We all know how annoying it is working somewhere with a proxy server that requires authentication, especially as Microsoft increasingly don’t support the scenario with many of their Azure-related tools. However, it is quite possible to use authenticated proxies with .NET applications including Powershell.
For the former, edit the application .config file and add
<system.net> <defaultProxy useDefaultCredentials="true" /> </system.net>
And for Powershell, add the following to your scripts or $profile
$proxyString = "http://proxy:8080" $proxyUri = new-object System.Uri($proxyString) [System.Net.WebRequest]::DefaultWebProxy = new-object System.Net.WebProxy ($proxyUri, $true) [System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultCredentials
