Hot Reload is now available to C++ developers when using the Visual Studio Debugger

For more details see the above link
IntelliCode

Whole line completions predict your next chunk of C# code based on your current context, and presents it as an inline suggestion to the right of your cursor.
Whole line completions are now compatible with the newest builds of JetBrains ReSharper. Note that updating the line completion context based on ReSharpers custom completions list item selection is not supported - if required, ReSharper users can opt to use Visual Studio native IntelliSense instead, as documented here

JavaScript/TypeScript

We have released a new JavaScript/TypeScript project type that builds standalone JavaScript/TypeScript projects with additional tooling. You will be able to create Angular and React projects in Visual Studio using the framework version installed on your computer.
JavaScript and TypeScript testing is now available in the Visual Studio Test Explorer
NPM GUI available, so you can now download NPM modules the same way you download Nuget packages

Remote Testing

Very early experimental preview of enabling running tests on remote environments such as linux containers, WSL, and over SSH connections.

Test tools support

Show in Test Explorer
New versions of the test platform starting with 17.0 will not be able to run Generic tests and Ordered tests. These specific features only shipped as part of an early version of MSTestv1 and are not included in MSTestv2. We see very low usage of these features and ordered tests is now considered contrary to best testing practices.
Some test experiences will not be available in 17.0 including creating new TestSettings files and the TestSettings editor. Test runs will still be able to use TestSettings files, however TestSettings was replaced with RunSettings and we encourage users to migrate improved performance and functionality. Read more.
Web Load Test and Coded UI Test support updates. Coded UI Tests and [Web Load Tests](Cloud-based load testing service end of life | Azure DevOps Blog (microsoft.com) were officially deprecated in 2019. To minimize impact to users there is minimum support for these features in Visual Studio 2022. We strongly encourage users to move off Coded UI Test and Web Load Test.

Toolbox population for UWP Extension SDKs

UWP Extension SDKs are now required to explicitly declare the types that they wish to appear in the Toolbox by listing them in their SdkManifest.xml file. The behavior of older versions of Visual Studio is unchanged; they will ignore the list of controls in the manifest and instead dynamically enumerate the control types in the SDK's assemblies.

Trusted Locations

We have revamped the “Trust Settings” functionality and can now show a warning whenever untrusted code (e.g. files, projects or folders) is about to be opened inside the IDE.
Trust checks are now done at the solution folder level
User created projects are automatically added to the trusted list
Users can skip trust checks on temporary locations created by Visual Studio

Updates, LTSC's and Deployment

With Visual Studio 2022, there will be multiple simultanouely supported servicing baselines that will release in the fall and in the spring. For more details, refer to Visual Studio Release Rhythm documentation and the Visual Studio 2022 Product Lifecycle.
The new installer that comes with Visual Studio 2022 now has the capability of configuring where the Visual Studio product should get its updates from. This allows you to choose updates from a different LTSC, or, if you're in a managed enterprise environment, you can configure the client to get its updates from a layout. The ability to configure the source for updates is new functionality that comes with the Visual Studio Installer, and thus the behavior is applicable to downlevel versions of Visual Studio too, such as Visual Studio 2019. For additional information about configuring the update channel, refer to the Update Visual Studio documentation. For additional information about making this work for network layouts, refer to the Visual Studio Administrators Guide.
IT Administrators can now report issues without having Visual Studio installed.

User Interface

The default icons have been updated and refreshed.

Web Tools

The Publish summary page now has actions to start / stop remote debugging and profiling under the '...' menu on the top right corner of the 'Hosting' section
The Connected Services page now has an action to launch Storage Explorer
The "ASP.NET Core Empty" template that comes with .NET 6 is using the new 'minimal APIs' paradigm for which we have started to add support
Azurite will be used for local emulation of Azure Storage instead of the older and no longer actively developed Azure Storage Emulator.
You can add authentication to your ASP.NET Core application using Microsoft identity platform through the Connected Services experience in Visual Studio.

WPF XAML Designer for .NET Framework

The current WPF XAML Designer for .NET Framework is replaced with a new WPF XAML Designer for .NET Framework, based on the same architecture used for the WPF XAML Designer for .NET (.NET Core). The Visual Studio experience will look the same, but third-party control vendors need to support the new extensibility model since the previous model based on .design.dll and Microsoft.Windows.Design.Extensibility is deprecated. If you already created a .designtools.dll extension for .NET (.NET Core), that same extension will work for the new WPF XAML Designer for .NET Framework. Please refer to the migration document below for further information about how to migrate to the new extensibility model.

XAML Hot Reload

XAML Hot Reload Changes - Minor changes to in-app toolbar and settings

XAML Live Preview

XAML Live Preview is now available for WPF, UWP, WinUI and Xamarin.Forms developers running their apps in either Android Emulator or as a UWP desktop app. Live Preview captures a running applications user interface and brings it into a docked window within Visual Studio. This makes it easier to use XAML Hot Reload to change the app while seeing those changes inside Visual Studio itself, without the need to tab back and forth between the running app and Visual Studio while making live XAML code changes.

For more information click on the link above.
XAML Sample Data

Design-Time Sample Data will now be added by default when creating DataGrid, ListBox, and ListView controls from the toolbox in WPF applications. To disable this behavior, uncheck ‘Automatically add sample data on element creation’ under Tools -> Options -> XAML Designer.”
To learn more about Sample Data , please visit the Sample Data documentation.

Improved XAML binding experience

We’ve made a bunch of improvements to make data binding fast and easy, such as quick access to the Data Binding dialog from Property Inspector, ability to set binding from Quick Actions, ability to choose the property to bind to inside the Data Binding Dialog.
