I was wondering if there was a good way to monitor a document library on SharePoint for changes (new files added, files changed / checked-in, files deleted, etc.)
Basically, what System.IO.FileSystemWatcher does on local / network directories.
Are there events that get fired when documents are uploaded to document libraries?
Perhaps creating a workflow on the document library that fires onCreate / onModify would be better?
Any suggestions are welcome.
Take a look at event receivers for lists/document libraries. There are both synchronous and asynchronous options built into the object model. (ItemAdded, ItemAdding, ItemUpdated, ItemUpdating ... and so on.)
