My Windows Phone application crashes when creating a new instance of binded list
BindedList Change:
OsyId = Response.recordedBills.Count > 50 ? new List<RecordedBillDetailViewModel>(Response.recordedBills.Take(50)) : new List<RecordedBillDetailViewModel>(Response.recordedBills);
MultiSelector:
<toolkit:LongListMultiSelector ItemsSource="{Binding OsyId}" x:FieldModifier="public" x:Name="longList" EnforceIsSelectionEnabled="{Binding EnforceSelectionEnable}" Margin="0,0,10,0" SelectionChanged="LongListMultiSelector_SelectionChanged" IsSelectionEnabledChanged="LongListMultiSelector_IsSelectionEnabledChanged" MaxHeight="600" Grid.Row="1" HorizontalContentAlignment="Stretch">
Crash Report:
{System.ArgumentException: Value does not fall within the expected range.

How can I solve it?
Instead of creating a new instance try to clear and add items to the list. It might help solve the problem. This is assuming OsyId is a ObservableCollection<RecordedBillDetailViewModel>
var itemsToAdd = Response.recordedBills.Take(50); // Take 50 is fine even when the response does not have 50 items. Need not add a contion for it.
OsyId.Clear();
foreach(var item in itemsToAdd)
OsyId.Add(item)
