I recently inherited an application from a developer who is no longer with the company. This application restores SharePoint sites from backups and extracts metadata and files from lists in the site. The application runs on a SharePoint server and uses the Microsoft.SharePoint assemblies in C# and VB.Net.
The backups come to us from various outside companies, and some of them have custom features installed. SharePoint Health Analyzer shows a warning about "Missing server side dependencies". When I look at the report there is a lot of "[MissingFeature] Database [db name] has reference(s) to a missing feature..." etc. The previous developer was supposed to implement a check for missing features, but it is obviously not working.
How can I identify features that the restored site references, but are not installed on the farm?
Thanks!
