Index Creation Failing for ShardedDocumentStore and Sharded Linq Queries Not Supported

Question

I just implemented sharding with RavenDB. When running it for the first time, this code:

tempShardedDocumentStore = new ShardedDocumentStore(new ShardStrategy(), shards);
tempShardedDocumentStore.Initialize();

IndexCreation.CreateIndexes(typeof(RavenDataAccess).Assembly, tempShardedDocumentStore);

... produces this error:

System.TypeInitializationException: The type initializer for 'WriteToRaven.Data. RavenDataAccess' threw an exception. ---> System.NotSupportedException: Sharded document store doesn't have a database commands. you need to explicitly use the shard instances to get access to the database commands

First, ShardedDocumentStore does indeed have DatabaseCommands:

Second, if that just won't work, should it be done like this?

IndexCreation.CreateIndexes(typeof(RavenDataAccess).Assembly, shards[0]);

If so, now my linq query won't work:

System.NotSupportedException: Sharded linq queries aren't supported currently at Raven.Client.Shard.ShardedDocumentSession.QueryT

using (IDocumentSession ravenSession = GetRavenSession())
{
    return ravenSession.Query<T>().OrderByDescending(orderByClause).FirstOrDefault();
}

How do I get this to work?

Note: GetRavenSession() returns OpenSession() from the sharded document store shown above.

Bob Horn, What build are you using? We recently revamped the sharding support. We have support for linq in sharding now, as well as creating indexes.
