Hi,

Thank you for your
```
I Replaced public virtual Person Person { get; set; }

```
with

```
public virtual ObservableCollection<Person> Persons { get; set; }
```

but not work And Exception:

```
The expression 't => t.Personss.get_Item(0)' is not a valid property expression. The expression should represent a property: C#: 't => t.MyProperty' VB.Net: 'Function(t) t.MyProperty'.
```
