Is HttpWebRequest implemented differently in mono and .net?

Question

I am trying to port the c# cloudinary api to mono and I am having some problems building up the http request.

I have separated out this method for setting up the request but the HttpWebRequest.ContentLength turns out to be -1 in mono, but is .net the content is properly built.

I am running the newest Xamarin Studio on a Mac and I am building a MONO / .NET 4.0 library Mono version: 2.10.12

EDIT: Simplified code, this test passes in Visual Studio but fails in Xamarin studio

EDIT: Code is pushed to github if anybody would like to help

    [Test]     public void StreamTest()     {         var request = System.Net.HttpWebRequest.Create("http://foo.com");         request.Method = "POST";         request.ContentType = "application/x-www-form-urlencoded";         using (var writer = new System.IO.StreamWriter(request.GetRequestStream()))         {             writer.Write("anything");         }          Assert.IsTrue(request.ContentLength > 0);     } 

Answer 1

When you do

System.Net.HttpWebRequest.Create("http://foo.com"); 

you actually create an instance of the internal class System.Net.Browser.BrowserHttpWebRequest

Here is the inheritance hierarchy

System.Net.WebRequest
  System.Net.HttpWebRequest
    System.Net.Browser.PolicyBasedWebRequest
      System.Net.Browser.BrowserHttpWebRequest

The content length is handled in PolicyBasedWebRequest, initialized in ctor with -1 and never changed; I suggest you manually set it.
