title: File managment on Azure blob storage
body: <p>Is there a service or a(n open-source) library that could help in programmatically manage files stored on Azure blob storage. By manage I mean search with security trimming, authorizing download, document-versioning.</p>
  
  <p>I've looked online but most of the solutions are more of end-user solutions. Should I build my own layer to talk to blob storage or there's a way that can take a part of this burden off my shoulders?</p>
  
  <p>A solution that could work with both cloud (blob) and on-premise storage would be great!</p>
