title: Using an F# portable library with HTML5/Javascript on Windows 8 and Windows Phone 8
body: <p>sorry if this has already been answered but the other posts on this are out of date.</p>
  
  <p>I want to build a Windows 8 app in HTML5 and JavaScript that uses an F# portable library project to do the computational heavy lifting. Is this allowed? When I tried to add a reference to my F# project from the JS project VS2012 gave me an error but then let me add it anyway, will this blow up in my face later? I also want to make a Windows Phone 8 version</p>
  
  <p>Thanks</p>
