Is there mongodb C# driver support System.Dynamic.DynamicObject in .NET 4?

Question

Im working on a project that use .NET Razor and mongodb. I would like to do something like this:

@{
    var feeds = DP.Database.GetCollection("feeds").FindAll();
}
<ul>
    @foreach (dynamic feed in feeds)
    {
        <li>@feed.message - @feed.from.name</li>
    }
</ul>

However, the current mongodb C# driver FindAll() return collection of BsonDocument which does not support dynamic object. Anybody know a .NET 4 dynamic supported mongodb C# driver?

Thanks a lot

Currently, there is no support for dynamic in the MongoDB driver. This is because it is based on .NET 3.5. However, since a .NET 4.0 assembly can reference a .NET 3.5 assembly, it is possible for you to write a IBsonSerializationProvider and an IBsonSerializer in .NET 4.0 to support dynamics.

We, 10gen, are looking at doing this in the future. I have spiked some support at https://github.com/craiggwilson/mongo-csharp-driver/tree/dynamic if you want to take a look. There are most definitely bugs, but it shows that it is possible.
