Can I automap a tree hierarchy with Fluent NHibernate?

I wish this help you This is probably because your conventions creates foreign keys as "class name" + "Fk". So you get same FK column for both Manager and Manages properties. You can override conventions so that FK column includes property name and thus you''ll get EmployeeManagerFk and EmployeeManagesFk. Or include both left/right side classes, too (EmployeeManagerInEmployeeFk), etc.
See here on how to override conventions. Or you can override HasMany/ManyToMany conventions to have different setup. Read FNH docs, look in google, read sample code - conventions are not always easy to understand and get to work.

hop of those help? The default convention is not to add the inverse attribute. You will have to overwrite the convention to change that.

I hope this helps . ok, after a few googling, i figured out the solution:
this is a many-to-one relation and it is mapped using Reference() Method, and the auto mapping already do that:
code :
References<Worker>(m => m.Worker);

This might help you You are not supposed to directly use ObservableListType in your classes and mappings (use ICollection, IList, etc)
Instead, you need to use WpfCollectionTypeFactory as the collection type factory.
code :
.ExposeConfiguration(cfg => SetProperty(Environment.CollectionTypeFactoryClass,
                         typeof(WpfCollectionTypeFactory).AssemblyQualifiedName))

This might help you Using IReferenceConvention instead overriding GetKeyName in ForeignKeyconvention class solved the problem.
Fluent NHibernate AutoMap CultureInfo

around this issue To use NHibernate's mapping support for CultureInfo (which is there, see https://github.com/nhibernate/nhibernate-core/blob/c85d038dce8ba87bd3f4de2458b4ef6e2497f7f8/src/NHibernate/Type/CultureInfoType.cs), you'll need to tell Fluent NHibernate you want to use it by means of the following convention:
code :
using System.Globalization;

using FluentNHibernate.Conventions;
using FluentNHibernate.Conventions.AcceptanceCriteria;
using FluentNHibernate.Conventions.Inspections;
using FluentNHibernate.Conventions.Instances;

public class CultureInfoConvention : IUserTypeConvention
{
    public void Accept(IAcceptanceCriteria<IPropertyInspector> criteria)
    {
        criteria.Expect(n => n.Property.PropertyType == typeof(CultureInfo));
    }

    public void Apply(IPropertyInstance instance)
    {
        instance.CustomType("CultureInfo");
    }
}
