Wep api hosting using azure service bus

Hi All,

I have a Web api which is self hosted. I want create two Host one using Azure Service Bus and second localhost.

I followed below link to host using Azure service bus but it is giving me error

https://blog.pedrofelix.org/2012/03/15/asp-net-web-api-creating-an-host-using-azure-service-bus/

Error whic I am getting while hosting as Service Bus.

The token provider was unable to provide a security token while accessing 'https://xxxxxxxxx-sb.accesscontrol.windows.net/WRAPv0.9/'. Token provider returned message: 'The request was aborted: The request was canceled.'.

I am using same service bus namespace and token with WCF service and it is working.

Any help will be appreciated.

Thanks
Anita
