System.Windows.Forms.Timer uses the underlying windowing system. On Windows
the windowing system is available anyway (for ASP.NET as well). But on Linux
it is requires you to load an X-Server.

Use System.Threading.Timer or System.Timers.Timer to get a timer

It may be illogical but when I use System.Windows.Forms.Timer:Start in an
ASP.Net page it causes an exception with Linux/Mono (detailed message
Server error in '/c' application
Description: Error processing request.

Error Message: HTTP 500.

Stack Trace:

System.TypeInitializationException: An exception was thrown by the type
initializer for System.Windows.Forms.XplatUI --->
System.ArgumentNullException: Could not open display (X-Server required.
Check you DISPLAY environment variable)

The only reason why I send this for discussion is it works with
Windows/.Net. Test VS.Net project is attached.
