"Xamlviewer" folder is deleted after installing .Net Framework 3.5 SP1 on a Windows XP / Windows 2003 system.

When you install .Net Framework 3.5 SP1 on a Win XP / Win 2003 system, it deletes a folder called "Xamlviewer" located in C:\WINDOWS\Microsoft.NET\Framework\v3.0\WPF. The "Xamlviewer" folder contains three xaml files. The XamlViewer files were removed in NetFx 3.5 SP1 because they are no longer needed to view XAML files. (There are stub files in Windows Vista/Windows 2008 due to manifest requirements.) The framework now handles XAML-viewing internally, so there should be no loss of functionality with this change. It should not happen on vista or higher OS. Those 3 files are removed in between 3.0 sp1 and 3.0 sp2 on down-level OS's. These no longer are a part of .net 3.0 in sp2 on down-level OS, and since sp2 is a major upgrade, it will uninstall 3.0 sp1, and those files should go away.
