wpf - Simple dialog based application using C# -

i want develop simple windows application (using c#) follows:

• a simple dialog based application 3 screens
• the first screen screen welcome user , give explanations on how proceed
• the second 1 drop screen user can drop files on (image files)
• it performs operations on provided images , displays live results list view status , percentage of completion

i have image manipulation code , easy part me, i'm quite lost application itself...

here questions:

• should develop using winforms or wpf? i'd add own font, have transparency on images use , display custom listview cells , controls...
• what best way of having multiple screens in dialog based application? thinking of using tabcontrol, hide headers , programaticaly switch first screen second 1 once user has clicked on 'next' button, third screen once files have been dropped on window...
• and best way have background process performs operations on image files, giving user feedback (progress bars percents) without blocking ui

should develop using winforms or wfp? i'd add own font, have transparency on images use , display custom listview cells , controls

i vote wpf.

• it support more drag , drop operations
• it has better ui such round corner , maybe transparancy (haven't used transparancy)
• very easy custom listview , controls

what best way of having multiple screens in dialog based application

for having multiple screen, can use frame, , change different view using source. ok use tab controls, provide user skip page 2 , instead go directly page 3.

and best way have background process performs operations on image files

backgroundworker useful it. should thread safe.
