For a more comprehensive summary of new C++ features in Visual Studio 17.8, see [What’s New for C++ Developers in Visual Studio 2022 17.8](https://devblogs.microsoft.com/cppblog/whats-new-for-cpp-developers-in-visual-studio-2022-17-8).\

For a summary of new features in the Visual Studio 17.8 IDE, see [Visual Studio 2022 version 17.8 Release Notes](/visualstudio/releases/2022/release-notes).

Briefly, some of the new features are:

* C++ structured diagnostics in the Output window and a new problem details window that provides more information about the error. For more information, see [Structured SARIF Output](../build/reference/sarif-output.md) and [Problem Details Window](/visualstudio/ide/reference/problem-details-window).

* A feature that lets you visualize the size and alignment of your classes, structs, unions, base types, or enums even before the code is compiled. Hover over the identifier and a Quick Info displays the size and alignment information.

* A feature that suggests when to mark member functions `const` because they don’t modify the object’s state. Hover over a member function and click the light bulb icon to mark the function as `const`.

* Visual Studio now prompts you to mark global functions as static via a screwdriver icon that will appear by the function name. Click the screwdriver icon to mark the function as static.

* Unused #include directives are dimmed in the editor. You can hover over a dimmed include and use the light bulb menu to either remove that include or all unused includes. You can also add `#include` directives for entities that are currently indirectly included via other headers. For more information, see [Clean up C/C++ includes in Visual Studio](../ide/include-cleanup-overview.md).

* More Unreal Engine support:

* Unreal Engine Test Adapter lets you discover, run, manage, and debug your Unreal Engine tests without leaving the Visual Studio IDE.

* With Unreal Engine Code Snippets, you can find common Unreal Engine constructs as snippets in your member list.

* Build Insights is now integrated with Visual Studio 2022 and works with MSBuild and CMake projects using MSVC. You can now see additional information about the compilation of a function such as how long it took to compile and the number of ForceInlines.

* Remote Linux unit test support now lets you run your CTest and GTest tests on your remote Linux machines from Visual Studio’s Test Explorer, just like your local tests.
