2 questions: 1) Implement silverlight application which converts string "<color name>_<number>" (for example "red_1") to textbox properties: <color_name> - the color name of text <number> - if number % 2 == 0, set color A, otherwise set color B You have to use IValueConverter and data binding. 2) write function which takes valid directory path as argument and prints out 10 biggest files in path's sub tree. Use recursive algorithm. <- i din't have enough time to finish it. It must work without crashes and must show comprehensive error messages.
