Hi,

I have created a DeclarativeServiceLibrary using VS2010 beta 2,
Please check this image of Sequential Service

Following is the code used to call these two activities ` int? data = 123;

        ServiceReference1.ServiceClient client1 = new ServiceReference1.ServiceClient();
        string result1 = client1.GetData(data);

        //This line shows error :(
        string result2 = client1.Operation1();

        Response.Write(result1 + " ::  ::" + result2);`  

client1.GetData works perfectly, but client1.Operation1 show the following error. Please let me know how to fix this.

There is no context attached to the incoming message for the service and the current operation is not marked with "CanCreateInstance = true". In order to communicate with this service check whether the incoming binding supports the context protocol and has a valid context initialized.
