Miembro obsoleto

El antiguo CreateRenderWindow está marcado como Obsoleto, para portar el código antiguo a este método, corrige tu código anterior como el siguiente fragmento de código:

  //Renderer renderer = ... your renderer instance

//RenderParameters renderParameters = ... your render parameters

//Control control = ... your control for rendering.

//renderer.RenderFactory.CreateRenderWindow(renderParameters, control.Handle);

//The above code should be fixed like the following line, pass a Win32 handle.

renderer.RenderFactory.CreateRenderWindow(renderParameters, WindowHandle.FromWin32(control.Handle));
