Description curious_freddy 2016-07-26 13:45:33 UTC
On Windows using .Net the C14N transformed XML contains the included namespace prefixes in the transformed XML. On Mono these namespaces are not present in the transformed XML even though the inclusiveNamespacePrefixList constructor overload is used.

Sample code demonstrating this follows:

using System;
using System.Diagnostics;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using System.Security.Cryptography.Xml;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace TestXmlDsigExcC14NTransform
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			string xml = @"<root xmlns:foo=""tempuri.org"">some test content</root>";

			var element = XElement.Parse(xml);
			string inclusiveNamespacePrefixList = "foo";
			var transform = new XmlDsigExcC14NTransform(inclusiveNamespacePrefixList);
			using (var stream = new MemoryStream()) 
			{
				element.Save (stream, SaveOptions.DisableFormatting);
				stream.Position = 0;

				transform.LoadInput (stream);
				var transformOutput = (MemoryStream)transform.GetOutput();

				XElement transformedXml = XElement.Load(transformOutput, LoadOptions.PreserveWhitespace);
				var transformedXmlString = transformedXml.ToString();
				if (!transformedXmlString.Equals(xml, StringComparison.Ordinal)) 
				{
					Console.WriteLine ("These two are equal on .Net but not on Mono.");
				}
			}
		}
	}
}
