New Post: Files in InstallDir

Hi,

I have a project where I am setting the InstallDir property using a ManagedAction.
This is working fine.
But how do I add files to the InstallDir folder?
This should be easy, but I haven't managed to get it right:

var msiProject = new Project("My App",
                new Dir(@"[INSTALLDIR]",
                new File(@"ClientFiles\MyClient.exe")));
msiProject.Actions.Add(new ManagedAction("SetInstalldir",
                        Return.check,
                        When.Before,
                        Step.InstallFiles,
                        Condition.Always));

Best regards
Flemming
