注意  本指南基于 EGL 1.4 的 Khronos Group 开放式规范，可以在以下位置找到该规范： Khronos 原生平台图形界面（EGL 版本 1.4 - 2011 年 4 月 6 日 [PDF]。在装有 Visual Studio 2012 的 Windows 8 上编译时，所有 OpenGL ES 2.0 代码都采用 C/C++ 语法提供。本指南中未涉及语法中特定于其他平台和开发语言的差别。

注意  Windows 桌面应用使用不同的 API 来获取 Direct3D 交换链（如 D3D11Device::CreateDeviceAndSwapChain），并且不使用  CoreWindow 对象。
