I\'ve created a Windows C# project and made it as ClickOnce Application(Publish feature in Project properties) for Installation.
I want to Include a folder<
It's been a long time since the OP, but when I add a folder to my solution, add a Crystal Report to that folder and mark it as "Content" (per Tom), then Publish and install - the folder and report gets added to the ClickOnce installation location. So Tom's solution worked for me.
