I'm using WPF with asp.net core as sever, for client & server communications we have implemented signalR framework.

It is connecting seamlessly when I'm running project through Visual studio / development environment. When I take setup for WPF application it throughs below exception shown in screen shot.

I have corrected all the package versions, related to asp.net core, signalR core for client and server, all are under same version specified by Microsoft documentation.

Difference between aspnet SignalR and AspNet Core SignalR

Versions I'm using

Can any one help me on this.

did you check if you can open network port between your servers ? – agua from mars Aug 23 '18 at 12:39
does firewall block access? – magicandre1981 Aug 23 '18 at 15:11
I did specify any port, so it should be 80, which will be always opened – Aravind Koniki Aug 24 '18 at 04:16
Did the client and server on the same computer? Try to make a test with running client on the signalr server to check whether it is related with network. – Edward Aug 24 '18 at 06:51
Yes, Client and server on same computer – Aravind Koniki Aug 26 '18 at 06:23
I found the problem, I have missed some dependencies related to Task extensions while preparing WIX setup for deployment – Aravind Koniki Sep 02 '18 at 09:36
