PostSharp is the #1 pattern-aware extension to C# and VB. It allows developers to eradicate boilerplate by offloading repeating work from humans to machines. PostSharp contains ready-made implementations of the most common patterns and gives you the tools to build automation for your own patterns. Developers usually think in terms of design patterns, but with conventional programming languages, they end up writing boilerplate code. PostSharp extends the C# and VB languages with a notion of pattern. The result: shorter, cleaner code that’s easier to write and understand, contains fewer defects and is less expensive to maintain.

DIRegEx is a library of components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl for Delphi (Embarcadero / CodeGear / Borland).

The PVS-Studio tool is intended for developers of contemporary applications and it integrates into the Visual Studio 2015, 2013, 2012, 2010, 2008, 2005 environments providing the programmer with a convenient user interface to analyze files, navigate through code and get reference information. You do not need to study documentation and settings preliminarily to work with the analyzer. The analyzer is ready to work right after it is installed.
