After you build the Windows Installer, you will see several directories in the project:

• WindowsApp - This is a staging directory where the application files are copied and where the uninstaller is copied to
• WindowsBuildInstall - This is a .NET solution for the installer
• WindowsBuildUninstall - This is a .NET solution for the uninstaller
• WindowsInstall - This is the compiled installer
• WindowsUninstall - This is the compiled uninstaller
