i got an error with partial declaration of 'BitmapSource.main page'must not specify different base classes.
In my XAML, I have
x:Class="BitmapSource.MainPage", xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone", xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
Then in MainPage.g.i.cs there the error that highlight is public partial class MainPage Microsoft.Phone.Controls.PhoneApplicationPage
How to solve it?
