Aspnix.com is my preferable option for windows solutions. So far they have been excellent. I've had to contact support a few times and on all occasions my questions was answered very promptly.

As I know, Aspnix is great hosting provider too. But I use ASPHostPortal for my hosting. I dont want to switch as I'm very happy with them. If I have clients, I always use them. You just need to sigh up their Host One package, I think that's very enough. Good luck. :)

ASP.NET is a programming framework built on the common language runtime that can be used on Alentus web servers to build powerful Web applications. The first version of ASP.NET offered several important advantages over previous Web development models.
