Visual Studio 2017 Version 15.5, Visual Studio for Mac Released

• https://blogs.msdn.microsoft.com/visualstudio/2017/12/04/visual-studio-2017-version-15-5-visual-studio-for-mac-released/

まとめ

• NETMFの縮小版 • Visual Studio 2017対応 • ３つのファイルでポーティング（STM32F4） • ポーティングのデバッグ大変 • C/C++を呼び出し可能 • VS2017 15.5は運用回避
