No layers in the exported image of the MXD project using C#

Question

I have created a console application to export the active view of an MXD document using C# ArcObjects. The app works, but for some reason the exported image is missing all the layers in the map and legend. I checked, all layers are enabled, the problem is in the export implementation.
