Trim in .net 6 breaks self contained single file publish mode

See original GitHub issue

Describe the bug References required for file dialogs will break. There’s an exception when trying to use them.

To Reproduce Steps to reproduce the behavior:

Run an avalonia app with a folder dialog
publish it with .net 6 with trim enabled
see the exception

Desktop (please complete the following information):

OS: Windows
Version 0.10.8

Additional context Work around, add these settings into your project file

<TrimMode>copyused</TrimMode>
<BuiltInComInteropSupport>true</BuiltInComInteropSupport>

this will prevent the needed files from being trimmed, and prevent com from being disabled which is needed.

I use the latest version (0.10.10). Actually, this problem occurs with OpenFileDialog as well. In Linux (Debian), IL trimming doesn’t break open folder/file dialog.
