Enable cross domain not a member of hubConfiguration - vb.net

Question

i have been developing a signalR chat application in vb.net where i'm using the below code:
Public Sub Configuration(ByVal app As IAppBuilder)
Dim config = New HubConfiguration With {.EnableCrossDomain = True}
app.MapHubs(config)
End Sub
it throws the error
Enable cross domain not a member of hubConfiguration
Could anyone please suggest what could be the alternative to enable Cross Domain

The tutorial is explaining this very good:
(http://www.asp.net/signalr/overview/guide-to-the-api/hubs-api-guide-javascript-client)
public class Startup
{
public void Configuration(IAppBuilder app)
{
// Branch the pipeline here for requests that start with "/signalr"
app.Map("/signalr", map =>
{
// Setup the CORS middleware to run before SignalR.
// By default this will allow all origins. You can
// configure the set of origins and/or http verbs by
// providing a cors options with a different policy.
map.UseCors(CorsOptions.AllowAll);
var hubConfiguration = new HubConfiguration
{
// You can enable JSONP by uncommenting line below.
// JSONP requests are insecure but some older browsers (and some
// versions of IE) require JSONP to work cross domain
// EnableJSONP = true
};
// Run the SignalR pipeline. We're not using MapSignalR
// since this branch already runs under the "/signalr"
// path.
map.RunSignalR(hubConfiguration);
});
}
}
}
By the way: In the case you post your code (all) it is easier to search.
