  1. Your sample doesn’t work with non-english system locale settings. Just try to change Decimal symbol to comma for example (russian format: decimal symbol is comma, digit grouping symbol is space).

  2. Just change
    decimal total = (from l in li select Decimal.Parse(l.Total)).Sum();

    to
    decimal total = (from l in li select Decimal.Parse(l.Total, System.Globalization.CultureInfo.InvariantCulture)).Sum();

    in Page.xaml.cs

  3. GJ,
    I did not do vb in sometime. I will give it a shot, but might take some time, did you try c# to vb converters(this might be faster)
