Salve,
sono alle prime armi con la programmazione ASP .NET. Sotto Windows 2003 Server, e usando Visual Studio 2003, non riesco ad aprire, da IIS, una pagina HelloWorld.aspx che contiene il codice seguente:
<%@ page language="C#" Debug="true" %>
<html>
<head>
<title></title>
</head>
<body>
<h1>Hello world!</h1>
</body>
</html>
in quanto viene aperto il browser Internet Explorer che visualizza una pagina il cui codice è (lo riporto non potendo inserire file allegati):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

Basta copiare il contenuto e salvarlo come file .htm per visualizzarlo correttamente. La directory virtuale esiste e contiene il file HelloWorld.aspx. Accedo come amministratore ed ho tutti i permessi sull'applicazione Helloworld che ho creato.
Non ci sono problemi se invece provo ad aprire una pagina html. Sembra quindi che non sia possibile eseguire il codice <%@ page language="C#" Debug="true" %> perchè da qualche parte non ne verrebbe consentita l'esecuzione...Spero di ricevere un aiuto util, saluti.
