I am copying the code in this discussion: Change desktop wallpaper using code in .NET

But now I have a problem with the System.Drawing reference. At the line:

System.Drawing.Image img = System.Drawing.Image.FromStream(s);

I have the following error: the type name 'Image' could not be found in the namespace "System.Drawing".

I right-clicked on project "CambioSfondo" -> Add -> Project Reference -> COM -> searched for System.Drawing.dll and add it, but the error is still there.

Could someone please help me? Look my error

Try System.Drawing.dll exists in Reference -> Assemblies -> Framework. – MrMoeinM Jul 10 '21 at 09:35

What project type did you create? – TaW Jul 10 '21 at 09:36
Output Type: Console Application Target framework: .NET 5.0 – Albanese98 Jul 10 '21 at 10:11

Target .NETFramework instead. – Hans Passant Jul 10 '21 at 10:16

GDI+ is known for it's slowness and limited capabilities. Unless you're going to work with Windows Forms you shouldn't use System.Drawing. Use alternatives, e.g. SkiaSharp – JL0PD Jul 10 '21 at 11:39
