ClickOnce and application data

I am trying to deploy an application using ClickOnce. The problem is, I am saving user generated files in the application's working directory. Now when the user installs the next version of the application, his old files w开发者_如何学Cill no longer be available to him. What is the best workaround for this problem - or does this mean I have to roll my own installer!

thanks!

When Windows Vista came out and developers could no longer store data in Program Files, Microsoft recommended using LocalApplicationData. We store a lot of cached data there, under a folder with our application's name. I wrote a blog entry showing exactly how to do this if you're interested.
