Containers are a great tool for configuring reproducible build environments. It’s fairly easy to find Dockerfiles that provide various C++ environments. Unfortunately, it is hard to find guidance on how to use newer techniques like multi-stage builds.
August 14, 2018Aug 14, 201808/14/18Containers allow developers to package up an application with all the parts it needs, such as libraries and other dependencies, and ship it all out as one image. This is especially useful for C++ cross-platform development – with containers you can choose to target a platform that runs on a completely different operating system than your developer machine.
August 13, 2018Aug 13, 201808/13/18Containers encapsulate the runtime environment of an application: the file system, environment settings, and virtualized OS are bundled into a package.

We have just released our fifth out-of-band update of Clang/C2 toolset. As always, this release has been driven by your feedback. While we’ve heard a lot of feature requests the one’s we’ve heard most frequently are that you want Clang 3.8 and you want x64-hosted compilers.
April 6, 2016Apr 6, 201604/6/16The Visual C++ team has shipped three releases of Clang with Microsoft CodeGen (Clang/C2). We’ve got a solid pre-production compiler that passes all of our STL tests and compiles a bunch of code into native Windows binaries. We’ve about to move to the 3.8 release of clang.
January 20, 2016Jan 20, 201601/20/16We have just released an out-of-band update of Clang/C2 toolset that brings in some of the community fixes as well as bugs found from testing. This is one of many rapid releases to come in the future, and issues reported from customers will be addressed progressively.

Overview
Update 1 for Visual Studio 2015 was announced on November 30, 2015.
faster
November 5, 2019Nov 5, 201911/5/19C++ builds should always be faster. In Visual Studio 2019 16.2, we’ve shown our commitment to this ideal by speeding up the linker significantly. Today, we are thrilled to announce a new collection of tools that will give you the power to make improvements of your own.
July 25, 2019Jul 25, 201907/25/19On the C++ team we’ve heard loud and clear from users that build times are a pain point. We’ve continued our focus on improving the step, linking, that dominates F5 build times. Fast F5 build times, or iteration build times, are a key contributor to developer productivity and we felt that there was a large opportunity so we narrowed in on changes that we felt could move the needle 2x or more.
April 4, 2019Apr 4, 201904/4/19The March 2019 update of the Visual Studio Code C/C++ extension is now available. This release includes many new features and bug fixes, including IntelliSense caching, Build and Debug Active File, and configuration squiggles. For a full list of this release’s improvements,
March 20, 2019Mar 20, 201903/20/19In Visual Studio 2019 Preview 2 we made the compiler back-end to prune away debug information that is unrelated to code or data emitted into binary and changed certain hash implementations in the PDB engine, to improve linker throughput, which resulted in more than 2x reduction on link time for some large AAA game title.

October 5, 2016Oct 5, 201610/5/16Continuing with our goal of further improving developer productivity with Visual Studio 2017 there have been major investments made for also improving incremental developer builds. The developer incremental build is one where a developer changes a single or multiple source files and builds.
October 5, 2016Oct 5, 201610/5/16The Visual C++ product has had projects ever since its inception. Visual C++ had its own IDE up through Visual Studio 6. Starting in Visual Studio .NET, C++ moved to a new IDE shared by Visual Basic, C#, C++, and other tools.

The virtualized OS, file system, environment settings, libraries, and other dependencies are all encapsulated and shipped as one image that can be shared between developers and machines. This is especially useful for C++ cross-platform developers because you can target a container that runs a different operating system than the one on your development machine.
