# AppHostModule The purpose of the AppHostingModule is to be able to host external applications directly on the edge device. The capabilities are: * Hosting of one or more applications (only .net supported currently) * Handles application lifecycle, by starting, stopping and monitoring applications * Download application versions from blob storage (cloud) * Perform sha256 checksum validatation of downloaded content, to ensure integrity * Relays logs from the applications (for cloud upload) NB: When updating an application to a new version, it is necessary to run the direct command "DownloadApplication" to trigger the download and activate the new application version. It does not happen automatically. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
