.net object persistence

Question

Can you please suggest a free, open source or low cost .net object persistence framework? I am not looking for ORM tools like NHibernate or Entity Framework. The closest commercial product that describes my need is fastobject.net framework. Thanks.

oh..sorry..I am new to SF. Thanks for reminding. Would remember in future. Thanks. — Ajit Singh, Dec 11 '09 at 01:34

Karvonite. It promises to be simple and non-invasive, but I haven't used it myself.

That's only hosted at Microsoft. It's not written by Microsoft. – John Saunders Dec 05 '09 at 15:15
Thanks for the notice. I suppose it is MP Advanced Multimedia, but their website is only orange at the time... – Cecil Has a Name Dec 05 '09 at 15:28

Try db4o at www.db4o.com. It was recently acquired by Versant.

Some pro's: It's open source with code available in java and c#. The framework is dead easy to use. The community is quite nice and you can get answers quickly on the forums.

Between Karvonite and db4o, which one is better? – Ajit Singh Dec 09 '09 at 12:16
I'd say db4o is more mature but then again MS knows how to play catch-up. Db4o to me is easier to use as there's no need to build a persistence model and it knows how to deal with missing assemblies. I haven't seen any performance benchmarks that include both so hard to say which is faster. As a db4o MVP i favor db4o :) – Goran Dec 09 '09 at 13:07

You could have a look at SubSonic, goes not as deep as NHibernate does in the sense of being a 'real' ORM tool but when it comes to persistence it serves it's purpose very well.

.Net SOP - Scalable Object Persistence (v4.5) is what you are looking for. Scalable, Stable and lightweight, low-memory req't and housed in a single DLL. It supports rock solid transaction (app crash, power-failure, etc... it will recover, rollback to previous committed state) and very scalable (100 million inserts in 2+ hrs using an avg laptop). It is Free, Open Source (LGPL 2.1 license) and Royalty Free redistribution, link: http://sop.codeplex.com.

This is the very 1st managed code achieving this performance + stability level. No comparison... you've got to read the product feature set and try it.
