That's too bad. I was hoping to overcome a limitation [bug?] in Visual
Studio 2008 on x64Vista - IntPtr is the wrong size because the web
server hauled around by Visual Studio is x86. It is causing my calls
into the native APIs to fail.

Agreed - a very bad description. Here's what I'm doing and seeing.

(1) Create a Web Application (taking defaults)
    - Default.aspx
    - Default.vb
(2) Press <F5> to build and run

Upon attempting to run, I receive the error, "could not connect to webserver".

(3) Project Options -> Run -> General
    - Check 'Run on external console'

No error. Console output is:

Adding applications '/:.'...
Registering application:
    Host:          any
    Port:          any
    Virtual path:  /
    Physical path: /home/jeffrey/Projects/Mono-Web-Test/Mono-Web-Test/
Listening on address:
Root directory: /home/jeffrey/Projects/Mono-Web-Test/Mono-Web-Test
Listening on port: 8080 (non-secure)

Unfortunately, no web server is listening:

$ netstat -a | grep 8080

Indeed, I timeout when attempting to connect to
using Firefox.
