I noticed that in XAML the Intellisence listbox is not updated or opened when I want extended options by pressing ".".
To reproduce: 1. Start new silverlight project (for example: Silverlight Application). 2. As content of the <Grid> </Grid> tags type "<Grid." as soon as you press "." the listbox should be updated with new options. Also when you press enter after the "." the listbox closes and won't open again.
Only when you type "<Grid" press enter and then type "." the new listbox opens.
