Ever since upgrading to Visual Studio 2010, I\'m running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds befor
Instead of turning off the proxy setting altogether you can try using the bypasslist to turn it off for the servers that you're having problems with.
See http://msdn.microsoft.com/en-us/library/kd3cf2ex.aspx for details and a sample.
If you're having problems changing the app.config I suggest posting the errors and possibly the app.config as well.
Brent - that's the correct solution : adding a defaultProxy element to your application's configuration file.
So for a website, it's the web.config. For an .exe application, it's .config.
And those settings are also correct :-
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy enabled="false" useDefaultCredentials="false">
<proxy/>
<bypasslist/>
<module/>
</defaultProxy>
</system.net>
</configuration>
