Downloading a PDF file from Fiddler to the WebAPI method results in 415 unsupported media type

Question

I am trying to load a PDF file into my WebAPI method, but I am getting 415 unsupported media type. Do I need to put something specific in my WebApiConfig.cs file to enable PDF formatting?

Here is the signature for my controller code:

[HttpPost]
        public HttpResponseMessage SavePdf(HttpPostedFileBase file)
        {
            string fileLocation = @"\\server\shared\appname\";
            ...

My WebAPI is currently hosted on localhost. I call this method WebAPI from Fiddler. Here's the Composer tab of Fiddler (then I click on the “Blue Upload File” link to download my PDF file):

This is where HTTP 415 error occurs in Fiddler:

It seems to me that I need to somehow say that my WebAPI accepts the type of PDF media file (application / pdf), but I'm not sure ... any ideas?

        try 
        {
            // Read the form data.
            await Request.Content.ReadAsMultipartAsync(provider);
