Generating proxy class for the Callback wcf service

Question

Hi,
I have crated the callback wcf service, after that i added the service reference to  the web application.

but  when i create the object for the proxy class it ask

InstanceContext

 

context = new InstanceContext(this);
ProxyClient objProxyClient = new ProxyClient(context);

this code i am writing in the default.aspx.cs page , but it ask for the implemetaion the callback interface in this page.
how to avoid this code in the each aspx page by just creating the proxy object for the service. like Below the code.
ProxyClient objProxyClient = new ProxyClient();

i donot want to remove the callback interface in the wcf servie.
i am using the callback interface for some other control and that is working fine.

only problem with all aspx page to avoid the callback interface in the WEB application.


Thanks,
krishna

Hi,

You have to implement callback interface at the client side (in your example it is default.aspx) in order to handle the callback send by WCF service.

Answer 2

Hi krishna
for WCF callback,
1)you must defined an Iterface in the Service;
2)CLient must impletement the Interface itself,
3)Service owens a reference of the client context,then service can all back;
  I have write a callback demo,you can take it as a refernce.:/Files/frank_xl/WCFServiceOperationFrankXuLei20090503.rar
