SignalR - How do I disable WebSockets

Question

I upgraded to .NET 4.5, now SignalR seems insistent on using WebSockets in Firefox/Chrome - even though I\'m only on Windows 7 which doesn\'t have a WebSocket Server.

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", options =>
        {
            options.Transports =
                HttpTransportType.WebSockets |
                HttpTransportType.LongPolling;
        });
    });
}
