Ok this is not enough, it was a coincidence I guess.

The workaround was :

publish the first project as self contained single file x64

rename the \obj\Release\net5.0-windows\apphost.exe to singlefilehost.exe

publish the other project as self contained single file x64

compile my Inno Setup Script, picking the files in the respective \bin\Release\net5.0-windows\publish\ folder

Good answer!!
