Ok, but in this case I don't have to call another constructor, but a
static method. Then the binding should be done on GetInstance method.

I got that from some conversation by the developers on the micrososft site.
The main issue I have run into is typed dataTables are not serializable.
Most people (including my self) use GetChanges and send the Dataset but this
sends an untyped dataset.

True but the whole idea of XML is so it is easy to communicate with other
systems . Just send them the XML and let them use it as they would and other
piece of data. Nobody would write a Java version of a Dataset nor do you
need to - just send the XML back.
This works well with clients and partn

I didn't think remoting was allowed in a partially trusted environment

you could create the XmlTextReader on a stream, and can reset that
stream, like this:
FileStream xmlFile = new FileStream('books.xml');

Why not just create a new instance?

Do you Yahoo!?
Faith Hill -
The big, nasty overload of CreateInstanceAndUnwrap allows you to use a
constructor other than the default.
public object CreateInstanceAndUnwrap(
string assemblyName,
string typeName,
bool ignoreCase,
BindingFlags bindingAttr,
Binder binder,
object[] args,
CultureInfo culture
Well, the problem remains even if I move forward.
I have another question.
How can I make a Clone for XmlTextReader object ?

Getti the definition of XmlTextReader from SDK doc you can't go back on

2) Use an XPathDocument (XPathNavigator) getting specific
