By replacing the whole csproj you are leaving out the important part for picking up the ResX files, so that is the reason why it doesn't work I would think.

Does the demo work if you don't replace the whole csproj? Does your project work if you include those references to the ResX files?

Thank you for your response and sorry for the confusion, I only replaced the PropertyGroup and did not touch the rest of the file.

Can repro this issue on the latest 17.10 preview2.

I have the same issue but then for Android. Windows seems to be working using .net 9 preview 4.
