Need a C# Web Service to call external Web Services. How?
I need to create a back-end web service which then calls a small handful of external web services in order to complete the calculations. Is this a simple task? Using C# to execute an external web service?
How would I call four different such calls at the same time? Does this qualify as "parallel processing"? Anything fancy needed? Or, can I quickly call one after the other, then get a callback for each?
How does this work?
