PersistenceFramework

The main goal of this MongoDbContext is to achieve a level of abstraction over the MongoDb driver for Net Framework.

Observations:
The MongoDbContext need that every entity contains a public ObjectId Id { get; set; } property. You most declare each document collection like a private IMongoCollection<Entity> Entity { get; set; } property.
Persistence Framework simple example for MongoDb:

class Program
{
    static void Main(string[] args)
    {
        CustomDbContext context = new CustomDbContext("MongoDatabaseName", "127.0.0.1:27017");

        for (int i = 0; i < 10; ++i)
            context.Add(new Info { Data = i.ToString() + " aa" });

        IEnumerable<Info> infos = context.GetEntity<Info>(x => true);
        foreach (var info in infos)
            Console.WriteLine(info.Id + " " + info.Data);
        Console.WriteLine(context.GetEntity<Info>(x => x.Data == "1 aa").FirstOrDefault().Data);
    }
}

public class CustomDbContext : MongoDbContext
{
    public CustomDbContext(string databaseName, string url) : base(databaseName, url)
    {
    }

    private IMongoCollection<Info> Info { get; set; }
    private IMongoCollection<Data> Data { get; set; }
}


internal class Info
{
    public ObjectId Id { get; set; }
    public string Data { get; set; }
}

internal class Data
{
    public ObjectId Id { get; set; }
    public string Code { get; set; }
}
