when I run this C# code, no problems... but when I translate it into VB.NET it compiles but blows due to 'CompareString' member not being allowed in the expression... I feel like I'm missing something key here...

private void PrintButton_Click(object sender, EventArgs e)
{
if (ListsListBox.SelectedIndex > -1)
{
    //Context
    using (ClientOM.ClientContext ctx =
        new ClientOM.ClientContext(UrlTextBox.Text))
    {
        //Get selected list
        string listTitle = ListsListBox.SelectedItem.ToString();
        ClientOM.Web site = ctx.Web;
        ctx.Load(site,
            s => s.Lists.Where(l => l.Title == listTitle));
        ctx.ExecuteQuery();

        ClientOM.List list = site.Lists[0];

        //Get fields for this list
        ctx.Load(list,
            l => l.Fields.Where(f => f.Hidden == false 
      && (f.CanBeDeleted == true || f.InternalName == "Title")));
        ctx.ExecuteQuery();

        //Get items for the list
     ClientOM.ListItemCollection listItems = list.GetItems(
      ClientOM.CamlQuery.CreateAllItemsQuery());
        ctx.Load(listItems);
        ctx.ExecuteQuery();

        // DOCUMENT CREATION CODE GOES HERE

    }

    MessageBox.Show("Document Created!");
}

}

but in VB.NET code this errors due to not being allowed 'CompareString' members in the ctx.Load() methods...

Private Sub PrintButton_Click(sender As Object, e As EventArgs)
    If ListsListBox.SelectedIndex > -1 Then
        'Context
        Using ctx As New ClientOM.ClientContext(UrlTextBox.Text)
            'Get selected list
            Dim listTitle As String = ListsListBox.SelectedItem.ToString()
            Dim site As ClientOM.Web = ctx.Web
            ctx.Load(site, Function(s) s.Lists.Where(Function(l) l.Title = listTitle))
            ctx.ExecuteQuery()

            Dim list As ClientOM.List = site.Lists(0)

            'Get fields for this list
            ctx.Load(list, Function(l) l.Fields.Where(Function(f) f.Hidden = False AndAlso (f.CanBeDeleted = True OrElse f.InternalName = "Title")))
            ctx.ExecuteQuery()

            'Get items for the list
            Dim listItems As ClientOM.ListItemCollection = list.GetItems(ClientOM.CamlQuery.CreateAllItemsQuery())
            ctx.Load(listItems)

            ' DOCUMENT CREATION CODE GOES HERE

            ctx.ExecuteQuery()
        End Using

        MessageBox.Show("Document Created!")
    End If
End Sub
