+Summary: Client proxy has incorrect return type XmlElement instead of DataSet
+
+Description of Problem:
+
+The client proxy generated by mono for a web service has a return type of
+XmlElement instead of DataSet.  This is new to mono 1.1.9.
+
+Steps to reproduce the problem:
+1. A web method that returns a DataSet, e.g.:
+
+[WebMethod]
+public DataSet GetAllContacts()
+{
+}
+
+2. View the web service in a browser and click the link marked "Client
+proxy" (e.g. http://host/MyService.asmx?page=proxy).  Look at the return
+type for the web method.
+
+3. Alternatively, add a Web Reference to your VS.NET project then look at
+the Reference.cs file generated for it.
+
+Actual Results:
+
+Under mono 1.1.9:
+
+    public System.Xml.XmlElement GetAllContacts() {
+        object[] results = this.Invoke("GetAllContacts", new object[0]);
+        return ((System.Xml.XmlElement)(results[0]));
+    }
+
+Expected Results:
+
+As generated under mono 1.1.8:
+
+    public System.Data.DataSet GetAllContacts() {
+        object[] results = this.Invoke("GetAllContacts", new object[0]);
+        return ((System.Data.DataSet)(results[0]));
+    }
+
+How often does this happen? 
+
+Always.  Types such as bool and string are fine as is a custom type I use.
+ DataSet is affected.  I have not tried other types.
+
+Additional Information:
+
+Tested on RedHat 9 with mono 1.1.9, xps 1.1.9, mod_mono 1.1.9.  If I use
+the proxy generated by mono 1.1.8 to call web services running under 1.1.9,
+it works fine.
