In this post I will briefly cover some of the most exciting updates included in the newest version of ReSharper and ReSharper C++. To learn more about our other .NET tools, including dotCover, dotMemory, dotPeek, and dotTrace, please check out this separate blog post<\/a>. <\/p>\n\n\n\n Before we dive into the feature set, we need to make an important announcement. Starting with the 2021.3 release, dupFinder will no longer be included in the ReSharper Command-Line Tools package. You can still use the dupFinder tool from previous releases. Learn more in the blog post<\/a>.<\/p><\/blockquote>\n\n\n\n Let\u2019s take a closer look!<\/p>\n\n\n\n ReSharper now supports the release build of the new Visual Studio 2022. You will have access to the same rich feature set you are already used to having in other Visual Studio versions. But since Visual Studio 2022 is an x64 process, there is no longer a limit to the maximum amount of memory that can be allocated to it. As a result, all ReSharper features work faster.<\/p>\n\n\n\n ReSharper continues to add more C# 10 features. Today, we are happy to add support for file-scoped namespaces, <\/em> Let\u2019s say you paste in some code with NRT syntax but you don\u2019t have NRTs enabled in your solution. There is now a quick-fix that gets rid of the NRT syntax for you. There are also several helpful new quick-fixes:<\/p>\n\n\n\n The latest version of C# isn\u2019t the only one getting support improvements. This release brings additional inspections and quick-fixes for general C# support, as well:<\/p>\n\n\n\n Additionally, scope quick-fixes and context actions are now executed in parallel and use the results of solution-wide analysis.<\/p>\n\n\n\n We\u2019ve added a few more gutter marks to help you quickly navigate through the inheritance structure of a class, interface, or struct. The new You can now call Find Usages <\/em>for user-defined implicit conversion operators. This allows you to find out whether user-defined implicit conversion operators are used at all and then navigate to blocks of code with conversions.<\/p>\n\n\n\n Finally, when you invoke Go to Type of Symbol<\/em> on a variable or parameter of an interface type in debug mode, ReSharper will take you to the exact implementation of it that is used in the current frame, rather than the interface declaration.<\/p>\n\n\n\n Here\u2019s just a sample of the highlights in the ReSharper C++ updates:<\/p>\n\n\n\n Check out this blog post<\/a> for details about all new features and improvements in ReSharper C++.<\/p>\n\n\n\n If you are eager to learn more about all these ReSharper features, please visit the What\u2019s New page<\/a>. <\/p>\n\n\n\n To learn more about our other .NET tools, including dotCover, dotMemory, dotPeek, and dotTrace, please check out this separate blog post<\/a>.<\/p>\n\n\n\n You can download the release build right now from the ReSharper 2021.3 page<\/a> or install it using the JetBrains Toolbox App<\/a>.
