RavenDb and protecting the collection in a document/entity

Hi I'm used to have the following entity

public class Foo
{
    private IList<Bar> _bars;

    public IEnumerable<Bar> Bars { get { return bars; } }

    public void Add(Bar bar)
    {
        /* Validation logic here */

        _bars.Add(bar);
    } 
}

I'm suspecting this won't work with RavenDb or am I'm wrong? Can I keep my collection with Bars protected from outside manipulating (in other words not allowing foo.Bars.Add(bar);)

A private setter on an automatic property is the easiest and most readable way without doing anything special.

public class Foo
{
    public IEnumerable<Bar> Bars { get; private set; }

    public void Add(Bar bar)
    {
        Bars.Add(bar);
    }
}

Another way would be with attributes:

// pick one or the other
using Newtonsoft.Json // on 1.0
using Raven.Imports.Newtonsoft.Json // on 2.0

...

public class Foo
{
    [JsonProperty(PropertyName = "Bars")]
    private IList<Bar> _bars;

    [JsonIgnore]
    public IEnumerable<Bar> Bars { get { return bars; } }

    public void Add(Bar bar)
    {
        _bars.Add(bar);
    }
}

I found the solution to use two properties.

public IEnumerable Bars { get { return InnerBars; } }

private List InnerBars { get; set; }}
