Wout, you should look at the comment thread here: http://kennyw.com/indigo/143

So if I understand correctly, there is no way to specify username/password just for the http proxy like it worked in .NET 2.0 (things did work and also understandably back then!). Why was this behavior broken?

If your IE settings are correct for hitting the terra server, then you shouldn’t need any specific WCF proxy settings. The default of “UseDefaultWebProxy = true” will simply use the settings from IE by default

I'm new to WCF and am trying to get a handle on LINQ via the walkthrough in MSDN which connects to http://terraserver.microsoft.com/TerraService2.asmx. However I am behind a corporate ISA firewall/proxy that requires authentication. I can surf the web with IE just fine so my default proxy settings are OK. but the following app.config settings still fail with: (407) Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied). The settings are the auto-generated ones with proxyCredentialType="Windows". I also added the impersonate bit just in case - not sure if it's relevant though. I assume I am not setting the proxy credentials correctly and would appreciate any pointers on how to do this...

[...] In my earlier post on HTTP proxies I noted that all of our transport security implementations (including HTTP proxy authentication) leverage the shared WCF-wide credential provisioning framework. As a result, it’s pretty straightforward to configure your proxy credentials. I think what trips people up is that we don’t have a separate “ProxyCredentials” object. Rather, both the proxy authentication and the ultimate server authentication access credentials from the same location (such as ChannelFactory.Credentials). [...]

I’d need to see you configuration (it seems to have gotten stripped in the comment) to know for sure. If you have the default settings then you will use what’s in IE. Otherwise you need to remember to set defaultWebProxy=false as well as setting proxyAddress=”http://myProxy” from within your config on the basicHttpBinding or wsHttpBinding.

I am having the same issue. It ignores proxy settings and connects without the proxy. Here is my client configuration:

Hmm, we’ve verified these settings in many different configurations. I’ll take a look at your code.

I was playing with these settings a while back, trying to get a proxy-based trace utility to work, and in every case it seemed to ignore my new settings. Any ideas?
