Something is wrong with my MongoConfiguration I think, I read the following on NoRM's google group:

It can easily live in the object:

public class POCO{

       f.ForProperty(p=>p.AnotherLongProperty).UseAlias("B");

In my class I have

public class Item
{
    static Item()
    {
        MongoConfiguration.Initialize(
            cfg=> cfg.For<Item>(
                c => {
                    c.ForProperty(i => i.Name).UseAlias("N");
                    c.ForProperty(i => i.Description).UseAlias("D");
            })
        );
    }
    public String Name { get; set; }
    public String Description { get; set; }
}

After I save them there are items in DB with short key namse, the problem is when I try to read up all previously created items on start I get no items back.
