[Mono-list] XmlIncludeAttribute missing class

[Chris Turchin]

Hi,

Sorry, I did not see that the Hashtable was private.

What I noticed when I tried your sample code is that if I decorate the
Configuration class with the XInclude's, then the error does not
occur...

[Serializable]
[XmlInclude (typeof (Folder))]
[XmlInclude (typeof (Site))]
public class Configuration {

##########

$> mcs ser.cs
$> mono ser.exe
$> more test.xml
=EF=BB=BF<?xml version=3D"1.0" encoding=3D"utf-8"?>
<Configuration xmlns:xsd=3D"http://www.w3.org/2001/XMLSchema"
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance">
  <Sites>
    <anyType xsi:type=3D"ArrayOfAnyType1" />
  </Sites>
</Configuration>

Perhaps that was the issue?

Regards,
--chris
