I have installed NAV 2013 to consume web services using C# in VS 2012, I have published a page Purchase Order in web service even I can access pretty well in browser but when I try to access properties "UseDefaultCredentials" & other class like Purchaseorder_service after adding it in Web Reference. I check all configurations I found all are fine.
Is it because, I haven't created any SPNs but I remember back in 2009 without SPNs we couldn't access the web service itself but I can do it.
Please suggest if you have clue why this is not working?
