First feature in D9.NHibernate: DescribedEnumStringType

That's a generic IUserType for mapping enum columns using the descriptions of values instead of their names.

It depends on D9.Commons which contains the Described Enum helpers described in an early post

Usage:

given the following enum:

using System.ComponentModel;

namespace OpenUni.Domain.Modules
{
    public enum ModuleTypes
    {
        [Description("ר")]
        Standard,

        [Description("מ")]
        Advanced,

        [Description("מס")]
        AdvancedSeminar,

        [Description("תש")]
        Masters
    }
}

mapping a field of type ModuleTypes will look like that:

<property
    name    = "ModuleType"
    column  = "ModuleType"
    type    = "D9.NHibernate.UserTypes.DescribedEnumStringType`1[[OpenUni.Domain.Modules.ModuleTypes, OpenUni.Domain]], 
              D9.NHibernate" />

or if you use Castle ActiveRecord attributes for mapping:

[Property(ColumnType = "D9.NHibernate.UserTypes.DescribedEnumStringType`1[[OpenUni.Domain.Modules.ModuleTypes, OpenUni.Domain]], D9.NHibernate")]
public virtual ModuleTypes ModuleType {get; set;}

I'll build and upload binaries once I get some time for that. meanwhile you should be able to just svn-co the code, then nant from the root. (assuming nant 0.86b2 and .net 3.5 on the machine)
