We have added support for __autoload to VS.Php. Here is how it works.
When you have in your code something like this:
$a = new foo();
VS.Php will try to include foo.php. This is the default behavior. It is equivalent to this:
require_once("foo.php");
$a = new foo();
You can change the behavior of this feature by adding a registry key. We will put this in the UI at some point in the future.
Under the HKEY_LOCAL_MACHINE\Software\VS.Php\V2.3\2005 (Change your edition if different)
Add the following string entry autoloadTemplate
