Thanks for your Reply, Please find my comments
I have a single .SVC file which has two service class [Addition/Subtraction] Service.
I have two end points for these two services.
<services>
<service name="AdditionService">
<endpoint address="http://localhost:8080/AdditionService">
binding="basicHttpBinding"
contract="IService" />
</endpoint></service>
<service name="SubtractService">
<endpoint address="http://localhost:8080/SubtractService">
binding="wsHttpBinding"
contract="IService" />
</endpoint></service>
</services>
I want to know, is the way I am approaching is fine or is there any appropriate way of approach, since I am novice to WCF.
