ASP MVC4 Web API file upload: Unexpected end of MIME

So I’ve had a problem uploading a file using an HTML5 input of type file field.

For love nor money could I see a problem with the code above (in my defence I’m working on this project late in the evening and have my first dose of Man Flu this year, I’m a 2012 survivor see: www.manfluanonymous.com)

When I get into my server code an exception was getting thrown when I read the multipart post.

All the Googling in the world didn’t help me, I saw lots of people adding “\r\n” which I’m still scratching my head over to be honest, I saw others complain about the MVC4 beta...

But hang on: I’ve done this before: So what has changed? Actually something really silly,

I simply forgot to set the input name attribute!!!

Hope this helps somebody …
