You are creating an ASP.NET application by using the .NET Framework 3.5.

The application will reference a third-party component. The component might throw an unhandled exception from a background thread, causing the ASP.NET worker process to be terminated.

You need to ensure that any unhandled exceptions are logged before the application terminates.

What should you do?

A.
Handle the AppDomain.CurrentDomain.UnhandledException event.

B.
Add a try/catch block to the Page_Load method.

C.
Configure the application to use a custom error page.

D.
Handle the Application_Error event.
