Hi Dennis,

I reproduced this exception when I tried to close the application form.

If you also met that when you try to close application, I think that’s because your code hadn’t call close for this layer.

Generally you can close it after use it like this:

```
    map.CurrentExtent = fileGeoDatabaseFeatureLayer.GetBoundingBox();
    fileGeoDatabaseFeatureLayer.Close();
    map.Refresh();

```

Regards,

Ethan
