NHibernate type does not have an implementation

Question

I'm upgrading a solution I create about 4 years on 3.3.2.4000 to 4.0.4.4000. When I try to bring it up I get the following error:

{"Method 'Set' in type 'iSeguro.Data.Mappings.EmpresaBridge' from assembly 'iSeguro.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.":"iSeguro.Data.Mappings.EmpresaBridge"}

The type definition is as follows:

public class EmpresaBridge : IFieldBridge
{
    public void Set(string name, object value, Document document, Field.Store store, Field.Index index, float? boost)
    {
        string data = string.Empty;
        if (value != null) data = ((Empresa)value).Nombre;
        document.Add(new Field(name, data, store, index));
    }
}

The mapping type:

public partial class ValoracionSearchMap : DocumentMap<Valoracion>
{
    public ValoracionSearchMap()
    {
        Name("Valoracion");
        Id(c => c.Id);
        Map(c => c.Asunto).Store().No().Index().Tokenized().Boost(4);
        Map(c => c.Descripcion).Store().No().Index().Tokenized();
        Map(c => c.Publicar).Store().Yes().Index().Tokenized();

        Map(c => c.Creador).Store().Yes().Index().Tokenized();
        FieldBridge(c => c.Creador).Custom<UsuarioBridge>();

        Map(c => c.Empresa).Store().Yes().Index().Tokenized();
        FieldBridge(c => c.Empresa).Custom<EmpresaBridge>();

        Map(c => c.Producto).Store().Yes().Index().Tokenized();
        FieldBridge(c => c.Producto).Custom<ProductoBridge>();
    }
}

I've been out of the game for a while and just have no idea what the error is relating. This is suppose to hook objects with lucene.net.

Thanks!

Check your dll versions. This might be an old reference to the project that implements IFieldBridge.

1. Remeve references to your own projects under Project > References
2. Close the solution and delete all 'bin' and 'obj' folders in your project folders
3. Rebuild all projects
