I wanted to have another page (not default.aspx) in DotNetNuke based application. I found that there is no common code to generate CSS links. Actually, core code to create CSS links is duplicated in a few places. I've created a common class, that can be used in my custom page, as well as from Default.aspx and Components\Skins\Skin.vb . The class is posted in comment to the isssue.
