simple mongodb database context implementation

DbContext.cs

public class DbContext : IDbContext
{
    public DbContext(IRepositoryFactory repoFactory, string connectionString, string dbName)
    {
        if (string.IsNullOrWhiteSpace(connectionString))
            throw new ArgumentNullException("connectionString");
        if (string.IsNullOrWhiteSpace(dbName))
            throw new ArgumentNullException("dbName");

        this.Posts = repoFactory.Create<Entities.Video>(new RepositoryOptions(connectionString, dbName, "posts"));
        this.Users = repoFactory.Create<Entities.User>(new RepositoryOptions(connectionString, dbName,"users") );
        this.Tags = repoFactory.Create<Entities.Tag>(new RepositoryOptions(connectionString, dbName, "tags"));
        this.Taxonomies = repoFactory.Create<Entities.Taxonomy>(new RepositoryOptions(connectionString, dbName, "taxonomies"));
    }

    public IRepository<Entities.Post> Posts { get; private set; }
    public IRepository<Entities.User> Users { get; private set; }
    public IRepository<Entities.Tag> Tags { get; private set; }
    public IRepository<Entities.Taxonomy> Taxonomies { get; private set; }
}

On line one, it should be public class DbContext : IDbContext

nice catch, thanks!
