Visual Studio 2017 (15.9 update) is now available for download, and you should see the 'new update available' notification in the coming weeks--you can also get the update now by downloading the 'free trial' version of the installer which will let you update your system. This release includes support build ARM64 UWP apps and C++17
<charconv> for float.
Note that 15.9 is the last minor update for VS 2017, although it will continue to get servicing updates. The VS 2017 Preview channel has been updated to match VS 2017 (15.9).
Compiler and CRT
VS 2017 (15.9) includes a new version of the C/C++ complier (19.16.27023.1). This includes a number of bug fixes as well as language conformance improvements. See this blog post for more details, as well as Microsoft Docs.
Note: Per this blog post, the
_MSC_VER value is now 1916 instead of 1910, 1911, 1912, 1913, 1914, or 1915.
Servicing: 15.9.2 updates the C++ compiler to 19.16.27024.1. 15.9.4 updates the C++ compiler to 19.16.27025.1. 15.9.5 updates the C++ compiler to 19.16.27026.1. 15.9.7 updates the C++ compiler to 19.16.27027.1.
The C/C++ Runtime (14.16.27012) is included in this update. Remember that VS 2015 and VS 2017 share the same runtime redistributable binaries and that VS 2015 Update 3 is binary compatible with VS 2017--code or static library built with one can be linked to the other--, so this is the latest version for both.
GitHub: The Direct3D Game UWP templates on directx-vs-templates now including the ARM64 platform configurations when using VS 2017.
Windows 10 SDK: This release includes the Windows 10 SDK (October 2018) which was also available an optional component for VS 2017 (15.8.6 or later).
