將滑鼠游標移動到你想Debug的專案上，按右鍵選擇屬性 > 選擇Debug，你將會看到它。
If you want to debug your saving state mechanism, there is an useful setting "Tombstone upon deactivation while debugging".
Move mouse on the target project in solution explorer, and right-click, then select "Properties". In the "Debug" tab, you can find a check box for it. With the check box selected, your application will be tombstoned immediately after you press start button.
