I am trying to develop web parts in VS 2008/WinXP
I created a Web Site project, and added a couple of web parts within the default form in default.aspx
<form id="form1" runat="server">
<div>
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<asp:WebPartZone ID="WebPartZone1" runat="server">
</asp:WebPartZone>
</div>
</form>
When I first ran it (in the debugger), a popup told to me enable Windows authentication in IIS (so something is working!). I enabled the Windows authentication, and now when I run it I get a blank screen. Same result if I open it in IE via the url (rather than debugger).
Following is the the source view.
