HTML is rendered using Chromium Embedded Framework v75.
How it works

Static .html pages and associated resources (images, styles, scripts) are loaded by the embedded Chromium browser directly from the disk. For the live preview, page content is provided from a memory buffer.
To show preview for dynamic pages, you need to start the web application (usually pressing Ctrl + F5). HTML 11 finds App/Project URL in web server settings (usually http://localhost:[random-port]), adds the file path to it and opens the preview. When you change and save a page, Visual Studio recompiles it on save, updates the application on the fly, HTML 11 updates the preview and you see the updated page.

If a page preview is not displayed, you can enable diagnostics in Options:

It will have a refreshed set of icons, more personalization options, and support to provide you more control over building modern applications. Continue reading to know more about Visual Studio 2022, its release schedule, and the first public preview build.
What's new coming with Visual Studio 2022
Microsoft announces some details about the next major release of Visual Studio.

Microsoft said that it will include updated icons for better clarity, legibility, and contrast. It will also use a new fixed-width font (Cascadia Code) for better readability and ligature support
New IDE means new personalization settings. Visual Studio 2022 will provide you more abilities to customize aspects of the IDE to sync the settings across devices. If you are using multiple dev boxes, you will be beneficial from that.
Visual Studio 2022 will have full support for .NET 6. So, you can build multi-platform apps (Windows, Android, macOS, and iOS) using the .NET Multi-platform App UI (.NET MAUI).
It will also help you to quickly build modern, cloud-based applications with Azure. Apart from these, Visual Studio 2022 will also include performance improvements while running diagnostics and debuggers. It will make a good real-time collaboration using the Live Share. If you are using Git or GitHub, Visual Studio 2022 will have the full support and improved code search.
