nhibernate HbmMapping to Xml

I am using NHibernate mapping-by-code to map the classes.

Sometimes, in order to debug my NHibernate configuration, I would require to check exactly what were the settings passed over to NHibernate, and it is quite difficult do debug the mapping-by-code.

Is there any way where you could convert the generated HbmMapping, back into the Xml file, just as if typed by hand?

This would help a lot in diagnosing if the problem is lying from my mappings!

Option 1

Be warned this will write the XML into your BIN folder causing the IIS pool to recycle, so run once and then comment the WriteAllXmlMapping line back out!

var mapper = new ModelMapper();
mapper.AddMappings(typeof(CmsMeta).Assembly.GetTypes());

//This will write all the XML into the bin/mappings folder
mapper.CompileMappingForEachExplicitlyAddedEntity().WriteAllXmlMapping();

Option 2

This will give you a a single large XML file that you can add a breakpoint to.

var mapper = new ModelMapper();
mapper.AddMappings(typeof(CmsMeta).Assembly.GetTypes());
var mapping = mapper.CompileMappingForAllExplicitlyAddedEntities();

//you could add a breakpoint here! 
var mappingXml = mapping.AsString();

The source is from a blog post I wrote a while ago.
