Hi Archana31,

it is gving "CORS" error at client side

It seems that you try to establish cross-domain connection from your Angular 2 client app, but it causes CORS issue. To solve it, you can try to configure your SignalR hub application to allow the set of origins.

You can check and know how to implement cross-domain connections in SignalR 2 in this article.
