Visual Studio 2022 Preview release notes
We're excited to announce the availability of Visual Studio 2022 v17.12. This update focuses on providing fantastic developer experiences for working with .NET 9 projects and new AI productivity features, along with continuous improvements all-around.
Features
All the new features in the latest preview release.
Productivity
Copy from the Error List 📣
Copying an error from the Error List now copies just the description instead of the entire row to the clipboard.
You see an error in the Error List that you don't know how to fix. So, you select it and hit Ctrl+C to copy the description for a web search. After you've pasted it into the search engine, you realize it copied all column headers and row values instead of just the description. Now you must delete everything except the error description before you can perform the web search. This is cumbersome, but now we have a fix!
When you copy an error from the Error List using Ctrl+C, only the description is copied to the clipboard. This makes it easier to search for the error online or share it with others.
You can still copy the entire row by right-clicking the error and selecting Copy Row from the context menu or hitting Ctrl+Shift+C.
If what you wanted to do with the error description was to do a web search, then just hit Ctrl+F1 to search for information about the error online.
📣 See feature ticket to share your feedback and continue the conversation.
Go to line anywhere in Code Search 📣
In Code Search, you can now navigate to a specific line in the current document or other specified document.
Sometimes you know that there's an issue on a certain line in your code and you want to get to it quickly. Maybe you were told about an error being thrown on line 43 of some file, or you want to get to the bottom of a specific file.
Code Search now supports quick navigation to a specific line in your code.
Open Code Search and go to a line in the current document by using colon + line number. For example,
:39will navigate to line 39 in the active file.
You can also go to a line in a different document by using file name + colon + line number. For example,
Order:43will navigate to line 43 in Order.cs. If you don't specify the exact file name, then the search will try to find the best match.
📣 See feature ticket to share your feedback and continue the conversation.
Dock the Code Search window 📣
You can now freely position the Code Search window with capabilities like docking and auto-hiding.
If you need Code or Feature Search to stay out of your way, you now have more control over the behavior of the search window.
You can now dock the search window and perform tool window actions with it, like Solution Explorer and others.
After opening Code Search or Feature Search, click on the box icon at the top right to convert it into a tool window. You may choose to dock it elsewhere, pop it out, auto-hide, etc. You can revert to the dismissible window by closing the tool window and reopening search.
We've also simplified and cleaned up the previewing experience in search. There is now one button, indicated with an eye icon, to toggle the preview on and off.
The position of the preview panel will also adjust based on the dimensions of the search window.
📣 See feature ticket to share your feedback and continue the conversation.
Customize collapsed text indicator 📣
Set custom colors for the collapsed text indicator in the Visual Studio editor.
You can now customize your editor experience even further with new options for customizing the collapsed text indicator:
To try it out and set custom foreground and background colors for each, navigate to Tools > Options > Environment > Fonts and Colors.
There, you'll find two new items for customization:
- Collapsed Text Indicator (Collapsed)
- Collapsed Text Indicator (Expanded)
You can set the colors for the collapsed and expanded indicators independently from one another using predefined colors or custom colors of your choosing.
📣 See feature ticket to share your feedback and continue the conversation.
Refresh your Find results 📣
You can now refresh the results to a previous Find to get up-to-date search matches.
We heard from a lot of users that it's frustrating having to reopen the Find window and go through the motions of redoing a search to get updated results. Maybe you just refactored some code and want to confirm everything has been changed as expected, or you pulled some recent changes and need your recent Find operation to reflect those updates.
After completing Find in Files, you will now have the option to Refresh the Find results in the window. You'll get your updated results without having to redo the search.
We've also redesigned the former Repeat Find option to distinguish it from Refresh. It is now represented as Modify Find with a pencil icon. This button will still reopen Find in Files with the same search criteria you used for that results window.
📣 See feature ticket to share your feedback and continue the conversation.
More space for horizontal scrollbar 📣
You can now control the visibility of the file level indicators in CodeLens.
The area with the horizontal scrollbar can get pretty cluttered up in Visual Studio. We're helping make it easier to clean it up by turning off the file level indicators in CodeLens by default.
If you do want the option on, you can find the Show file level CodeLens indicator option under Tools > Options > Text Editor > Advanced. This option affects visibility for file types that have the file level CodeLens control in the bottom editor margin such as XAML, HTML, and CSS, and does not affect files that contain inline CodeLens.
📣 See feature ticket to share your feedback and continue the conversation.
Non-blocking Code Cleanup on save
When Code Cleanup is run on Save, it now operates in a non-blocking manner, for a smoother coding experience.
