Application.Idle event not firing in WPF application

Question

I am using a third-party Windows Forms control that performs some actions \"delayed\" using the Application.Idle event.

Now that we\'re moving our application to WPF

Answer 1

If you are using a WPF Application, you are actually no longer using the System.Windows.Forms.Application class to run your application, even if your application contains a Windows Forms Control.

Instead, you are using the System.Windows.Application class (different namespace).

Answer 2

You should read this page on MSDN which describes the message loop behavior in a WPF application. In particular it looks like the ComponentDispatcher class can be used to catch a ThreadIdle event which would roughly correspond to the Windows Forms Application.Idle event.

You could then presumably use the System.Windows.Forms.Application.RaiseIdle method to raise the Idle event as the component expects.
