How do I Enable ASP.net 3 or 3.5 ?

How do I enable ASP.net 3 or 3.5 Hosting? I only see ASP.NET 1 or 2 in my control panel.

ASP.net 3 and 3.5 are not true asp.net versions, they are just addons for asp.net 2.0.

So enabling ASP.net 2.0 in control panel will automatically include ASP.NET 3.0 and 3.5 features.
