Is the Web Service SOAP or RESTFul?
Elaborate how the service reference added to the project (for SOAP Service).
#Step 1
Make sure that the web site application is compiled successfully.
#Step 2
Delete service reference (for SOAP service)
#Step 3
Build the project succesfully by addressing any exceptions
#Step 4
Add service reference by choosing 'Add Service Reference' context menu.
#Step 5
Build the solution and post any issues here.
Note that it is NOT required to add service reference for RESTFul service.
