However the immense recognition of the Visible Studio Code programmer’s editor, the Visible Studio IDE remains to be on the coronary heart of Microsoft’s growth toolchain technique. Greater than 25 years of evolution have introduced us a customizable growth atmosphere that goes a great distance past the unique widespread UI for a set of growth instruments.
At the moment Visible Studio is a single software that dynamically hundreds the instruments and languages wanted to construct your undertaking. You’ll be able to preconfigure toolchains, in addition to choose and blend the options that assist you to ship code. The consequence is a versatile growth atmosphere that helps fashionable growth fashions, together with distant growth and shared code. There’s even assist for the most recent AI-powered coding assistants.
Key to that flexibility is Visible Studio’s extension mannequin. It lets you construct your personal instruments that hook into the Visible Studio atmosphere, utilizing hooks within the UI and a built-in language server so as to add your personal code highlighting and completion options. On the coronary heart of this mannequin is a toolkit that helps you recover from the hurdles in extension growth, with templates, API wrappers, and devoted instruments.
That extension mannequin is altering. In 2021 I checked out how Visible Studio 2022 added assist for 64-bit extensions, however there’s much more happening than supporting a bigger deal with area. There’s extra to be finished to port current extensions to the brand new atmosphere, however porting progress has been good, and it must be attainable to reassemble your common toolchain in 64-bit type, prepared for Visible Studio 2022.
Introducing VisualStudio.Extensibility
The most important modifications to Visible Studio extensions are coming with a very new extension mannequin, now renamed VisualStudio.Extensibility. It modifications the way in which extension code interacts with Visible Studio and reduces the chance of an extension crashing or hanging your IDE. It does this by permitting extensions to run exterior the Visible Studio course of, so if one crashes or pauses, it is not going to have an effect on the host IDE.
Introducing a brand new extension mannequin has allowed the Visible Studio staff to ship a number of essential enhancements. A brand new set of APIs has been refactored and redesigned to be less complicated. Sadly for builders who used C++ to construct extensions, the brand new mannequin is .NET solely. This transformation offers some benefits: New variations of an extension could be hot-loaded so you possibly can replace with out restarting your total growth atmosphere. They’re cross-platform and can run on the upcoming Arm launch of Visible Studio with none rework. Utilizing separate processes for extensions will finally let you select a belief stage in a future Visible Studio launch, for instance, locking down file system entry and limiting API calls to solely these provided by Visible Studio.
Microsoft is taking a phased method to rolling out this new extension mannequin. The primary part, with assist for out-of-process extensions to be used with open paperwork, shipped in September 2021. The second part has now arrived, almost a yr later. It gained’t be the final, both; full compatibility with the older extension mannequin shouldn’t be anticipated till after the subsequent main launch of Visible Studio. Such a sluggish route could seem odd, however it is sensible as Visible Studio is such an essential a part of the Microsoft ecosystem that any points, irrespective of how small, might find yourself inflicting important issues for a lot of builders. Much better to be secure than sorry.
The primary part took benefit of out-of-process operation to host extensions that analyze and parse code, working with what could be fairly massive doc timber. That may be memory-intensive, and by operating in its personal course of, an extension could be managed by Home windows’ personal schedulers, defending Visible Studio. For instance, you could possibly write a linter that hundreds your present doc window contents, parses them, and delivers outcomes with out affecting the primary Visible Studio course of. A whole lot of code being scanned might have locked your edit window. As a substitute, the scan now runs in a separate course of whilst you proceed to work, staying in stream and in focus.
Part 2: Including UIs to extensions
The second part of the brand new extensibility mannequin launched not too long ago, taking the out-of-process mannequin a lot additional with assist for a distant UI framework. This makes use of the acquainted model-view-viewmodel sample on the coronary heart of a lot of recent .NET’s UI instruments. In case you’ve constructed a MAUI app or related, you need to discover the method utilized by Visible Studio extensions a lot the identical. Extension home windows could be created inside Visible Studio, positioned instantly by your code, or positioned mechanically by Visible Studio.
Home windows created by this methodology are a versatile instrument; they are often toggled on and off as wanted with an asynchronous connection to Visible Studio. Extension home windows are an essential a part of including your personal instruments to Microsoft’s IDE. You’ll be able to visualize actions or add an uncomplicated method of selecting new parts on your code. For instance, should you’re writing an extension to shortly generate XAML layouts for desktop functions, you could possibly generate a window that holds a catalog of attainable layouts, which can be utilized as a picker that mechanically hundreds a code scaffolding into your software, able to be personalized.
Including UI to Visible Studio could be highly effective, and easy extension choices shortly add as much as productiveness beneficial properties. A few of the Part 2 choices let you add tooltips to your extensions whereas others add progress notifications to long-running exterior instructions. This final possibility is beneficial for extensions that combine Visible Studio into devops workflows, so you possibly can see how an exterior job or take a look at is operating. These progress notifications assist when working with asynchronous operations in extensions, guaranteeing that your customers don’t give up actions earlier than they’re accomplished.
There are some important variations between this method and conventional Home windows Presentation Basis growth. Maybe an important factor to notice is that you could’t use your personal controls. You should utilize solely Distant UI’s personal set. That is to assist Visible Studio’s themes, as you don’t need your extension to conflict with the remainder of the applying. Theme assist could be added by importing type assets from the Visible Studio shell to type your extension.
One other helpful characteristic in Part 2 is assist for in-process APIs. This permits an extension to work with older APIs if you’re both porting an older extension to the brand new mannequin otherwise you wish to combine older and newer capabilities in the identical code. This will add threat, however it’s a great way to get your extension into the Visible Studio market whilst you await future phases so as to add APIs and options you want.
Though this isn’t an open-source undertaking, documentation is being developed and delivered on GitHub. Alongside the documentation, Microsoft has delivered a set of undertaking templates and instruments for testing and debugging your personal extensions by means of the Visible Studio Market, prepared to be used. This could offer you all the pieces you must begin constructing your personal out-of-process extensions for Visible Studio. The consequence must be a extra secure growth platform for everybody.
