I'm using XNA 4.0, and I've built a game which will be released for Steam, Impulse and others as well. Now, the thing is that they don't accept ClickOnce deployments since they can't (or can they?) be installed silently.
So I went back to the drawing board, building a Windows Setup project for my XNA project. This works just fine, but when I build the installer, all the content in my content project has been excluded for some reason.
Now, my content project's content normally changes once in a while as I update the game. Therefore, I would hate to add all the content to the setup project manually.
Is it possible to solve this problem by somehow allowing a content project's output files to automatically be included in the installer?
Edit
It's important to keep in mind that I want prerequisites to be installed automatically. It is also a requirement that the installation can run in silent mode.
