Hello,
I believe Metro Studio always create PNG files, even if you specify ICO as filetype when exporting.
Why?
I tried to use the ICO file in a MSI project (Setup Project in Visual Studio 2022 with the installer extension).
It never worked. (my MSI's add and remove icon was blank and on the desktop shortcut it was the default WPF app icon).
I used one of the "ICO converted" online then use the "converted" ICO file.
Now, I see the proper icon after installing my app using an MSI.
I hope you can take a look at it... because I spent 2 hours on this lol
Thanks,
Pascal
