+TargetMilestone: ---
+Summary: Web.Services returning null when XmlNode[] object casted to object from proxy code.
+Please fill in this template when reporting a bug, unless you know what you are doing.
+Description of Problem:
+I have a wsdl consumed web method that consumes a web service and casts the response to an 
+xtvdWebService#download", RequestNamespace="urn:TMSWebServices", 
+            public object download(string startTime, string endTime) {
+                System.Object[] response = this.Invoke("download", new object[] {
+                            startTime,
+                            endTime});
+                Console.WriteLine(response.Length);
+                Console.WriteLine(response[0]);
+                return (object)response[0];
+            }
+I manually added the Console writes to debug ( FWIW I dont have mono-debug working at the 
+moment ) and its telling me that response.Length is 1, and response[0] is null.
+(The object in the Microsoft implementation is a System.Xml.XmlNode[]).  When I run this in 
+mono; two things happen:
+First, its a fraction the speed of the microsoft implementation to download the data
+Second, the response is null.
+The exact same code and method works fine with the Microsoft .NET framework.  Doing pcap 
+dumps I can see that its making the request and getting the data back to the Invoke method, it 
+just never seems to return it back into the object[] array.
+Steps to reproduce the problem:
+1. Get a TMS Webservices account by going to http://labs.zap2it.com/ and using the certificate 
+code (DQYN-JQ2N-IBUT) 
+2. Go to the labs forum (http://bb.labs.zap2it.com) and download the xtvdWebService.cs file 
+there (this is the file I'm using)
+3. Write a small wrapper to call it and observe the fact that the return value is null.
+Actual Results:
+The mono web.services implementation returns a null value from this.Invoke.
+Expected Results:
+The microsoft .net framework (v1.0 and v1.1) return a System.Xml.XmlNode[] casted to an object 
+by the wrapper.
+How often does this happen? 
+Every time.
