  • Once you add the application page it will automatically create the Layouts Folder.
  • In the solution explorer you could see Layouts -> CustomApplicationPage ->CustomApplicationPage.aspx.
  • Once you deploy the solution the pages will be automatically placed in the 14 hive layouts folder.
  • Open CustomApplicationPage.aspx from the solution explorer.
  • In the "PlaceHolderMain" add one asp label control.
  • And change the "PlaceHolderPageTitle" content to 'My Application Page" as shown in the following code.

    <%    @ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
    <%@ Import Namespace="Microsoft.SharePoint.ApplicationPages" %>
    <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
