Trying to clone a repo from git under VSTS in Visual Studio 2017 but get the following error:
 Git failed with a fatal error. 
 unable to access https://myaccount.visualstudio.com/_git/MyProject/: 
 Proxy CONNECT aborted
Am in a corporate environment with a proxy in place for internet access. Have tried setting the defaultProxy setting in system.net in the devenv.exe.config but makes no difference.
<system.net>
    <defaultProxy useDefaultCredentials="true">
    <proxy proxyaddress="http://proxyurl:8080" bypassonlocal="True" />
</defaultProxy>
Visual Studio 2015 works without issue.
