title: Help me understand Sharepoint
body: <p>We've been asked to create a web application. One part of the specification is that in future, it can be integrated into Sharepoint. The last version of this app was written in PHP and "integrated" by means of an iframe embedded into Sharepoint; not ideal.</p>
  
  <p>I'm looking to understand the use of Sharepoint in this context. I believe that you can write Sharepoint Applications which are more "native" to Sharepoint than the rough-and-ready iframe approach I discussed before. How easy is it to take a standard ASP.NET MVC application and fully integrate it into Sharepoint? </p>
  
  <p>Does anyone have any thoughts, experiences, or resources on this matter?</p>
