Visual Studio 2019 version 16.1 Preview 3
The third Preview version of Visual Studio 2019 version 16.1 is now available. You can download it from VisualStudio.com. Or, if you’re already on the Preview channel, just click the notification bell from inside your Visual Studio 2019 Preview installation to update. This latest preview contains a range of additions, including IntelliCode support by default, various C++ productivity enhancements, and .NET tooling updates. We’ve highlighted some notable features below, and you can see a list of all the changes in the Preview release notes.
In Preview 3, you are now able to use your local Windows Subsystem for Linux (WSL) installation with C++ natively in Visual Studio without additional configuration or any SSH connections. In addition, AddressSanitizer is integrated directly into Visual Studio for WSL and Linux projects.
This release also provides the ability to separate your remote build machine from your remote debug machine in both MSBuild and CMake projects. Learn more about the new Linux features in the Visual Studio 2019 version 16.1 Preview 3 Linux roll-up post.
Quick Info tooltips, which appear when hovering over a method name, now offer you a link that will search for online docs to learn more about the relevant code construct. For red-squiggled code, the link provided by Quick Info will search for the error online. You will now also see colorized code in these tooltips to reflect their colorization in the editor. Learn more about quick info tooltip improvements in Preview 3 in the quick info improvements post on the C++ Team Blog.
Two new C++ Code Analysis quick fixes are available: C6001: using uninitialized memory <variable> and C26494 VAR_USE_BEFORE_INIT. These quick fixes are available via the lightbulb menu on relevant lines and enabled by default in the Microsoft Native Minimum ruleset and C++ Core Check Type rulesets, respectively.
You can now experience experimental IntelliSense completion for unimported types. IntelliSense suggestions for types in dependencies will be provided in your project even if you have not yet added the import statement to your file. You can toggle this option on/off by navigating to Tools > Options > Text Editor > C# > IntelliSense.
You can now use a new EditorConfig code style rule to require or prevent using directives inside a namespace. This setting will also be exported when you use the “Generate .editorconfig” button located in Tools > Options > Text Editor > C# > Code Style.
