RavenDB 4.0 storing raw json

Question

I'm using NLOG for logging with the JsonLayout and want to store these logs in RavenDB 4.0. Basically I'm trying to store raw json into ravendb using the RavenDB .NET client.

I had a working solution in RavenDB 3.5: using a class inheriting from "RavenJObject" but this functionality was depricated in 4.0.

I got it working by deserializing the json into a dynamic and storing the dynamic object. But this stores the document in a meaningless "JObjects" collection. It also seems overhead to convert json to dynamic and back to json again.

        var obj = JsonConvert.DeserializeObject<dynamic>(jsonString);
        session.Store(obj);

I know it's possible using the UI (raven studio). But i can't find a way doing it using the .Net client.

I think it's maybe possible using the http api, doing a post with the raw json. But I haven't found any documentation about this.

Who can help me out? Any advice is appreciated!

Here you have code sample which allows you to operate on generic type and assigns collection properly:

[Fact]
public void RawJson()
{
    using (var store = GetDocumentStore())
    {
        using (var session = store.OpenSession())
        {
            var json = "{ 'Name' : 'John', '@metadata' : { '@collection': 'Users' } }";
            var blittableJson = ParseJson(session.Advanced.Context, json);

            var command = new PutDocumentCommand("users/1", null, blittableJson);
            session.Advanced.RequestExecutor.Execute(command, session.Advanced.Context);
        }

        using (var session = store.OpenSession())
        {
            var user = session.Load<User>("users/1");
            Assert.Equal("John", user.Name);
        }
    }
}

public BlittableJsonReaderObject ParseJson(JsonOperationContext context, string json)
{
    using (var stream = new MemoryStream(Encoding.UTF8.GetBytes(json)))
    {
        return context.ReadForMemory(stream, "json");
    }
}

public class User
{
    public string Id { get; set; }

    public string Name { get; set; }
}
