publish failed with PublishSingleFile=true

[zhangchaoza]

Description

I created a app by using the default template and test if it can be packaged as a SingleFile by using PublishSingleFile=true. But i have trouble in publish command.

The command I used is dotnet publish -c release -p:WindowsPackageType=None --sc -f net7.0-windows10.0.19041.0 -p:PublishSingleFile=true MauiDemo.csproj

output:

MSBuild version 17.4.1+9a89d02ff for .NET

I believe this is a limitation of WinUI Packaged Applications.

• You're trying to use "PublishSingleFile" on a packaged application. That doesn't work since the point of it is to be a "Packaged" MSIX application that you install. As MAUI uses Published WinUI apps as its default deployment system, it also won't work.
• Unpackaged WinUI/MAUI apps are also, I believe, unsupported at the moment. You can see a task tracking that here (Windows Unpackaged support in .NET MAUI  #10564). Once this work is completed, you should be able to use PublishSingleFile for that.
