Filterable collection mvvm

Does it any good implementation of Filterable Collection for C#?

What is required:

var data = GetEmployees();

_filtered = new FilterableCollection<Employee>(data);
_filtered.SetFilterExpression(empl => empl.DepartmentId == SelectedDepartment.Id);

...

set
{
  SelectedDepartment = value;
  _filtered.UpdateRepresentation();
}

Paging, CustomFilterBuilder and Virtualization would be a plus but not required at the moment.

I'm not sure why you need this... WPF already does supports this, via the ICollectionView interface.

ICollectionView view = CollectionViewSource.GetDefaultView(data);
view.Filter = o => ((Employee)o).DepartmentId == SelectedDepartment.Id;
