Can you please explain me following doubts regarding application assistance and model class concepts related with BSP and WDA.
1> What is the need for seprate model class in BSP mvc when we have application class with us.
2>What is the difference between assistance class in WDA and application class in BSP. and if no then why in WDA we use assistance class by as MODEL class for component.(where as the same thing application class does in bsp but then we dont call it as model class for bsp)
