Microsoft released the C# programming language and the .NET development platform in 2002 to offer a more powerful, more flexible, and simpler programming model than that provided by the COM (Component Object Model) or C++/WinAPI programming models. Since then, C#/.NET has become the mainstay of modern day desktop software development, offering high level coding, more productivity, rich frameworks and services, support for modern customer experiences, and cross platform maintenance of assets.
In the context of desktop application development, however, C++/WinAPI software development still has the advantage over C#/.NET of providing the highest levels of performance, managing resources or memory layout explicitly, accessing hardware-level optimization opportunities, and more readily taking advantage of existing freely available, high-quality, peer-reviewed C/C++ libraries.
I have developed .NET Class Libraries for the Microsoft Windows platform. These .NET Class Libraries provide reliable computational capabilities by utilizing freely available, high-quality, peer-reviewed C/C++ libraries. Windows desktop application developers can use these libraries to create their .NET applications.
These libraries combine the advantages of both C++/WinAPI and C#/.NET software development by implementing .NET components using C++/WinAPI and packaging these components in .NET Class Libraries. These computational components can the be accessed by C#/.NET high-level application software in combination with the other .NET frameworks and services provided by the .NET platform.
