Few months ago I blogged about the release of NDepend v3 Continuous Integration and Reporting Capabilities here. Recently, the NDepend team has released v4 which comes with code rules based on C# LINQ queries (CQLinq), this make code ruling so much more powerful and flexible.

There are couple of new rules available like:

• http://www.ndepend.com/DefaultRules/webframe?Q_UI_layer_shouldn't_use_directly_DB_types.html
• http://www.ndepend.com/DefaultRules/webframe?Q_Types_with_disposable_instance_fields_must_be_disposable.html
• http://www.ndepend.com/DefaultRules/webframe?Q_Avoid_the_Singleton_pattern.html
• http://www.ndepend.com/DefaultRules/webframe?Q_Avoid_making_complex_methods_even_more_complex_(Source_CC).html

v4 also provides NDepend.API and a dozen of open-source code tool developed with NDepend.API (the Power Tools)
