Does System.Windows.Forms.Timer send WM_TIMER message?

Does System.Windows.Forms.Timer send WM_TIMER message ?

Basically I want to set a timer that should generate 

WM_TIMER

message for every 5 seconds. I am using 

System.Windows.Forms.Timer

and the 

Tick

event is handled. But I am not getting WM_TIMER message in my WndProc().

Yes, WM_TIMER is what makes a Winforms Timer tick. Unobserved in your code however, it creates its own window, it doesn't use yours. It is an invisible one, the underlying .NET class is TimerNativeWindow, a private class of the Timer class. You can't ever override its WndProc(). Technically you could subclass it with NativeWindow after digging out the handle with Reflection, but that way lies dragons and should never be necessary.
