After I recreated and rebuilt an app based on my old app, I have this error that did not happen in my old app.
The problem on stringFormatConverter
Error message:
The name stringFormatConverter does not exist in the namespace MobileSalesSystem
-- here my page:

using System.Threading.Tasks;
using Windows.UI.Xaml.Data;
namespace MobileSalesSystem
{
class stringFormatConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
DateTime dt = (DateTime)value;
string arg = dt.ToString("d");
return arg;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
return value;
}
}
}
