Licensing

Localhost is friction-free

The bundled license note says you do not need a license file for `localhost`, `127.0.0.1`, or `::1`. For staging or production, place `ajaxuploader5.lic` in the application root, `bin`, `licenses`, or `App_Data`.

Need the full license instructions? Open `docs/02-License-Installation.txt`.

Deployment note

Before you move beyond local testing

Make sure the handler entry exists, `maxRequestLength` and `maxAllowedContentLength` fit your file sizes, and the temp upload folder is writable by the application pool identity.

ASP.NET Core?

Use CoreUpload for Core projects

The local AjaxUploader quick-start notes explicitly redirect ASP.NET Core applications to CoreUpload instead of the Web Forms control.
