I’m setting up a new solution to map against SQL data that has been imported from an Access database. Auto Mappings work fine against the entities I have defined but I need to be able to use the Fluent mapping type to give access to the .NotFound.Ignore extension.
I have used exactly the same syntax in another project (I think!) which works fine. Have I made a schoolboy error to cause the “Unsupported mapping type ‘IT.Classes.Entities.Admin'”? Any help is much appreciated.
DDL:
CREATE TABLE [dbo].[Admin](
[ID] [int] NOT NULL,
[primaryEmail] [nvarchar](50) NULL,
[secondaryEmail] [nvarchar](50) NULL,
[highPriorityEmail] [nvarchar](50) NULL,
[MobileEmail] [nvarchar](50) NULL,
[EmailUser] [bit] NOT NULL,
[HelpDeskMessage] [nvarchar](max) NULL
) ON [PRIMARY]
Entity:
namespace IT.Classes.Entities
{
public class Admin
{
public virtual bool EmailUser { get; set; }
public virtual string HelpdeskMessage { get; set; }
public virtual string HighPriorityEmail { get; set; }
public virtual int Id { get; set; }
public virtual string MobileEmail { get; set; }
public virtual string PrimaryEmail { get; set; }
public virtual string SecondaryEmail { get; set; }
}
}
Mapping:
using FluentNHibernate.Mapping;
using IT.Classes.Entities;
namespace IT.Classes.Mappings
{
public sealed class AdminMap : ClassMap<Admin>
{
public AdminMap()
{
this.Id(x => x.Id);
this.Map(x => x.EmailUser);
this.Map(x => x.HelpdeskMessage);
this.Map(x => x.HighPriorityEmail);
this.Map(x => x.MobileEmail);
this.Map(x => x.PrimaryEmail);
this.Map(x => x.SecondaryEmail);
}
}
}
Session Factory:
private static ISessionFactory CreateItHelpdeskSessionFactory()
{
return
Fluently.Configure().Database(
MsSqlConfiguration.MsSql2008.ConnectionString(
ConfigurationManager.ConnectionStrings["ITHelpdesk"].ConnectionString))
.Mappings(m => m.FluentMappings.Add<Admin>())
.Mappings(m => m.FluentMappings.Add<Applications>())
.Mappings(m => m.FluentMappings.Add<Category>())
.Mappings(m => m.FluentMappings.Add<Log>())
.Mappings(m => m.FluentMappings.Add<Multipliers>())
.Mappings(m => m.FluentMappings.Add<Os>())
.Mappings(m => m.FluentMappings.Add<Priority>())
.Mappings(m => m.FluentMappings.Add<Request>())
.Mappings(m => m.FluentMappings.Add<Status>())
.BuildSessionFactory();
}
EDIT
I thought I would export the auto mappings to see if they would highlight a problem in my fluent mappings but they seem to be correct:

In your configuration code, the types mentioned in the Fluent Mappings should be the map classes, not the classes being mapped.
That is, instead of:
You need to say:
Even better, to avoid having a separate line for every class map, use the .AddFromAssemblyOf<>() method, which uses reflection to add all class maps from a given assembly:
