Re: [nhibernate-development] Mapping by code

[Fabio Maulo]

For sure we can serialize Hbm* to have the XML.
In the code you can see the example in : MapDslTests.CreateXmlDemo.ShowXml()

And this is the result of that mapping (readable as written by hand using
NH's conventions):
<?xml version="1.0" encoding="utf-8"?>
