WPF publish adds Windows Forms dlls (including design time dlls)

[myblindy]

Describe the bug

As the title is, a plain WPF application seems to somehow publish the Windows Forms dlls, including the design time ones, which are both very large and (presumably) not necessary.

To Reproduce

1. Clone https://github.com/myblindy/wpf-publish-issue and open the solution
2. Create a basic self-contained publish to folder profile, mine was Windows-x64. Like this:
   
3. Publish to the folder
4. Notice the WF dlls in the publish folder:
   

Exceptions (if any)

• The IDE (VS / VS Code/ VS4Mac) you're running on, and its version

Visual Studio 2022 Version 17.2.0 Preview 4.0, but this has been an issue for a long while, on both .Net 6 and 7 (haven't tried before that).

Removing the websdk tag since this is not related to web or the Visual Studio publish. The same can be reproduced with dotnet publish.

Adding @LakshanF to see if this is something you can help with.

Removing the websdk tag

Yeah, I was a bit surprised at that auto tag as well.

Moving to WPF as I assume they control which files get published during the build.

FWIW, I’ve been running into this issue for a long time now coming from the other direction (pure Windows Forms app, still deploys completely unused WPF runtime libraries). I think it has something to do with runtime packs. Hope this helps!
