MY TOP 10 NEW VISUAL STUDIO FEATURES OF 2023 FOR .NET DEVELOPERS
James Montemagno
February 8th, 202418 9
Visual Studio 2022 saw an abundance of incredible features released in 2023,
which gave .NET developers a host of new tools to enhance their productivity.
With so many to choose from, I’ve hand-picked a selection that includes editor
improvements, productivity updates, and AI assistance. Let’s explore some of the
most impactful features that have become integral to my daily development
routine.
1. DEV TUNNELS
Dev Tunnels are a game-changer for developers who need to expose their local
development server to the internet. It provides a unique URL that directly
tunnels to your local machine. This feature is invaluable for scenarios like
mobile development where you need to test your backend on various devices and
have them all communicate with your local server seamlessly.
* Expose your Local Host development server with a unique URL.
* Useful for mobile development, allowing devices to connect to your local
machine.
2. HTTP FILES & ENDPOINT EXPLORER
HTTP files and Endpoint Explorer are a dynamic duo that supercharge API
development and testing within Visual Studio. Whenever you create a web API, it
adds an HTTP file where you can make requests and see real-time responses. This
is complemented by the Endpoint Explorer, which offers a visual representation
of all active endpoints in your app, allowing you to generate requests and
streamline your workflow.
* HTTP files let you interact with your web API using real-time requests and
responses.
* Endpoint Explorer provides a visual tool to see and interact with all API
endpoints.
3. GITHUB COPILOT & GITHUB COPILOT CHAT
GitHub Copilot and Copilot Chat have been amazing for developers seeking
AI-powered assistance. Copilot suggests code snippets while you type, using the
context of your application to offer relevant recommendations. Copilot Chat
allows you to communicate with the AI to get more detailed assistance on coding
challenges.
* GitHub Copilot provides code suggestions in real-time.
* Copilot Chat enables conversation with AI for coding help.

Released as a separate extension with subscripion you can easily install and
start your free trial to test it out today.
4. GIT & PR ENHANCEMENTS
Visual Studio 2022 has made significant strides with integrated Git features
simplifying the code commit and collaboration process. Developers can now
perform Git tasks such as branch creation, commits, and pull requests right from
the IDE, streamlining the process of code repository management.
* Create and manage Git repositories with integrated UI.
* Link commits to GitHub issues for better collaboration.
* Built-in pull request creation and review within Visual Studio.
5. BRACE COLORIZATION
This feature adds a splash of color to your code by differentiating brace pairs
with unique colors. This small but powerful feature can significantly improve
code readability by making it easier to visually match opening and closing
braces, especially in nested structures.
* Colors differentiate brace pairs at various nesting levels.
* Improves readability and aids in quickly identifying matching pairs.
6. SPELL CHECK
One of my most awaited editor improvements that came in Visual Studio 2023 is
the built-in spell checker. It is a handy tool that would have saved me from an
infamous typo I made early in my career, where I misspelled “shield” throughout
the entire source code for two years before it was caught. This spell checker
works similarly to those found in word processors like Word or Google Docs and
can be toggled on and off easily. Just look for the “ABC” icon with a check in
the toolbar.
HOW IT WORKS
* The spell checker detects misspelled words and underlines them with blue
squiggles.
* You can choose to ignore the suggestion, disable spell checking, or replace
the misspelled word with the correct one from the context menu.
* The spell checker is highly beneficial for maintaining accuracy in code
comments and string literals.
* Customizable by creating a custom dictionary of words to exclude in your
.editorconfig file.
7. ACCESSIBILITY CHECKER
Creating accessible applications is imperative, and Visual Studio’s new
Accessibility Checker makes this task much easier. This tool helps developers
identify and fix common accessibility issues within their apps, ensuring they’re
usable by everyone.
HOW IT WORKS
* Start debugging your WPF application and click on “Scan for accessibility
issues” to run the checker.
* The tool will highlight any accessibility errors, like null property names,
allowing you to fix them directly from the results.
.NET ASPIRE SUPPORT
Visual Studio 2023 introduces .NET Aspire orchestration, a preview feature that
simplifies cloud-native development. With the integration of .NET Aspire tools
inside Visual Studio, developers can quickly scaffold solutions that are
cloud-ready, integrating health checks, service discovery, and resiliency.
GETTING STARTED
* You can create a new .NET Aspire project from the templates provided
* Add Aspire components to existing projects.
* The template setups provide support for service defaults, tracing metrics,
and more.
9. UI REFRESH
The UI Refresh is an absolute delight to see, bringing subtle updates that
elevate the overall user experience. The refresh includes more modern UI
elements like floating tabs and rounded corner radii, along with new themes.
10. C# DEV KIT FOR VISUAL STUDIO CODE
C# Dev Kit borrows some familiar concepts from Visual Studio to bring a more
productive and reliable C# experience to VS Code. This approach ensures a great
experience whether you’re quickly editing a C# file, learning C#, or debugging a
backend API. The C# Dev Kit consists of a set of VS Code extensions that work
together to provide a rich C# editing experience, AI-powered development,
solution management, and integrated testing. As shown in the following graphic,
C# Dev Kit consists of:
* The C# extension, which provides base language services support and continues
to be maintained independent of this effort.
* C# Dev Kit extension, which builds from the foundations of Visual Studio to
provide solution management, templates, and test discovery/debugging.
* The IntelliCode for C# Dev Kit extension (optional), which brings AI-powered
development to the editor.

