1. Diffrence between win forms and wpf and wpf is better
2. new wpf window
3. make it default window
4. you showed some buttons and their diffrence
5. the diff between streamwriter and writeline and stringbuilder in next lesson
6.switch casee break
7. garbage collector to clean ram
8. 64x cpu

Thank you a lot for your effort professor specially after these 2 crashes
