Similar to the spell checker in other programs, Visual Studio will highlight any suspicious errors and display a context menu as the user resolves them, or you can use Alt+Enter to bring up the menu. From the menu, the user can use the word replacement types from the various dictionaries that have been enabled, ignore suggestions or disable the spell checker.

If the user is editing a C++ or C# document and accepts a spelling change for an identifier, the tool will also perform a refactoring of the code to update all other instances of the identifier so that the code is written without throwing any errors the next time it tries to compile. When ignoring suggestions is selected, Visual Studio will create the exclusion.dic file in the AppData directory and add the word, and then Visual Studio will continue to ignore the word in all Visual Studio instances so the spell checker does not become annoying.

Find and replace in Visual Studio 2022 17.4 files is now 3-4 times faster compared to version 17.3. Microsoft says this was achieved through incremental improvements such as asynchronous saving and maximizing caching and indexing. Microsoft test data shows that Visual Studio 2022 17.3 has a 25-second replacement operation, compared to 8 seconds in 17.4.

In addition, C++ project indexing is now faster. Users will notice a 25-30% performance improvement when populating source code indexes in large C++ projects.

Similarly, the need to reload solutions during branch switching has been reduced by 80%. Compared to Visual Studio 2019, branch switching takes 16 seconds for version 17.3 and about 10 seconds for Visual Studio 2022 version 17.4.

NET configuration switch responsiveness performance improvements are also shown in the following table.

In terms of unit testing, Test Explorer can surface the entire project test much faster. In Microsoft testing, performance was improved by a factor of 1 over the previous version when tested on 150 projects and 300,000 test solutions. Likewise, test components run 3x faster and test runner process connections are established faster.

Finally, most save operations have been moved to a background thread so that the IDE remains responsive and unaffected by the save process. Microsoft says this improvement will be most noticeable on slow drives, large projects, and network shares.

Visual Studio for Mac 17.4 toolbar now has a new Restart button (round arrow icon) that users can click on while debugging. With the return of the Class tools window, users can now once again drag and drop documents into the side-by-side editor or drag them out into the floating window. The new UI in the editor provides an improved experience for users.

In addition, users can install Visual Studio for Mac without first enabling Rosetta; however, in some cases, Rosetta is still required and a prompt will appear if it is not already enabled. NET MAUI applications.

Users can download Visual Studio for Mac v17.4 preview version 2.1 from a dedicated page.

In addition, extension developers can now publish Arm64 extensions and amd64 (64-bit) versions of extensions on a single Marketplace entry.

In June of this year, Microsoft Visual Studio 2022 supported Arm64 for the first time, allowing developers to develop Arm64 applications natively on ARM devices.

In addition, Visual Studio 2022 also supports Apple’s Apple Silicon (Arm64) processor, opening large solutions and other operations 50% faster than Visual Studio 2019 for Mac.

NET MAUI is out of Preview and is now available in the Visual Studio 2022 Release Channel on Windows. This support includes productivity features that help users quickly build and publish NET client applications to Android, iOS, macOS, and Windows from a single codebase. Hot Reload, Live Visual Tree, and XAML Live Preview are some of the tools that can increase productivity.

Microsoft has also added the Teams Toolkit to Visual Studio, which helps users create applications for Teams. To create a Teams Command Bot that responds to chat commands, you can use the Teams Toolkit, which automatically configures the Bot Framework. if users want to get started with the toolkit, Microsoft has created a demo on how to use the toolkit to create a notification bot.

This update also introduces low-priority builds for C++, where developers can limit the CPU power of compiled code. It also introduces a new static analysis check for std::optional to help write safer code. Microsoft says it has been working to improve C++ performance. Visual Studio now has about a 2X improvement in its ability to index and color C++ code compared to previous versions of Visual Studio.
