Windows 10: Announcing general availability of Visual Studio IntelliCode

Brink · May 6, 2019

We’re excited to announce the general availability of Visual Studio IntelliCode and offer a sneak peek at an up-and-coming feature we think you’ll love! With the release of Visual Studio 2019 Version 16.1, IntelliCode will be included with any workload supporting C#, C++, TypeScript/JavaScript, and XAML. However, only the C# and XAML models are currently generally available. C++ and TypeScript/JavaScript remain in preview at this time. We’ve learned so much from all of you in during our year in public preview and are thrilled for this next step.

If you haven’t heard of IntelliCode, it’s a set of AI-assisted capabilities that aims to improve developer productivity with features like contextual IntelliSense, code formatting and style rule inference.

General Availability with Preview Perks

IntelliCode is growing fast so we’ve also packed in some preview features you can try out if you’d like, no extra installations required. Preview features, such as such as C++ and TypeScript/JavaScript support and argument completion, will be disabled by default but you can easily enable any preview features via Tools > Options > IntelliCode. Check out our updated docs for a full list of preview features.

A Quick PEEK: finding repeated edits

Have you ever found yourself making a repeated edit in your code, for instance when you’re refactoring to introduce a new helper function? You might consider creating a regular expression search to find all the places in your code where the change is required – but that seems like a lot of work, so you resign yourself to the tedious and error prone task of going through the code manually. What if an algorithm could track your edits (locally of course), and learn when you were doing something repetitive like that after only a couple of examples? Repeated edit detection does just that, and suggests other places where you need that same change:

This feature is under development right now, and we’re looking to make it available in a future release of IntelliCode.

Let us know what you think!

IntelliCode has benefitted greatly from all the customer feedback we’ve received in the past year and we hope you’ll help us continue to improve by letting us know how IntelliCode is working for you! Feel free to let us know what you’d like to see next by filing feature requests or reporting issues via Developer Community.

Try it out in Visual Studio now!

Introducing Visual Studio IntelliCode

Visual Studio IntelliCode brings you the next generation of developer productivity by providing AI-assisted development. Every keystroke and every review is informed by best practices and tailored to your code context. You can try it out today by downloading the experimental extension for Visual Studio 2017 that provides AI-powered IntelliSense.

What is IntelliCode?

IntelliCode is a set of AI-assisted capabilities that improve developer productivity with features like contextual IntelliSense, inference and enforcement for code styles, and focused reviews for your pull requests (PRs.) Check out the video to see what we demoed at BUILD 2018 – it shows you just some of the capabilities that IntelliCode will offer.

AI-assisted IntelliSense, and the other features shown at BUILD 2018, are just the start. Over time you’ll see more ways that we’ll assist your end-to-end developer workflow.

What can IntelliCode do now?

As you type, AI-assisted IntelliSense recommends the most likely API. This makes it easier to learn a new API and dramatically reduces the number of keystrokes required to complete a line. With more context from the code you write, IntelliSense becomes more accurate.

IntelliCode’s improvements are not just about statement completion. IntelliCode also provides guidance as to the most appropriate overload for that API given the current code context. No more extraneous scrolling!

AI-assisted IntelliSense: better recommendations with every keystroke

How does it work?

IntelliCode generates recommendations by using a machine-learning model that is trained on thousands of public codebases – today it uses over 2000 GitHub repos that each have more than 100 stars to ensure that you’re benefiting from best practices. The model is used in your IDE along with your local code context to provide .NET related APIs that are likely to be the most relevant for you given the line of code you’re writing. We’ll be growing and improving the model over time so the recommendations will get better as we progress.

While it’s still very early, you can download and experiment with this capability in the IntelliCode extension right away. We welcome your feedback.

What’s next?

Beyond what is currently in our experimental extension, here are a few of the things IntelliCode is experimenting with. Right now, the extension is only C#, but we want to expand to other languages later.

Automatic definition of styles and formatting: no more style inconsistencies

Consistency is important for maintainability; in fact recent research shows that 18% of PR comments are related to coding conventions, styles and naming issues.

IntelliCode can automatically generate an .editorconfig file that best matches your current styles and formatting. Once generated, this file will help you maintain consistency in your code. Fixing up formatting issues is a snap with existing lightbulbs or with a new, code-cleanup command.

Assisting with every review

As developers, you know that code reviews can be time consuming. It’s challenging to focus on the right things when other issues get in the way. IntelliCode makes reviews less painful for everyone by providing focus for the reviewer, and an automated, first-level review.

Find misused variables

With automatic generation of comments in files for potential issues, you’ll be able to identify and fix issues faster. For example, IntelliCode can detect variable misuse, often introduced through copy/paste where a variable is of the correct type but used in the wrong context. These analyses go beyond style concerns or what a conventional static analysis tool can find – it can find actual bugs in your code. It’s discovered bugs in our code too!

