You need to add a reference to "Microsoft Shell Controls and Automation".

This will add a link

Type shellAppType = Type.GetTypeFromProgID("Shell.Application");
Object shell = Activator.CreateInstance(shellAppType);
Shell32.Folder2 f = (Shell32.Folder2)shellAppType.InvokeMember("NameSpace", System.Reflection.BindingFlags.InvokeMethod, null, shell, new object[] { "C:\\temp" });
f.Self.InvokeVerb("pintohome");

This will remove a link by name

Type shellAppType = Type.GetTypeFromProgID("Shell.Application");
Object shell = Activator.CreateInstance(shellAppType);
Shell32.Folder2 f2 = (Shell32.Folder2)shellAppType.InvokeMember("NameSpace", System.Reflection.BindingFlags.InvokeMethod, null, shell, new object[] { "shell:::{679f85cb-0220-4080-b29b-5540cc05aab6}" });
Console.WriteLine("item count: " + f2.Items().Count);
foreach (FolderItem fi in f2.Items())
{
Console.WriteLine(fi.Name);
if (fi.Name == "temp")
{
((FolderItem)fi).InvokeVerb("unpinfromhome");
}
}

thanks
