I made a WPF application (.net core 3.1) and then towards the end I wanted to change the icon, as usual I opened the properties>application and loaded my icon. But it doesn't change anything... remains the same default icon. The size of my icon is 256x256 and obviously has an .ico format. I tried to delete the folder where the executable is located and to build again, I also tried to run the application without debugging mode, but nothing. I noticed, however, that the main window when you change the Icon attribute updates the window icon. But nothing to do for the .exe file.
Does anyone know how to solve this problem?
P.S. I don't think it's the icon the problem because I tried to load another icon that I used in the past with another WPF application
