2.
Do you have a good tool that you can recommend to me to test JSON / AJAX calls from the browser? Like an extension or some other product that I can use with Firefox -> Web Api -> work
Throw new Exception("My Exception Info",ex); error -> Web Api -> FireFox <------- I need this to come back to the browser for testing. It will throw but not back to the browser.
I only use Firefox and IE right now because Google has made some policy changes that are a Hackers dream and they may not realize this but allowing an app from foreign phone or computer to use your phone or computer "Even though it is not on or connected
to be used as a pass-though for a connection or using your devices as a connection point it-self is UNBELIEVABLE" 99.9% of all android users and windows 10 users with Google Chrome do not know the seriousness of this"
Anyway, i wanted to add that because I want this information out on the internet.
**I'm using the latest version of SignalR 2.2.1
Thank you so much for your help.

You could use fiddler to test the request/ response . You could debug the application and use exception filters to handle runtime errors in your Web API :

Hi alumcloud ,
Do you update the signalR to version 2 ? . For details on changes between SignalR 1.x and 2, seeUpgrading SignalR 1.x Projects and Visual Studio 2013 Release Notes. Troubleshooting errors encountered during upgrading , you could see SignalR Troubleshooting.
