ImageSource for Icon property must be an icon file - Embedded Resource

Question

I need to assign an Icon to a WPF window, but cannot seem to do this from a resource file. I tried this solution, but end up with:

ImageSource for Icon property must be an icon file

But, if I try to leave it as Icon, then I get an error that I need to convert to ImageSource...

Icon = Properties.Resources.myIcon.ToImageSource();

Answer 1

I ended up doing the following:

using (var iconStream = new MemoryStream())
{
    icon.Save(iconStream);
    iconStream.Seek(0, SeekOrigin.Begin);
    return BitmapFrame.Create(iconStream);
}

which was actually one of the unaccepted answers from the same question I already referenced: just a different response
