The command-line compiler takes an feed URL or the file name of an existing feed and generates a class file in either VB.Net or C#. The command line is quite simple: As a walkthrough, here's the process of using RssDl.exe to cosume YouTube's top favorites feed:
    [XmlElement("player", Namespace="http://search.yahoo.com/mrss/")]
    public YoutubePlayer Player {
        get {
            return _player;
        }
        set {
            _player = value;
        }
    }
    
    [XmlElement("thumbnail", Namespace="http://search.yahoo.com/mrss/")]
    public YoutubeThumbnail Thumbnail {
        get {
            return _thumbnail;
        }
        set {
            _thumbnail = value;
        }
    }
    
    [XmlElement("category", Namespace="http://search.yahoo.com/mrss/")]
    public YoutubeCategory Category {
        get {
            return _category;
        }
        set {
            _category = value;
        }
    }
    
    [XmlElement("credit", Namespace="http://search.yahoo.com/mrss/")]
    public string Credit {
        get {
            return _credit;
        }
        set {
            _credit = value;
        }
    }

    <script language="c#" runat="server">
        void Page_Load(object sender, EventArgs e)
        {
            YouTubeRss rss = YouTubeRss.Load();
            DataList1.DataSource = rss.Channel.Items;
            DataList1.DataBind();
        }
    </script>
</head>
<body>
    You Tube Top Favories(Media Rss)
    <form id="form1" runat="server">
        <asp:DataList ID="DataList1" runat="server" RepeatColumns="3" GridLines="both">
            <ItemTemplate>
                <asp:Image ID="Image1" runat="Server" ImageUrl='<%# Eval("Thumbnail.Url")  %>' /><br />
                 <asp:HyperLink ID="HyperLink1" NavigateUrl='<%# Eval("Player.Url") %>' Text='Link' runat="server" />
            </ItemTemplate>
        </asp:DataList>
    </form>
</body>
</html>

Note that you can automate the process of executing the RssDl.exe compiler by placing it in a Build Events / Pre-build event command line to insure that the generated source file matched the current feed. Of course this could lead to compilation errors, but that's the whole point of doing strong-typed classes. PreBuildEvent.png
