I have a Winform application and I would set two different icons, one for the application shown in the taskbar and the left-upper corner of the window and a different one for the ALT+TAB switch. The properties Icon of the Form sets only the small one but seems that it is used also for the ALT+TAB view. In Visual Studio 2012 I've already tried to select a diffenrent icon under Project Properties > Application > Resources > Icon and Manifest.
Any help will be appreciated!
