[英]Is Visual-C++-2017 binary compatible with VC++-2015?
史蒂夫告诉我VC 2015 和 VC 2017 实际上（将是）二进制兼容。
我发现零信息wrt。 这在2017 (RC)的发行说明中- 或者几乎任何地方，所以这里是：
Visual Studio 2017 (v141)和Visual Studio 2015 (v140)之间的运行时差异是什么（如果有Visual Studio 2015 (v140) ？ (*) (*)：是的，我实际上继续安装了 2017 RC，从表面上看，至少使用了相同的MSVCRT，即msvcp140.dll和vcruntime140.dll （尽管调用了平台工具集“v141”。
是的，141 和 140 库几乎相同。 该版本因并行问题而受到撞击。 VisualC++ 2015 中的 v140 工具集和 VC++ 2017 中的 v141 工具集是二进制兼容的。
是的，visual 2019(14.2)、2017(14.1)、2015(14.0)都是二进制兼容的，都是14.x版本。 在https://docs.microsoft.com/en-us/cpp/porting/binary-compat-2015-2017?view=vs-2017上查看更多信息。 新版本添加了一些新功能或补丁。
以下是2017年和2019年的文件，可以找到2019年新增的文件。

因为我无法安装 2015 文件。 我提取它（ D:\\apps\\wix311-binaries\\dark.exe -nologo -x "D:\\tmp\\vcredist_x64-2015" "C:\\Users\\Liu.DH\\Downloads\\vc_redist.x64-2015.exe" )，您可以找到以下文件。

Microsoft 一直在以增量方式更新其 CRT。
Visual C++ 14.0 (2015) CRT 有 4 个文件：
Visual C++ 14.1 (2017) CRT 仅添加 2 个文件：
Visual C++ 14.2 (2019) CRT 仅添加 2 个文件：
如果不使用上面列出的某些附加功能，则二进制文件可以与旧版本的 C 运行时一起使用。
