how to dotnet publish multiple exe-projects together in one single folder with different target-runtimes?

[LukasGelke]

we want to deploy two applications in tandem (one is used kinda as a "fire and forget" or "throwaway" process).
I've made a new empty project which references both, in order to have all DLLs on the highest version, regardless of which of those two applications brought it (mostly to deal with transient dependencies). We'd wanted to reduce deployment size with this, since Deps are mostly identical/subset.

This works at first glance.
However we've noticed one major issue. We have deps like this:

PublishProject -> App1 [net8.0-windows console] -> Lib1 -> {PackageReference N="System.Diagnostics.PerformanceCounter" V="8.0.0"}
PublishProject -> App2 [net8.0-windows WinForms] -> Lib1 ...

When using dotnet publish {PublishProject} it determines that "C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App\8.0.16\System.Diagnostics.PerformanceCounter.dll" is newer, and therefore ignores the NuGet.

However at runtime, App1 crashes because it is not using the WindowsDesktop-Runtime. And we don't necessarily want to "upgrade" that for App1, as it may run in a headless scenario

System.IO.FileNotFoundException: Could not load file or assembly 'System.Diagnostics.PerformanceCounter, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.
File name: 'System.Diagnostics.PerformanceCounter, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

Manually adding the "Microsoft.WindowsDesktop.App"-TargetFramwork entry to the App1.runtimeconfig.json lets App1 run again as expected (which tells me that this is indeed the problem)
