SignalR - How do I disable WebSockets

I found the answer here:

https://github.com/SignalR/SignalR/wiki/SignalR-JS-Client

Basically:

$.connection.hubs.start({ transport: 'longPolling' }, function() {
    console.log('connection started!');
});

In order to disable a transport on the server side, you must use something like this:

using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Transports;
using Owin;
namespace MyApplication
{
    public static class Startup
    {
        public static void ConfigureSignalR(IAppBuilder app)
        {
            // If using the global dependency resolver
            TurnOfForeverFrame(GlobalHost.DependencyResolver);
            app.MapSignalR();
        }
        public static void TurnOfForeverFrame(IDependencyResolver resolver)
        {
            var transportManager = resolver.Resolve<ITransportManager>() as TransportManager;
            transportManager.Remove("foreverFrame");
        }
    }
}

The @reach4thelasers' solution only disable it in the client, but the client could re-enable the transport and connect.

Cheers.

For anyone looking how to disable it on the server using asp.net core 3.1:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapHub<ChatHub>("/chathub", options =>
        {
            options.Transports =
                HttpTransportType.WebSockets |
                HttpTransportType.LongPolling;
        });
    });
}
