Accessing SignalR Hub from ASP.Net core which is created in ASP.Net

Im trying CORS.

SignalR server is created in ASP.Net using this link . And im trying to access the Hub from ASP.Net Core client application using "@aspnet/signalr-client". My question is

1.  Is this possible?.
2. If possible, how the "/signalr/hub" js will be used in asp.net core.

I tried this and got this error when i call .start();

im trying to connect the Hub from type script code. if i use normal jquery in index.chtml then it gets connected. Is this possible from type script

my index.chtml code

@section scripts {    <script src="~/dist/main-client.js" asp-append-version="true"></script>    <!--Reference the autogenerated SignalR hub script. -->    <script src="http://localhost:52527/Scripts/jquery-1.10.2.min.js"></script>    <script src="http://localhost:52527/Scripts/jquery.signalR-2.0.3.min.js"></script>    <script src="http://localhost:52527/signalr/hubs"></script>    <script>        $(function () {                        $.connection.hub.url = "http://localhost:52527/signalr/ChatHub"            // Start the connection.            try {                $.connection.hub.start({ transport: 'longPolling' }).done(function () {                    console.log('Hub connection started');                });            }            catch (error) { console.log('Error while establishing connection', error);}        });    </script>}

my home.component.ts code

ngOnInit() {        this._hubConnection = new HubConnection('http://localhost:52527/chatHub', { transport: TransportType.LongPolling, logging: LogLevel.Information });        console.log(this._hubConnection);        this._hubConnection.on('Send', (data: any) => {            const received = `Received: ${data}`;            this.messages.push(received);        //});        this._hubConnection.start()            .then(() => {                console.log('Hub connection started')            })            .catch((error) => {                console.log('Error while establishing connection' , error)            });    }

Thanks in advance.
