i work a project with visual studio 2022 and i use gifs.
i save the canvas and use method XamlWriter
but when i load canvas, i give an error

"System.Windows.Markup.XamlParseException: "Unable to set unknown member '{http://wpfanimatedgif.codeplex.com}ImageBehavior.AnimatedSource'." Line number '1' and line position '737'.'"

My Code is:

//save
loadedEventrunned = false; 
FileStream fs = File.Open(projectpath, FileMode.Create);
XamlWriter.Save(canvasmain, fs);
fs.Close();


//load
loadedEventrunned = true;
FileStream fs = File.Open(projectpath, FileMode.Open, FileAccess.Read);
savedCanvas = XamlReader.Load(fs) as Canvas; //error at here
fs.Close();
sp.Children.Add(savedCanvas);
savedCanvas.PreviewMouseUp += canvasmain_PreviewMouseUp;
savedCanvas.PreviewMouseMove += canvasmain_PreviewMouseMove;

How do i fix it??
