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。但是会弹出以下消息：
这是错误消息文件中提到的内容：

===================
问题是..我做错了什么和/或如何解决这个问题？
重要的提示：
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.
