Visual Studio 2019 Preview 2 is an exciting release for the C++ code analysis team. In this release, we shipped a new set of experimental rules that help you catch bugs in your codebase, namely: use-after-move and coroutine checks. This article provides an overview of the new rules and how you can enable them in your project.
Why re-write the preprocessor?
Recently, we published a blog post on C++ conformance completion. As mentioned in the blog post, the preprocessor in MSVC is currently getting an overhaul. We are doing this to improve its language conformance, address some of the longstanding bugs that were difficult to fix due to its design and improve its usability and diagnostics.
The Visual C++ team has been working to refresh our code analysis experience inside Visual Studio. We’re aiming to make these tools both more useful and natural to use and hope that they’ll benefit you no matter your workflow, style, or project type.

The “broken warnings theory” is a fictional theory of the norm-setting and signaling effect of coding practices and bug-checking techniques in 3rd party libraries on new bugs and design anti-patterns. The theory states that maintaining and monitoring warning levels to prevent small problems such as “signed/unsigned mismatch”,

Precompiled headers can reduce your compilation times significantly. They’ve worked reliably for millions of developers since they were introduced 25 years ago to speed up builds of MFC apps.

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.
The 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.
We 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.

One of the challenges with developing and maintaining cross-platform C++ code is dealing with different C++ compilers for different platforms. You write some code that builds fine with the Visual C++ compiler for your Windows-targeting build,
