1  // pch.h: This is a precompiled header file.
 2  // Files listed below are compiled only once, improving build performance for future builds.
 3  // This also affects IntelliSense performance, including code completion and many code browsing features.
 4  // However, files listed here are ALL re-compiled if any one of them is updated between builds.
 5  // Do not add files here that you will be updating frequently as this negates the performance advantage.
