C# 3.0 Auto Property And NHibernate

I was reading about NHibernate mapping of the properties that have no setter, and how it’s done through the backing field (reflection I assume). The setting looks like this:

access="nosetter.camelcase-underscore"
      column="name" type="string" length="20" />

And then I got curious what would be that with the new C# 3.0 auto properties.

As a test I made a simple class with a simple string property that looks like this:

private string test; public string Test { get { return test; } private set { test = value; } }

And with auto property this looks much sexier:

      public string Test { get; set; }

But what about backing field? Reflector shows the next:

[CompilerGenerated] private string k__BackingField;

public string Test { [CompilerGenerated] get; private[CompilerGenerated] set; }

t

Now I was wandering how  that should be communicated in the mapper file for NHibernate?… Googled…. nothing. Any ideas?
