Win 10 -> VS 2019 -> .NET Core 3 WPF 应用程序 -> 发布到目录（linux-x64 自包含） -> 发布失败

Question

我今天遇到的奇怪问题。

先决条件：已安装：

VS2019
.NET Core 3.0

重现问题的步骤：

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

预计会看到正在发布的应用程序。但会弹出以下消息：

这里是错误消息文件中提到的内容：

2019-10-28 19:39:43

System.Exception: Publishing failed.

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

问题是..我做错了什么and/or如何解决这个问题？

重要提示：

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.

错误在构建输出中 window:

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

Linux 不支持 WPF，仅 Windows。

Win 10 -> VS 2019 -> .NET Core 3 WPF 应用程序 -> 发布到目录（linux-x64 自包含） -> 发布失败

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

linux

wpf

deployment

.net-core-3.0

self-contained
