I was just calling a service reference method, I noticed that the method has a lot of parameters in its signature, Whereas there exists a request class related to the same service.
If I'm not making mistake in calling method so why there is a request model?
var client = new AtlasjetClient();
var result = await client.airportsListAsync("USER", "PASS");
the result
is type of airportsListResponse
but there is also a airportsListRequest
class in service reference. WHY?