Previously when a Code Cleanup is run on Save, you can't perform any actions in the IDE. We've now enhanced this to operate in a non-blocking manner.
The cleanup process will run in the background and can be automatically canceled if you resume typing, ensuring a smoother and more responsive coding experience.

Better AI completions for C#
GitHub Copilot brings in additional context from relevant source files to improve completions for C#.
GitHub Copilot code completions provide autocomplete suggestions inline as you code. These suggestions are generated based on the content from your currently active file and any other open files in your editor. However, we have discovered that incorporating more relevant context significantly improves these suggestions.
To enhance the experience for C# developers, we've updated GitHub Copilot to include additional C# context, such as available types and methods in completions.
With the latest version of Visual Studio, GitHub Copilot now automatically considers semantically relevant files for additional context, even if these files are not open in your editor. This improvement helps reduce hallucinations while offering more relevant and accurate suggestions.

Copy Git link 📣
You can get a GitHub or Azure DevOps link to a specific line of code to make it easy to share with your colleagues.
Whenever you share a few lines of code with a colleague, it can often be useful for them to get extra context from your repository. However, if they're working on something else it can take too long and disrupt their work to checkout your branch.
Now, you can highlight the code you want to share in your editor, open the context menu with a right click, and under the Git submenu get a shareable link to your code in GitHub or Azure DevOps. This makes it simple and easy to collaborate, and it smooths the flow between the IDE and your remote repos on the web.

MotW security warnings
Mark of the web (MotW) security warnings are now integrated into the overall trust functionality.
Visual Studio will show a security warning when it detects that you're attempting to open content tagged with the Mark of the Web (MotW) identifier.
This new trust-related warning conveys the risks of opening content from potentially unsafe sources like internet downloads.
You can modify the default trust experience by going to the Trust Settings under Tools > Options > Environment.
Preserve font across theme changes 📣
Changing themes will now remember your font and font size preferences.
We understand that the fonts developers select when coding is a personal choice, influenced by preferences for readability, accessibility, or aesthetics. Visual Studio themes primarily focus on presentation colors and are independent of your preferred fonts.
With this update, we've introduced functionality to retain your font face and size choices when switching themes. You can now set your font preferences once and switch themes in Visual Studio without needing to reconfigure your font settings every time. Note that the colors of your fonts remain linked to the theme, as that is the purpose of themes, but your font selections will be preserved.
This feature will be enabled by default for all users. If you prefer the previous behavior, go to Tools > Manage Preview Features and find the option Separate font settings from color theme selection. If this option is checked, your font preferences will be maintained regardless of theme changes. Uncheck the box to reinstate the previous behavior which ties font choices to theme.

Azure App Service publish security updates
Publishing to Azure App Service securely using integrated security updates.
Azure App Service's publishing guidance advises customers to disable Basic Authentication and enable publishing via integrated authentication.
The new feature in Visual Studio 2022 disables Basic Authentication and enables integrated security for publishing to Azure App Service. This ensures that publishing credentials is handled securely, reducing the risks associated with Basic Authentication.
When publishing to an Azure App Service that has Basic Authentication enabled (which is not recommended), users will see the Turn on Basic Authentication option, and it will be unchecked by default. Customers who need to retain Basic Authentication can check the box, but given the recommendation is to disable Basic Authentication, this is unchecked by default. So you start secure if this is the first time you publish or, you get secure once you go through the publishing process after you update Visual Studio.
If you've created the Web App recently via the portal or this or any future version of Visual Studio, Basic Authentication will be disabled by default. For any Web App that's already got Basic Authentication disabled, we circumvent inadvertently making the Web App less secure by disabling the checkbox altogether, so you stay secure.
Azure WebJobs Linux support 📣
Publishing to Azure WebJobs on Linux is now supported by right-click publish in Visual Studio.
Cross-platform .NET 5.0+ Console Apps are supported on Azure WebJobs Linux, and now, you can right-click publish your code to Azure WebJobs on Linux from Visual Studio, too!
📣 See feature ticket to share your feedback and continue the conversation.
Azure Functions Flex Consumption
Publish to Azure Flex Consumption hosting plan, currently in Preview.
If you're trying the new Azure Functions Flex Consumption hosting plan, currently in Preview, you'll enjoy being able to right-click publish to Flex from Visual Studio.
Flex Consumption will further extend your apps' functionality and provide you the following:
- Virtual Network integration at no extra cost
- Fast and predictable scaling with instance size choice and per instance concurrency control
- Serverless with scale to zero and you only pay for instances while they are active
- Cold Start mitigation with the optional Always Ready instances feature
Learn more about Flex Consumption in the announcement blog post or documentation and try out one of our samples.
