Difference between @"pack://application:,,,[...] and IO.Directory.GetCurrentDirectory()?

I've noticed that when I add a line of <Window.Background></Window.Background> in the XAML file or in the C# code this.Background = new ImageBrush(new BitmapImage(new uri([...])); if I put in the "Uri" this: new Uri(@"pack://application:,,,/Myapp;component/image.jpg") I get an error when I try to compile it which says: "Could not locate resource "image.jpg" "

But if I change this to new Uri(System.IO.Directory.GetCurrentDirectory()+"\\image.jpg"); it never gives me an error. Why???? What is the difference between both methods? I am very comfortable with Directory but why the compiler doesn't show an error "Locating" the resource with IO.Directory? What's the difference?

The questions may sound too noob, but I don't understand why it gives an error in @"pack://application[...] and not with GetCurrentDirectory()

A pack:// Uri, will search embedded resources for the image. The resources are inside the DLL/EXE, rather than deployed to the same folder. To use an image as a WPF Resource you need to set the Build Action on the image to Resource.

Using the Directory approach simply searches the physical file system for the image.

More info here on WPF Pack Uri's.