Get recommendations for files to review

IntelliCode focuses your reviews by indicating which files may need extra attention. These recommendations are based on machine-learning heuristics for the history of the files, their dependencies, the code complexity and history. These capabilities can be applied alongside CI analysis services and other code review processes. The results can be surface in the IDE and in web-based tools. For example, review comments generated by the IntelliCode analyzers can appear in your online Visual Studio Team Services’ pull requests (PRs).

Some of IntelliCode’s analyzers use machine-learning on public codebases, and are then specialized to your own repository. When these analyses become available, they will require a sign-up and registration process.

Why IntelliCode?

Millions of repos of code are now available in the public domain. This code represents a tremendous amount of knowledge that can be accessed at your fingertips, tailored to your context.
Microsoft is investing extensively in machine-learning and AI technologies. We’re working with Microsoft Research to leverage the latest techniques to learn from source code and deliver new, innovative ways to enhance the coding life of developers, so that you can deliver your software with greater confidence and velocity.

Get Involved

We are excited to give you an early glimpse into IntelliCode, which is currently optimized for C#. Although we are sharing some of it today in an IDE extension (download) you can try right away, today’s demo is just a hint into what’s coming soon.

As we expand the capabilities to more scenarios and other languages, we’ll announce a limited preview of IntelliCode. If you want to learn more, keep up with the project, and be invited to the private preview please sign up!

Happy Coding!

Visual Studio IntelliCode supports more languages and learns from code

At Build 2018, we announced Visual Studio IntelliCode, a set of AI-assisted capabilities that improve developer productivity. IntelliCode includes features like contextual IntelliSense code completion recommendations, code formatting, and style rule inference.

IntelliCode has just received some major updates that make its context-sensitive AI-assisted IntelliSense recommendations even better. You can download the updated IntelliCode Extension for Visual Studio and IntelliCode Extension for Visual Studio Code today! The Visual Studio extension already works with the newly-release Visual Studio 2019 Preview 1.

AI-assisted IntelliSense recommendations based on your language of choice

Many of you have requested IntelliCode recommendations for your favorite languages. With this update, we’re excited to add four more languages to the list that can get AI-assisted IntelliSense recommendations. In our extension for Visual Studio, C++ and XAML now get IntelliCode alongside existing support for C#. In our extension for Visual Studio Code, TypeScript/JavaScript and Java are added alongside existing support for Python.

We’ll be sharing more details about IntelliCode’s support for each language on their respective blogs [C++ | TypeScript and JavaScript | Java]

AI-assisted IntelliSense for C# with recommendations based on your own code

Until now, IntelliCode’s recommendations have been based on learning patterns from thousands of open source GitHub repos. But what if you’re using code that isn’t in that set of repos? Perhaps you use a lot of internal utility and base class libraries, or domain-specific libraries that aren’t commonly used in open source code, and would like to see IntelliCode recommendations for them too? If you’re using C#, you can now have IntelliCode learn patterns and make recommendations based on your own code!

When you open Visual Studio after installing the updated IntelliCode Extension for Visual Studio, you’ll see a prompt that lets you know about training on your code, and will direct you to the brand new IntelliCode page to get started. You can also find the new page under View > Other Windows > IntelliCode. Once training is done, we’ll let you know about the top classes we found usage for, so you can just open a C# file and start typing to try out the new recommendations. We keep the trained models secured, so only you and those who have been given your model’s sharing link can access them–so your model and what it’s learned about your code stay private to you. See our FAQ for more details.

Check out Allison’s video below to see how this new feature works.

Visual Studio 2019 now generally available

Visual Studio 2019 is generally available today and available for download. With Visual Studio 2019, you and your teams will become more productive in building current and future projects as you benefit from the innovation in the IDE that makes every keystroke count.

As we’ve shared earlier, Visual Studio 2019 improves on Visual Studio 2017 in a few areas. It helps you get into your code more quickly by making it simpler to clone a Git repo or to open an existing project or folder. It also introduces improvements to the template selection screen to make it easier to start a new project. While you’re coding, you’ll notice that Visual Studio 2019 improves code navigation and adds many refactorings, as well as a document health indicator and one-click code clean-up to apply multiple refactoring rules. There are also improvements to the debugging experience, including data breakpoints for .NET Core apps that help you break only on value changes you’re looking for. It also includes get AI-assisted code completion with Visual Studio IntelliCode.

These capabilities work with both your existing project and new projects – from cross-platform C++ applications, to .NET mobile apps for Android and iOS written using Xamarin, to cloud-native applications using Azure services. The goal with Visual Studio 2019 is to support these projects from development, through testing, debugging, and even deployment, all while minimizing the need for you to switch between different applications, portals, and websites.

Check out the launch event

Be sure to tune in to the Visual Studio 2019 Launch Event today at launch.visualstudio.com, or watch it on-demand later, where we’ll go into a lot more depth on these features and many others. During the launch event, we’ll discuss and demo Visual Studio 2019. We’ll also share content on Visual Studio 2019 for Mac and Visual Studio Live Share, both of which are also releasing today. There are also almost 70 local launch events around the world you can join today and over 200 between now and end of June. Thank you for your enthusiasm about our best release yet.
