title: Windows CopyFilesDialog multiple files, no folder
body: <p>In my WPF app, I want to copy files using Copy Files Dialog builded in windows. I have found I can do it by: Microsoft.VisualBasic.FileIO.FileSystem.CopyFile, but the problem is I don't know how to copy many files using this dialog. The same as windows provides. You may select SOME files from a folder, copy them, and one Copy Files Dialog is shown. How can I achieve it - copying many files with ONE dialog, one after another?</p>
