Scenario: How to apply the SharePoint site's default master page on an application page (page in _layouts folder)

protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
//This is where you set the master page to be used by this application page.

this.MasterPageFile = SPContext.Current.Web.MasterUrl;
