I am trying to deploy a ClickOnce app. It had worked previously when the server was just sitting with .Net 2.0 installed (no SP). Recently the server had 3.5SP1 installed on
In the end my only way of resolving the issue was to create an entirely new project and copy the code over from each form and then publish that.
Jonez: Unfortunately moving my user profile would have been a major hassle and it seemed to me that this would've been major overkill to fix a publishing issue.
Gregory: The installation would fail with that error. I tried publishing to a new location (different physical server) and the issue was still present and I confirmed no ampersands were used in either path.
