title: Submitting form including file upload to ASP.NET webform from HTML or MVC view
body: <p>there is a ASP.NET webform app in use and I should upgrade most of it to MVC (specifically Umbraco 7 CMS that is MVC-based).</p>
  
  <p>Since most of the business logic is written in webforms, my question is - can I somehow collect data - and most important, input file data - in HTML form (or MVC view to be exact) and submit it to the existing webform?</p>
  
  <p>Those webforms have their own web controls and round trips, dealing with submission on postback, in a classic way. I guess I could rewrite most of the code to accept Request.Form without postback (CORS is not the issue since it's hosted on the same server)...</p>
  
  <p>But how to manage the file upload since webforms use FileUpload web control?</p>
  
  <p>(One webform is written in C# and the other in Visual Basic, but I guess I will manage to "translate" it once I get the solution...)</p>
  
  <p>Thanks in advance</p>
