In the post I want to declare that NDDD Sample application(s) is released and share the work with you. You can access it here: http://code.google.com/p/ndddsample. NDDDSample from functionality perspective matches DDDSample 1.1.0 which is based Java and on joint effort by Eric Evans' company Domain Language and the Swedish software consulting company Citerus. But because NDDDSample is based on .NET technologies those two implementations could not be matched directly. However concepts, practices, values, patterns, especially DDD, are cross-language and cross-platform :).

Start is a point where our brain accepts something or reject, or at least puts on the skeptic shelf.  So, a good start is always important. Agile methodology usually falls in reject set with people with waterfall thinking or who never *really* tried it. Why?..., I'm going to discuss to in this article, also how we can fix it by doing a practical exercise for introducing practical side of Agile to new comers.

In the post I want to discuss about two basic Domain-Driven Design premises which stand on the base of all other DDD principles, patterns, and practices. DDD principles, patterns, and practices described by Eric Evans are not something invented by him, but are something that were discovered and used long experience path by many folks. So, all DDD goodies have just two simple premises which I will cover in the post.

In the post I want to highlight very important event for IT community that happened in the Chisinau capital of Moldova. Also I want to discuss my view on the Chisinau’s IT field from knowledge sharing perspective.

In the post I want to present two useful utility classes that for a long time are used in Java world and developed within Apache Software Foundation. These are HashCodeBuilder and EqualsBuilder classes which were ported by me in C#. To implement a good method of Hash Code and Equals for any class is not an easy task, but the classes assists implementing object.GetHashCode and object. Equals.

In the post I want to discuss the practical part of the Builder pattern and how builder pattern usage and implementation can be simplified by Fluent Interface, it will show how these two patterns can leave in harmony with each other.

In the post I want to discuss basics of Rhino Security which was developed by Ayende. This is a nice security model implementation that could be easily integrated and adapted in many applications and scenarios. Intention of the post is to give good startup for Rhino Security. I will try to follow KISS (Keep It Simple) in my explanations, yes, I know that “It's All Relative” :) and also keep to minimum required infrastructure for the startup (mainly only required). Rhino Security is a part of Rhino tools, which is a set of already mature reusable classes and tools that cover various scenarios, such as well known:

Most of you already know what ReSharper is and its power; its shortcuts can improve productivity drastically. That is why I really recommend learning its basic keyboard shortcuts for persons that have already ReSharper license.