Connected Services security update
Making your apps and development experienced more secure.
In this update to Connected Services, you can now connect your project code to Azure resources, like Azure Storage, without the need for secrets or connection strings in your code or configuration.
Now, you'll give your connection a name, the endpoints are persisted to configuration instead of the full connection string. This means fewer secrets on disk, so your development time will be more secure by default and suffer fewer errors committing secrets to source control.
We're also using the latest Azure SDKs, so you'll get support for connecting to your Azure resources using your Visual Studio (or Azure CLI) login instead of connecting via a connection string. When running locally, your code will use your logged-in credential to access the resources. When running in Azure, the Azure SDK will use the managed identity of the app service to access the resources.
Connected Services sets it all up for you and injects the appropriate code to use integrated identity instead of secrets. During publishing, your app will be configured with the appropriate identity and roles required to access the resources.

Enhanced WinUI components search
Enhance WinUI project setup with improved Visual Studio Installer search, simplifying component location for developers.
Streamline your WinUI project setup further with our latest Visual Studio installer update! Developers can now quickly locate WinUI-related components, eliminating the previous frustration of navigating through an empty search result. This enhancement simplifies the development environment configuration, allowing for a more intuitive and efficient user experience.
Open the Visual Studio Installer, go to Individual components tab and search for WinUI related keywords (WinUI, WinRT)!
.NET 9 SDK support for UWP 📣
Visual Studio now includes the .NET 9 SDK with UWP support out of the box.
One of the necessary steps to take to try out UWP on .NET 9 in the initial preview was to install a nightly build of the .NET 9 SDK. With this new release of Visual Studio, that is no longer needed.
Visual Studio now includes the .NET 9 SDK, which has all the new support for UWP on .NET 9 (specifically, logic to reference the UWP XAML projections, and to configure CsWinRT to project types for UWP XAML apps). You can now build and run UWP on .NET 9 projects with the .NET SDK that's automatically installed with Visual Studio.
📣 See feature ticket to share your feedback and continue the conversation.
Simplified .csproj for UWP 📣
UseUwpTools is now set automatically by Visual Studio for modern UWP projects on .NET 9.
UWP apps and libraries using .NET 9 used to require two properties in their .csproj files:
UseUwp, which configures the .NET SDK for UWP XAML apps, andUseUwpTools, which enables all the new tooling in Visual Studio to build and run UWP XAML apps.The
UseUwpToolsproperty is now automatically set by Visual Studio whenUseUwpis set, to make the .csproj less verbose in the common scenario. For advanced scenarios, it is still possible to opt-out by manually disablingUseUwpTools.📣 See feature ticket to share your feedback and continue the conversation.
RIDs for UWP in .NET 9 fixed 📣
UWP on .NET 9 class libraries correctly set the RIDs to the right values for Native AOT.
We fixed a bug in the APPX tooling for UWP class libraries (and WinRT components) on .NET 9, which was applying the runtime identifiers of UWP on .NET Native by default (ie. using the
win10-prefix, and including platforms which are no longer supported, such as arm).The APPX tools will now set the right RIDs for .NET 9 projects by default:
win-x86;win-x64;win-arm64. It is still possible to manually specify these, if desired.📣 See feature ticket to share your feedback and continue the conversation.
UWP project creation fixed 📣
We fixed the Universal Template Wizard that was causing to not longer show an error dialog when creating new UWP on .NET 9 projects.
If you're using the preview VSIX with the new project templates for UWP on .NET 9, you might have noticed that an error dialog was showing up right when creating a new project. This was especially problematic when creating a new solution, as Visual Studio would not open it correctly after creating the project. This issue has now been resolved, and creating new projects targeting UWP on .NET 9 will now work correctly.
📣 See feature ticket to share your feedback and continue the conversation.
Web
Request variables in HTTP files 📣
HTTP files now support request variables. That is where you can send a request and then use data from the response, or request, in future requests.
When working with HTTP files, a common scenario is calling an endpoint, taking a value from the response, and sending in a subsequent request. For example, you may call an endpoint to authenticate a user and then on later calls you can pass the token that was returned from the login endpoint. Prior to this release this was not possible in Visual Studio. In the snippet below you can see an example of how this works in an HTTP file.
