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

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:

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.
Solution

  • 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.
