Win 10 -> VS 2019 -> .NET Core 3 WPF application -> Publish to directory (self-contained for linux-x64) -> Publish failed

Question

Weird issue I've faced today.

Pre-requisites: Installed:

VS2019
.NET Core 3.0

Steps to reproduce the issue:

Create new "WPF App (.NET Core)"
To the MainWindow.xaml add single TextBlock:
    <TextBlock Text="WPF on Linux" TextWrapping="Wrap"/>
Create new Publish Profile like the following:

Then save and publish

Expected to see the application being published. But instead the following message pops up:

And here is the content of the mentioned in the error message file:

2019-10-28 19:39:43
System.AggregateException: One or more errors occurred. ---> System.Exception: Publishing failed.

---> (Inner Exception #0) System.Exception: Publishing failed.<---

System.Exception: Publishing failed.

===================

The question is.. What am I doing wrong and/or how to fix the issue?

Important note:

If Deployment Mode is set to "Framework Dependent", and the Target Runtime is "linux-x64" then the project is published into the directory with no issues.
If Deployment Mode is set to "Self-contained", but Target Runtime is "win-x64", then deployment works with no issues.

The error is in the build output window:

There was no runtime pack for Microsoft.WindowsDesktop.App.WPF available for the specified RuntimeIdentifier 'linux-x64'

WPF is not supported on Linux, only Windows.

Do you know if there is some intention to make it work also on linux ? (Like git issue, etc...) – TarmoPikaro Oct 23 '21 at 08:39

@TarmoPikaro MAUI is one option for cross platform .NET apps, but for some reason Microsoft is leaving the Linux support up to the community. There is also Uni and Avalonia. I have used Avalonia to write desktops apps for Linux and it is good. – geometrikal Oct 24 '21 at 13:50
