Custom aspx pages in SharePoint 2010

While migrating Custom aspx pages from MOSS 2007 to SP 2010, below mentioned pages directives are to be modified accordingly.

MOSS way of doing

<%@ Page Language="C#" Inherits="Microsoft.SharePoint.ApplicationPages.NewListPage" MasterPageFile="~/_layouts/application_Custom.master" %>

SP 2010 way of declaring the directive,

<%@ Page language="C#"
 MasterPageFile="~/_layouts/application_Custom.master"
 Inherits="Microsoft.SharePoint.WebPartPages.WebPartPage,Microsoft.SharePoint,Version=14.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c"%>

If the page inherits publishing layouts page, the directive should be modified as shown below,

MOSS way of doing:

<%@ Page Language="C#" DynamicMasterPageFile="~masterurl/default.master" Inherits="Microsoft.SharePoint.Publishing.Internal.CodeBehind.CategoriesPage"%>

SP 2010 way of doing: 

Follow the below two steps to apply master page here. MasterPageFile tag is not supported directly.

1. <%@ Page Language="C#" Inherits="Microsoft.SharePoint.Publishing.PublishingLayoutPage,Microsoft.SharePoint,Version=14.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c"%> 

2. And, then under script tag, override "OnPreInit" method & assign master page there.

protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
this.MasterPageFile = "SomeOther.master";
}
