Visual Studio Library Overview
Visual Studio Library is a set of template-based C++ classes for simplifying the creation of VSPackages in native C++. Visual Studio Library includes complete source code, as a set of C++ header files. The header files are installed in Visual Studio SDK installation path\VisualStudioIntegration \Common\Source\CPP\VSL\Include\.
Visual Studio Library relies on the Active Template Library (ATL) for its support of COM objects. For more information, see Introduction to ATL.
Visual Studio Library supports unit testing, both for its own code and for your code. Some unit tests are included, as follows:
Visual Studio Library unit tests are installed in Visual Studio SDK installation path\VisualStudioIntegration\Common\Source\CPP\VSL\UnitTest\.
The base classes for unit tests for your code are in Visual Studio SDK installation path\VisualStudioIntegration\Common\Source\CPP\VSL\Include\VSLUnitTest.h.
Mock implementations of commonly-used COM and Visual Studio interfaces are in the header files, VSLMockSystemInterfaces.h and VSLMockVisualStudioInterfaces.h, which are installed in Visual Studio SDK installation path\VisualStudioIntegration\Common\Source\CPP\VSL\Include\.
