ClickOnce and Proxy Authentication

[Jason Hanford-Smith]

Hi all,

Hopefully this is the right group to post this to.

Anyway, I've written an application that I'm deploying via ClickOnce. Some
people have informed me that they are unable to install the application.
They get the message below. My question is, can ClickOnce be configured to
use the user's IE Proxy Settings when installing?

Hi Jason,

Thanks for your post.

For this issue, it has been confirmed as a known issue of Whidbey. The root
cause is that .Net deployment API did not use the default proxy and
credentials to access the remote clickonce files.

To workaround this issue, we can set useDefaultCredentials to true in
machine.config, like this:
<defaultProxy enabled="true" useDefaultCredentials="true">

The official bug link is:
