Designer should offer namespace suggestions when pressing CTRL+. (period) just like WPF.

Is your feature request related to a problem? Please describe.
Whenever I am referencing a newly-created Avalonia control in another, I must remember the rather-complex xmlns syntax. I've never memorized this by heart because usually this can be automatically through a hotkey shortcut in WPF.

It breaks flow to have to look up how to do this, and it's not something that I remember for long because when I go back to working in WPF, I never have to do it.

Describe the solution you'd like
I would like to be able to press CTRL + . (that's the period key) and have an option to add the appropriate xmlnx to my current control/window, as is done in WPF.

When using WPF, referencing a control which is not properly qualified will show an underline and a light bulb:

Pressing CTRL+. or clicking on the lightbulb shows the options for resolving the problem,

Describe alternatives you've considered
As mentioned above, the absence of this feature requires remembering the proper syntax for qualifying the type which I find difficult to remember and easy to write incorrectly.

Additional context
I tried this in Visual Studio 2022. I have not tried in Visual Studio 2019.
