Libraries Acquisition 80% of C++ projects use 2 or more 3rd party libs A majority of them use open source libraries Acquiring and rebuilding libs on Windows can be simple NuGet wasn’t designed for C++, e.g. no local rebuilding Open source tool based on a port tree approach (Vcpkg) Usage: vcpkg install boost Installs the.h,.lib and binaries in a “lib folder” ready to use

C++ Conformance C++11 C++14 C++17 Expression SFINAE (via more libraries) Two-phase Name Lookup* Extended Constexpr NSDMI for Aggregates Expression SFINAE (via Boost) Attribute [[fallthrough]]** Terse static_assert** Generalized range-based for-loops …

Compiler switches [easing your upgrade process] /permissive- Introducing the idea of a “less permissive mode" in the compiler Off by default now… on by default at some point in the future /std:c++14 On by default, for now The latest blessed C++ standard i.e. standards features up to C++14 /std:c++latest Off by default, for ever Every implemented feature that is not part of a finalized standard yet

Example libraries that we couldn’t compile previously Most Boost MSVC workarounds can be removed BOOST_MSVC_SFINAE_EXPR - now BOOST_NO_CXX14_AGGREGATE_NSDMI - VS15 Preview 4 BOOST_NO_CXX14_CONSTEXPR, BOOST_NO_CXX14_VARIABLE_TEMPLATES - VS15 RC Boost.Spirit X3 parser framework - VS15 RC Sprout constexpr containers/algorithms - VS15 RC Range-V3 (MSVC compatible version) Crow micro web framework GoogleTest (for C++11) JSON for Modern C++ (nlohmann github version)...

Build Throughput Faster builds (with improved linking) VS2015 Update 3 When opting for /debug:fastlink, 2-4x faster, e.g. Fable, Forza, Chrome, Bing Maps Standalone tool (mspdbcmf.exe) to generate FULL PDB for binary VS “15” On by default, further improves link times by 30% (over VS2015 U3) mspdbcmf.exe integrated as part of the Visual Studio build experience IncrediBuild extension Generates an improved build plan which breaks down false dependencies Intelligent dynamic resource management (up to 8 cores with the FREE extension) e.g. Qt from 942 to 844 seconds e.g. ACE from 392 to 282 seconds Build visualization and diagnostic tools to find build bottlenecks
