From Lunarpages Web Hosting Wiki
Do you support ASP.NET on Lunarpages web hosting?
We sure do! ASP.NET comes with all of our Windows hosting plans. We have both 1.1.4322.0 and 2.0.50727.0 versions on the server. You are able to select between the two for each of your domain(s) in Plesk under ASP.NET, Change Version.
ASP.net 3.0 and 3.5 are only added extensions to the .net 2.0 Framework. Unfortunately Plesk will not show 3.0 or 3.5 as they are only added extensions to 2.0 and there is nothing that can be done to change the version showing in Plesk.
If you require ASP.net 4.0, please send an email to email@example.com with your primary domain name, your Windows username, and the last 4 digits of the credit card on file. If you do not remember the last four digits of the credit card on file, or pay by an alternate method, please include your full name and the full billing address as well as the daytime phone number currently listed on the account.
