Adding signed Assembly to nHibernate

Question

Hello,

I'm working with nHibernate.

I have make an Assembly (ex : DAL.dll), which contains the mapping files (.hbm.xml) and the entities (.cs). This Assembly has a strong name (signed).

I created a console project, which reference the DAL assembly (DAL.dll).

When I try to instanciate the Configuration, it fails when loading my DAL Assembly.

The error is the following :

NHibernate.MappingException: Could not compile the mapping document: DAL.Mappings.Cat.hbm.xml NHibernate.MappingException: persistent class DAL.Cat, DAL not found

This is the console application code :

                        Configuration cfg = new Configuration();
                        cfg.SetProperty(Environment.ConnectionDriver, "NHibernate.Driver.SqlClientDriver");
                        cfg.SetProperty(Environment.ConnectionString, dsn);
                        cfg.SetProperty(Environment.Dialect, typeof(MsSql2005Dialect).AssemblyQualifiedName);
                        cfg.SetProperty(Environment.ProxyFactoryFactoryClass, typeof(NHibernate.ByteCode.Castle.ProxyFactoryFactory).AssemblyQualifiedName);
                        cfg.SetProperty(Environment.ShowSql, "true");
                        cfg.SetProperty(Environment.ConnectionProvider, typeof(DriverConnectionProvider).AssemblyQualifiedName);
                        cfg.AddAssembly(typeof(DAL).Assembly);

The problem is that the hbm.xml files are referencing the entities like that :

<class name="DAL.Cat,DAL">

Is there another solution than referencing each class with their full name (with the key, etc.)

Thanks !

A slightly cleaner way of specifying the mappings that can help you is:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                   namespace="DAL"
                   assembly="DAL assembly fully qualified name">
  <class name="Cat">
  ...

However, this should work even if the assembly name is not qualified. Try different combinations and see what happens.
