Default Wpf NET 5 'single file' + 'trim' crashes on start

[LaraSQP]

Thought you might want to know.

The Wpf default app (here EtoNet5) runs fine without the trimming.

With trimming, the app crashes.

This is Eto.Forms 2.5.11

The publish profile FolderProfile.pubxml is as follows:

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <Configuration>Release</Configuration>
    <Platform>Any CPU</Platform>

    <PublishReadyToRun>False</PublishReadyToRun>
    <PublishTrimmed>True</PublishTrimmed>
  </PropertyGroup>
</Project>

The windows event log produces three items:

The publish build works as expected but for:

--warnaserror- --warnaserror ";NU1605"

Let me know if you want anything else.

By the way, the Linux Gkt project only produces the following in the Publish folder:

EtoNet5.Gtk
EtoNet5.pdb
EtoNet5.Gtk.pdb

Yes, this is a problem with WPF itself. It does not support trimming or single file in .NET 5. I have hopes that it'll work with .NET 6.

Closing the issue, then.