Yes I’ve been checking it for 1,5 years and it’s still broken. That’s why
I ask.

Do you have a specific issue? Saying broken doesn’t give a lot of
information… There are a lot of companies and developers around the
world building and shipping with .NET MAUI today, including myself.

Have you considered the (admittedly remote) possibility that Microsoft is
made up of a lot of different teams who work on a lot of different products
and that you’re asking this question on a blog entry completely unrelated
to MAUI? Just something to chew on before you make your next useless,
inflammatory blog comment.

I wrote that because James Montemagno is a large Xamarin and MAUI dev and
MAUI needs this programming capacity instead of shooting videos. I hope
you wrote that just because you don’t know much about MAUI.

No, you wrote that because you have no control over your impulses and
think that this is an appropriate place to vent your frustrations with
MAUI. The identity of the author is irrelevant; take your whining
somewhere else.

I didn’t know about the spell checker, this looks so useful! However it
doesn’t work for me – I enabled it via the “ABC” icon and nothing happened. I
even used the same typo as in your example (chekk), nothing gets underlined.
How do I diagnose what’s wrong?

What programming language is your code file using? The spell checker only
works for C#, C++ and Markdown at the moment. That could be the issue
you’re running into.

HTTP Endpoint and Explorer have the potential to become useful but honestly
right now it solves nothing that existing, mature tools don’t already do. I
tried using it (again) just the other day on an existing REST API as I added
new endpoints. I gave up after 30 minutes. Postman and/or HTTPREPL and/or
Powershell do everything it does and more. Here’s my shortlist of critical
features before it will remotely become an option:
– Must support applying default request headers to all requests (e.g. content
type, static auth)
– Must be able to get a response back and validate it. Otherwise this is just
manual testing whereas I can have automated testing in other tools.
– Need to be able to name requests in HTTP files. For remotely realistic APIs
it is too hard to understand otherwise.
– Explorer needs to be OpenAPI aware or otherwise be able to group and name
responses because just looking at a list of endpoints is too overwhelming.
– Need to be able to run all requests in HTTP and determine which fail.
I understand the VS Code version of this is more full featured and I’ve
considered using it but I assume the goal here is to keep us in VS so these
features are critical within VS. If I need to switch to VS Code to do this
then there is no benefit from moving away from my other (non-VS) tools that I
have now.

GitHub Copilot & GitHub Copilot Chat is not part of Visual Studio. It is an
add on with a separate pricing and licensing. It is like saying ReSharper is
a top 10 new feature.

Extensions and ecosystem around Visual Studio to me are part of what is new
just as if other extensions launched that changed how you code. That’s how
I look at it, but get where you are coming from.
