How do I determine (elegantly) if proxy authentication is required in C# winforms app

Question

My use case is this, I want to call out to a webservice and if I am behind a proxy server that requires authentication I want to just use the default credentials...

Answer 1

System.Net.WebProxy has a property called UseDefaultCredentials that may be what you want (but I have to admit a bit of ignorance here). The link to the relevant documentation is here.
