I just upgraded from Visual Studio .NET 2003 to Visual Studio .NET 2005.
There are several questions I have about the code differences between them
(I use VB.NET for as my language of choice):

1. 2003 used "Public Class classname" and 2005 uses "Partial Class
classname". What, if any, difference is there between these?

2. The following things are included in the #Region " Web Form Designer
Generated Code " part of 2003's code, and are not included automatically in
2005:

   <System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()
   End Sub

   Control declarations, such as:
   Protected WithEvents lblWebsite As System.Web.UI.WebControls.Label

   Private designerPlaceholderDeclaration As System.Object

   Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
       InitializeComponent()
   End Sub

   Do I need to include any of these manually or anything else that serves
their purpose?

3. In 2003 the Page Events use clauses such as Handles MyBase.Load while
2005 uses Handles Me.Load. I am assuming that these will work the same?

I am sure that I will run into the other differences between the two, but
these are some of the important ones for me right now. Thanks.
