.SYNOPSIS
Publish the app and mirror the output to an FTP-deployed IIS site.
.DESCRIPTION
- Builds with dotnet publish.
- Drops app_offline.htm to pause the IIS site while files upload.
- Uses WinSCP (ftp) to mirror publish output into $RemoteDir (deletes extraneous remote files).
- Removes app_offline.htm when done.
.PREREQS
- WinSCP.com available in PATH or pass -WinScpPath "C:\Path\To\WinSCP.com".
- FTP user must have write/delete rights to $RemoteDir.
- If you have RDP, you can still run this locally; the app_offline flag safely stops the app without touching the pool.
.EXAMPLE
pwsh ./scripts/deploy-ftp.ps1 `
-FtpHost "ftp.example.com" `
-FtpUser "deploy" `
-FtpPassword (Get-Content ./secrets/ftp.pwd -Raw) `
-RemoteDir "/httpdocs" `
-Configuration Release
