The fastest means in data transmission is binary. So, I suggest that  you find a binary example using ASP.NET WebAPI.

Should we assume the requirement is to transfer a file using C# over HTTP; multipart/form-data?

The ASP.NET Core docs explain how to handle file uploads.  I recommend you read the openly published documentation and select an option that best fits your requirements.

https://docs.microsoft.com/en-us/aspnet/core/mvc/models/file-uploads?view=aspnetcore-2.2

Please show the code that you have written up to this point, explain any issues you are having as well as what "really fast" means.

MVC 5 is the real bottleneck as it is much slower than MVC core. the faster file retrieval would be to use IIS static file handler instead of MVC, but if you use MVC then something like:

public class DownloadsController : Controller
{
    public FileResult File(string path)
    {
       var fullPath = HostingEnvironment.MapPath(path);
       return File(fullPath, "content-disposition");
    }
}

I have the bytes in stream but there are Content-Length:0 and empty body in Response.

There must be a bug in your code. Share your code if you need help debugging.
