PVS-Studio is a static analyzer that detects errors in source code of C/C++/C++11 applications. There are 3 sets of rules included into PVS-Studio: 1. Diagnosis of 64-bit errors (Viva64) 2. Diagnosis of parallel errors (VivaMP) 3. General-purpose diagnosis The PVS-Studio tool is intended for developers of contemporary applications and it integrates into the Visual Studio 2005/2008/2010 environment 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.

Spec Explorer is a software development tool for advanced model-based specification and conformance testing.

With Isolator++ technology, all these C/C++ unit testing issues go away. Isolator++ can simulate any dependency, by observing the running code, and diverting function calls to automatically generated mocks. Afraid of changing your code just in order to test it? Isolator++ can unit test any C/C++ code without modification. Wasting time rewriting C/C++ unit tests? Isolator++ tests are made to be shorter, clearer and resistant to production code changes. Isolator++ works on both Windows and Linux and with any test runner, including CppUnit, GoogleTest Boost and UnitTest++.

Android++ is a freely distributed extension and associated MSBuild scripts designed to enable Android application development within Visual Studio. Primarily for NDK based C/C++ applications, it also incorporates customisable deployment, resource management, and integrated Java source compilation.

Visual T# has been developed to simplify the design and the coding of unit tests for Microsoft.NET. Visual T# is a unit tests development environment integrated in Visual Studio™ (it also has a standalone version). This environment includes:
- T#: a programming language specialized for unit testing.
T# is based on C# v2, that makes its use really simple to .NET developers.
New keywords has been introduced to simplify test coding. And big emphasis has been placed on the definition of the test intention.
- Tools to compile, run and navigate through tests.
