Azure SignalR service connection failed with C# Client

Question

My Azure SignalR (serverless mode) service connection getting failed with C# (4.8 .netFramework). My console application consumes Microsoft.AspNet.SignalR.Client and it's dependencies.

Console applicaton code

    private static JwtSecurityTokenHandler jwtTokenHandler;  
    private static HubConnection hubConnection;  
    private static IHubProxy hubProxy;  

static async Task Main(string[] args)  
        {  
            jwtTokenHandler = new JwtSecurityTokenHandler();  
            var serviceUrl = "https://{MyProjectName}.service.signalr.net/client/";  
            var accessKey = "b5Lyzxb+jHzAIb67Sw2+l6BcSArPl57894wreR7I9BtlE=";  
            var hubName = "chathub";            
            var querystringData = new Dictionary

Answer 1

This is expected, as the Microsoft.AspNet.SignalR.Client can only connect to traditional SignalR hubs built upon ASP.NET 4.x. However, Azure SignalR Service is built upon ASP.NET Core SignalR and not compatible with the old client library.

To subscribe to hubs on Azure SignalR Service, you need to use the new library, https://www.nuget.org/packages/Microsoft.AspNetCore.SignalR.Client
