Question

I’m planning to deploy my DB file in the Users\CurrentUserName\AppData folder, because default User Account Control settings restrict write access to the Program Files directory where my program is installed.
First question – is this correct?

So far, I’ve created a custom folder, set the DefaultLocation property to [LocalAppDataFolder][ProductName], and put the .sdf file in that folder.
This works in Windows 7, but it doesn’t seem to work in Windows XP – I can’t find any sign of it being deployed anywhere.

So where and how should I deploy the DB file?

I’m also unsure how to set the connection string to the [LocalAppDataFolder] location – any suggestions?

Edit: The application is a WinForms application which will be downloaded from a website and installed using the installer created with Setup Project.

This works for me:

string fileName = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "SqlCe35AddinStore.sdf");

string connString = string.Format("Data Source={0};", fileName);
