+Summary: incompatible serialization/deserialization of System.Guid class between ms.net and mono using BinaryFormatter
+
+Description of Problem:
+
+incompatible serialization/deserialization of System.Guid class between 
+ms.net and mono using BinaryFormatter
+
+Steps to reproduce the problem:
+
+using System;
+using System.IO;
+using System.Runtime.Serialization.Formatters.Binary;
+
+namespace GuidTest
+{
+	class GuidTest
+	{
+		const string filename = "guid.bin";
+		static void Main(string[] args)
+		{
+			BinaryFormatter f = new BinaryFormatter();
+			if(File.Exists(filename))
+			{
+				Guid guid = (Guid)f.Deserialize(new 
+FileStream(filename, FileMode.Open));
+				Console.WriteLine(guid.ToString());
+				Console.ReadLine();
+			}
+			else
+			{
+				f.Serialize(new FileStream(filename, 
+FileMode.CreateNew), Guid.Empty);
+			}
+		}
+	}
+}
+
+
+
+1. Run program under ms.net (generate guid.bin file)
+2. Run program under mono (using generated guid.bin file)
+
+Actual Results:
+
+Unhandled Exception: System.Runtime.Serialization.SerializationException:
