+Product: Mono/Class Libraries
+Version: unspecified
+OS Details:

+TargetMilestone: ---
+Summary: Missing WebException.Response property.
+When a call to HttpWebRequest.GetResponse() results in a WebException 
+being thrown, the Response property of this exception is NULL when, 
+in .NET, it is set to an instance of HttpWebResponse. 
+This means that it is not possible to determine the HTTP status code 
+returned in MONO (this is indicated by the StatusCode property of the 
+nonexistent HttpWebResponse object).
+This is new behaviour in Release 0.24... HttpWebResponse.GetResponse() 
+never used to throw a WebException at all, but this was changed to improve 
+consistency with .NET.
+Steps to reproduce the problem:
+1. Please see sample program
+Actual Results:
+Unhandled Exception: System.NullReferenceException: A null value was found 
+where an object instance was required
+in <0x00116> 00 .HttpTest:Main (string[])
+(Output obtained by running the sample program in MONO 0.24).
+Expected Results:
+Server returned error: NotFound
+(Output obtained by running the sample program in .NET).
+How often does this happen? 
+Always in MONO, never in .NET.
+Additional Information:
+-----Sample program starts here-----
+using System;
+using System.Net;
+public class HttpTest
+	public static void Main(string[] args)
+	{
+		try
+		{
+			HttpWebRequest httpreq = (HttpWebRequest)
+			HttpWebResponse httpresp = (HttpWebResponse)
+			// Expect WebException to be thrown by now.
+			Console.Out.WriteLine("Eh?... This page shouldn't 
+		}
+		catch (WebException e)
+		{
+			// Something went wrong! So what's the status code?
+			HttpWebResponse badresp = (HttpWebResponse)
+			Console.Out.WriteLine("Server returned error: " + 
+badresp.StatusCode); // Exception is thrown here, because e.Response is 
+null (at least it is in MONO).
+		}
+	}
+-----Sample program ends here-----
