description for a given WCF service contract. Select the only contract available at this endpoint,

IBasicMath (see Figure 26-21).

Figure 26-21.

Associating a service method to a SendActivity type

Once you do so, you will then be able to pick which operation on the selected contract the

SendActivity should invoke. In our case, the only option is the Add() method (see Figure 26-22).

We have a few additional configuration steps to take before the SendActivity is ready to pass

the values maintained by the FirstNumber and SecondNumber properties to the MathService for pro-

cessing. Specifically, we need to inform the SendActivity which binding will be used during the

invocation by setting a value to the ChannelToken property (recall that a single WCF service can be

configured in such a way that it is exposed from several bindings). If you open the updated App.

config file and locate the  section, you will find that the name of the generated binding is

WSHttpBinding_IBasicMath:

binding="wsHttpBinding" 

bindingConfiguration="WSHttpBinding_IBasicMath"

contract="WFMathClient.ServiceReference.IBasicMath"
