title: What is a good framework for filemanagment combined with ASP.NET MVC
body: <p>Here is the scenario:</p>
  
  <p>A user visits the site ask the latest version of only one document. he or she changes something to that document (locally), the format is word, and then re-uploads that document to the website.</p>
  
  <p>The uploading and downloading part is not that hard, but is there a framework that can for example analyse the differences from 2 documents (the one on the server vs. the one changed) and gives the user an option to merge (in case 2 people change the document and re-upload in different order)?</p>
  
  <p>My first thought it would become a something that looks like dropbox or a subversion repository? is there a framework for this that you can use for an ASP.NET MVC website?</p>
