How to set default access to field.camelcase-underscore using Fluent NHibernate?

Question

would like to set this convention up globally if possible.

Answer 1

You need a convention, of which there are some shortcuts for the common scenarios. Specifically, there's a DefaultAccess shortcut, with a CamelCaseField(prefix) method.

.Conventions.Add(
  DefaultAccess.CamelCaseField(CamelCasePrefix.Underscore)
);
