C# Web Service Client using a CookieContainer

Question

I have developed a small C# form application which calls a web service. Everything works nicely but I need to keep state and to do that I need to use a CookieContainer if I am not mistaken.

I created the Service Reference by using the "Add Service Reference" menu of my project and everything worked nicely. But I do not know how to add a CookieManager on the created client.

I found some examples that were showing samples like:

serviceClient.CookieContainer=new CookieContainer()

but this is not the case. My service client does not have such a property. I am suing Visual Studio 2010 Beta by the way.

Thank you in advance!

This is the resulted ServiceReference(which was automatically created):

Answer 1

Quoted: If an XML Web service method uses session state, then a cookie is passed back in the response headers to the XML Web service client that uniquely identifies the session for that XML Web service client. In order for an XML Web service to maintain session state for a client, the client must store the cookie.

Answer 2

This service reference in created using WCF and WCF is independent of the actual medium of communication that means these services can be used either using webservice or remoting or MSMQ. And remoting and MSMQ doesn’t have a concept of Cookies.

Better create your web service reference using WSDL.exe and add the resulting class in your project. I did the same thing.
