Some ASP.NET methods should have predefined names that can't be changed.
For example,
Global.asax
public class Global : HttpApplication
protected void Application_Start(object sender, EventArgs e)
protected void Session_Start(object sender, EventArgs e)
protected void Application_BeginRequest(object sender, EventArgs e)
protected void Application_Error(object sender, EventArgs e)
...
MyPage.aspx
public partial class MyPage : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
...
I think StyleCop+ should definitely provide some abilities to handle it.
