Some files remain when uninstalled

Question

When my project is uninstalled the following files remain

project folder
Project.exe
Project.exe.config

None of these are set to permanent.

I would like to ensure that all files and folders are removed on uninstall

Both for the user and for myself for further testing

as it stands right now if i make code changes i have to go in and manually delete these things

if you do not then when installed again it will use the old .exe files instead of the new updated one

Thanks
