How do you write the url in the webbrowser?
When I developed Asp.Net pages in VS2008 I was irritated to say at least when I was unable to debug them at all. I just got an error page when I tried running the app. I had no idea how to make it work so I started looking all over the net for an answer. Then I found it.
Visa uses IPV6 addresses by default, so if you write
http://localhost/MyProject/Default.aspx
it will result in a error page saying that it cant find the page. Reason is that it changes the address to a IPV6 address that your browser wont accept.
If you change it to
http://127.0.0.1/MyProject/Default.aspx
it may work better. It is worth a try anyway.
I have had no trouble with this webserver running ASP.Net apps on Vista x64 since I found the thing above out.
Cheers
