You might run into this problem:

When you try to make an Open/SaveFileDialog on in a WPF program, you might see that the dialog is displayed with the old graphics:

*yuk*

This seems to be caused by a detection inconsistency somewhere inside the Microsoft.Win32.

To solve the problem you could manually add a Reference to System.Windows.Forms, and use the System.Windows.Forms.OpenFileDialog or the System.Windows.Forms.SaveFileDialog.

This will display the beautiful Open/SaveFileDialog on Vista 64-bit.

Good luck
