WCF Proxy Authentication Required（407）
When I’m in the office, I have to use an authenticated proxy to get outside our intranet and to the internet. When I called a service that resides on the web, I got the 407 error. How can we fix this without having to provide an account to our application
The answer is actually pretty simple. The answer has nothing to do with WCF, but everything to do with System.Net.
System.Net’s default web proxy does not have the UseDefaultCredentials flag switched on by default. It’s false. Creating a new WebProxy object with the flag set to true is problematical… it turns out to be quite hard to find out the address and port of the default web proxy at runtime, because this is essentially a dynamic thing, and not (as previously thought in the .NET 1.x era) a static thing.
So by far the best thing to do is use your app’s App.Config file to tell System.Net to use the default credentials for authentication to an HTTP proxy server. Something like this:
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy autoDetect="True"/>
</defaultProxy>
</system.net>