# @name login POST {{TodoApi_HostAddress}}/users/token Content-Type: application/json { "username": "{{myusername}}", "password": "{{mypassword}}" } ### GET {{TodoApi_HostAddress}}/todos Authorization: Bearer {{login.response.body.$.token}} ###In the above snippet there are two requests, the first calling into the
/users/tokenendpoint to authenticate the user. Immediately above the request line, you'll see the comment# @name login. This syntax gives the request a name (loginin this case) and configures it as a Request Variable. When the request is sent you can access values from the response, or request, in any future request that is sent from that HTTP file. Since this is a request to login, you should be careful to secure your secrets. In Visual Studio we have support for accessing secrets in a secure manner. See this section on the docs for more info on handling secrets.The second request calls into an authenticated endpoint,
/todos, which will return thetodoitems for that user. In the request the token is passed in as a header with the line.Authorization: Bearer {{login.response.body.$.token}}The
/users/tokenendpoint returns a response in JSON. The token is extracted with a JSON Path expression,$.token, on the body of the response. If you are using an endpoint that returns XML, instead of a JSON Path expression you can pass in an XPath expression. The support in Visual Studio has been inspired by the existing OSS extension for REST Client that is available for Visual Studio Code. You can learn more about Request Variables there. We will be adding documentation soon to discuss this support in much more detail.📣 See feature ticket to share your feedback and continue the conversation.
Vitest support in JavaScript and TypeScript 📣
When using JavaScript and TypeScript projects you can now author test cases with Vitest.
In JavaScript and TypeScript projects (JSTS), projects that have the extension .esproj, we have added support to discover and run tests authored with Vitest. To get started with Vitest tests, in a JSTS project add the vitest package using the npm in the Solution Explorer and then modify the project file to have the following properties declared.
<JavaScriptTestRoot>test\</JavaScriptTestRoot> <JavaScriptTestFramework>Vitest</JavaScriptTestFramework>Ensure that the value for
JavaScriptTestRoothas the correct relative path to where your test files are located.Add your tests to the correct folder and build the project/solution. After that, you should see the test cases in the Test Explorer.
In the Test Explorer you can see the different test cases that are discovered and execute the test cases.
We have not yet added support for debugging, but we will be adding that support soon. Another known issue is when you double click on a test case in Test Explorer, it will take you to the first line of the file where the test case is defined. We will be improving this experience as well.
📣 See feature ticket to share your feedback and continue the conversation.
Inlay Hints for more languages 📣
Inlay Hint support has been added to JavaScript, TypeScript, Python and Razor as well as a setting to control its behavior.
Inlay hints show additional information about source code that is rendered inline. This is usually used to show inferred types, parameter names, and other implicit information from your code directly in your editor.
We have added support to show Inlay Hints in JavaScript, TypeScript, Razor, and Python. We have also added a new setting so that you can customize the behavior of hints across these languages. This setting doesn't apply to C# and C++ yet. To enable Inlay Hints for these languages you can use the new setting at Tools > Options > Text Editor > All Languages > Inlay Hints. You can see the new option in the following image.
There are three different values for Inlay Hints.
- Always: Always show the Inlay Hints.
- While Pressing Alt+F1: Only shows Inlay Hints while Alt and F1 are pressed. This is the default value.
- Never: Inlay Hints are never shown.
For JavaScript and TypeScript, there is an additional options page to configure the behavior of Inlay Hints. This can be found at Tools > Options > Text Editor > JavaScript/TypeScript > Advanced > General.
Those options are shown in the image that follows.
By default, all these options are disabled, you should enable the hints that you are interested in viewing for JavaScript and TypeScript files. In a future update we may change the default values for these options. In the image below you can see a JavaScript file that shows Inlay Hints.
In the previous image the Inlay Hints that are shown are the gray boxes with
: numberto indicate the type of the variable.📣 See feature ticket to share your feedback and continue the conversation.
HTTP files shared environment 📣
In HTTP environment files we have added support to share variables across environments.
When using HTTP files in Visual Studio you can define environments so that you can create different settings for API testing. Previously, sharing a variable across these environments wasn't possible. We have added support for a new entry,
$shared, in the environment file which enables you define default values for variables which are available across all environments.For example, consider the environment file (http-client.env.json) below.
{ "$shared": { "HostAddress": "https://localhost:7293" }, "dev": { "username": "sayedha" }, "dev2": { "username": "madsk" }, "staging": { "username": "staginuser", "HostAddress": "https://sayedrest.example.com" } }We have defined the shared values in
$sharedabove which consists of theHostAddressvariable which is set tolocalhost:7293.Of the three environments defined, neither dev environment has specified the value for
HostAddressbut staging has a value for it.When you use either the
devordev2environment the value forHostAddresswill come from$sharedsince those environments don't have a value forHostAddress. When using the staging environment, the value forHostAddresswill be set tohttps://sayedrest.example.com.📣 See feature ticket to share your feedback and continue the conversation.
