Las Vegas Sessions You Can Watch Now](https://devblogs.microsoft.com/visualstudio/from-ai-to-net-20-vs-live-las-vegas-sessions-you-can-watch-now/) ![Image 8](https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2022/11/IMG_1377-96x96.jpg) Jim Harrer Starting in **Visual Studio 18.5**, you can create and build Visual Studio extensions (VSIX) using an officially supported SDK-style project. This brings VSIX projects into the modern build and deployment pipeline, improving incremental build performance and making the build → deploy → debug workflow more reliable. Install the **Visual Studio extension development** workload to get the templates and tooling**and try it out for yourself!** **Note:** Extensions written using the modern VisualStudio.Extensibility framework already supports SDK-style projects today. This update extends the same SDK-style experience to **VSSDK-based** Visual Studio extensions. ### What We Are Adding:Copy link * Official SDK-style support for projects that produce VSSDK-based extensions. * Build time reductions of up to 75%! We’ve added end-to-end incremental build support including [Fast Up To Date Check](https://github.com/dotnet/project-system/blob/main/docs/up-to-date-check.md) and up to date deployment logic. Through internal adoption, we see a reduction of up to 75% in build time in large solutions for small changes or changes confined to a single sub project. * Updated in-box templates: SDK-style by default, with the familiar project items (tool windows, classifiers, commands, etc.). ### Project Usage Copy link Creating a project is done the same way you are used to, using the “VSIX Project” or “Empty VSIX Project” template: [![Image 9: new vsix project template image](https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/04/new-vsix-project-template.webp)](https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/04/new-vsix-project-template.webp) This will yield a much more compact csproj than before: only 20 lines: Copy ```xml net472 enable 14 true true true ``` ## Does it impact my extension?Copy link * If you create a new extension, you will automatically get full SDK-Style support. * Your existing MPF style extension will continue to work should you choose not to migrate. This update adds an _official_ SDK-style option; it doesn’t force a conversion. * You can update your project to an SDK-style project file to take advantage of these features. * Vsixmanifest files included in SDK-style projects now open by default in the XML editor. The old designer is still available through the ‘Open With’ menu. ## Migration In Brief Copy link * I migrated an extension from Mads Kristensen as an example: [Convert to SDK-style project by matthew-j-clark · Pull Request #6 · madskristensen/SelectedWhitespace · GitHub](https://github.com/madskristensen/SelectedWhitespace/pull/6/files) * If you have any XAML, you need to add: `true`to your csproj. * You must mark your extension as deployable in your SLN or SLNX file if you want it to deploy when you hit F5. * You can do this in your SLNX like this: Copy ```xml       ``` * When available, you can do this in the project configuration: [![Image 10: configuration manager image](https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/04/configuration-manager.webp)](https://devblogs.microsoft.com/visualstudio/wp-content/uploads/sites/4/2026/04/configuration-manager.webp) * `true` will setup most sensible defaults for you and reduce the size of your csproj. This will setup options like `CreateVsixContainer` as true, and the legacy `DeployExtension` to false. * `true` Should be added to your csproj if you will add it to other solution files to ensure the deploy checkbox is set automatically. ## Agentic conversion Copy link We’re experimenting with ways of making this as easy as possible for you. To that end, we’ve added an agent skill to the [vs-agent-plugins](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.upgradeassistant) repository you can use in conjunction with the Modernize agent. Let us know whether this workflow is helpful, or if you have a different agentic workflow in mind for extension development.
