Q:

Receive wcf Callback in Asp.net Core application

I am having a Duplex WCF Service hosted on console. This is tested and worked fine.
I want to consume this WCF service in Asp.net Core. I have done this using this https://medium.com/@narinkaew/using-wcf-soap-services-in-net-core-fb13180c4eda Consume WCF in Asp.net Core.
I am able to get response, but I am not getting any callback. Its just keep waiting.
I have uploaded the Code https://filebin.net/pf9eplqjncc0octj.
ClinicWcfService - is wcf Service Application
HospitalServiceHost - WCF Service Hosted on Console
ServiceEngineersDesk - is Asp.net Core Application.
Can someone tell me how to get a WCF callback in asp.net core application?

A:

I have done this from my side.
Instead of creating instance of interface of the wcf service, create a instance of interface implementation. 
Now this class exposes the event of the callback. Just subscribe to it
After a some struggle i was able to found out.