Data
SDK-style SQL projects in SSDT 📣
You can now use the SDK-style project file format in your SQL Server Data Tools projects.
This update adds SQL projects based on the Microsoft.Build.Sql SDK, which brings cross-platform support and improved package references to SQL Server Data Tools (SSDT) projects. With less verbose project files and database references to NuGet packages, teams can more efficiently collaborate on large databases in a single project or compile multiple sets of objects from several projects.
Database deployments from a Microsoft.Build.Sql project can be automated in Windows and Linux environments where the Microsoft.SqlPackage dotnet tool publishes the build artifact (.dacpac) from the SQL project. Learn more about the preview of SDK-style SQL projects and DevOps for SQL.
The Microsoft.Build.Sql project SDK is open source and developed on GitHub.
Make sure to install the latest SSDT preview component in the Visual Studio installer to use the SDK-style SQL projects in your solution.

NuGet audits transitive packages 📣
NuGet is changing default audit settings to include transitive packages.
NuGet Audit, first added in Visual Studio 17.8 (and .NET 8), provides warnings during restore if any packages used by your project have known vulnerabilities.
For more information on NuGet Audit, including all configuration options, see the documentation on NuGet Audit.
In this release, NuGet Audit defaults for NuGetAuditMode have changed. Previously, only direct package references were being reported by default (
<NuGetAuditMode>direct</NuGetAuditMode>). Now, by default it will warn on both direct and transitive packages (<NuGetAuditMode>all</NuGetAuditMode>) with known vulnerabilities. To retain the previous defaults, you can explicitly set your preferred value of NuGetAuditMode in your project or Directory.Build.props file.Alternatively, you can set SdkAnalysisLevel to a version number lower than 9.0.100 but be aware this will affect all features that use SdkAnalysisLevel.
NuGet Audit requires a package source that provides a vulnerability database. NuGet.org provides vulnerabilities from the GitHub Advisories Database.
Starting with Visual Studio 17.12, it's now possible to specify audit sources in NuGet.Config files, so it's no longer required to use nuget.org as a package source.
If you're not using nuget.org as a package source and wish to use NuGet Audit for vulnerable package reporting during restore, add the following to a NuGet.Config file in your solution directory:
<confiuration> <!-- any existing config, including <packageSources> --> <auditSources> <add key="nuget.org" value="https://api.nuget.org/v3/index.json" /> </auditSources> </configuration>📣 See feature ticket to share your feedback and continue the conversation.
C++
Set C++ Command Line Arguments
A new way to set your command line arguments right from the toolbar.
Quickly set your command line arguments for your C++ project with the new Set Arguments toolbar item. This combo box allows you to set your command line arguments right from the toolbar, so you can quickly change your arguments. When you run your project, any arguments entered in the box will be passed.
This toolbar component will show up by default if you have Game development with C++ workload installed. If you don't see it, you can add it by right-clicking on the toolbar and selecting Set Arguments.
Note: This feature is currently available for Unreal Engine projects only. General C++ projects will be supported in future releases.
Build Insights view explanations
Learn how to use each tab of Build Insights via a newly added link to documentation.
You can now see a short description on how each tab of Build Insights can be used, along with a link to the documentation for a detailed explanation.
Build Insights path adjustments
Get a clearer view of your file in Build Insights, see full path on hover.
We have hidden full and relative paths to reduce clutter. To see full paths, simply hover over the file. You will also see a new File Name column for both files and Translation Units, displayed by default to help you quickly identify files without parsing lengthy paths.
Open Folder for Unreal Engine uproject
A new way of opening your uproject.
We have added an additional entry point to open your Unreal Engine uproject with Visual Studio's uproject support. You can now open your uproject directly from the File menu by selecting Open > Folder.... This will open your Unreal Engine project in Visual Studio.
For more information on how to use this feature, see Directly Editing .uproject in Visual Studio.
Change signature improved
You can now effectively change signatures with our improved feature for C++.
We have made enhancements to the Change Signature feature for C++. The user interface has been updated, allowing you to manage parameters by adding, removing, and rearranging them in the top box. You can also change their order through a drag-and-drop interface.
The access methods remain the same: press Ctrl+. to trigger the Quick Actions and Refactorings menu and select Change Signature.
