# AppxManifest IntelliSense for Windows Development

**[DevBlogs](https://daily.dev/sources/devblogs)** · 5 min read · 14 upvotes · 1 comments

## Summary

Microsoft released v0.3.0 of the WinApp VS Code extension, adding schema-aware IntelliSense for AppxManifest.xml files, including autocomplete, hover documentation, diagnostics, and Go to Definition. The update also adds workspace search for file/folder picking in packaging, running, and signing commands, plus new commands, UX improvements like post-package notifications and architecture mismatch warnings, and several reliability fixes to the debug adapter and launch configuration handling. The extension remains in public preview and requires Windows 10+, VS Code 1.109.0+, and a matching debugger extension.

## Questions this post answers

### What new features does version 0.3.0 of the WinApp VS Code extension add for editing AppxManifest.xml files?

Version 0.3.0 adds schema-aware IntelliSense for AppxManifest.xml and .appxmanifest files, bundling the AppxManifest XSD schemas from the Windows SDK. It provides element, attribute, and value autocompletion, hover documentation, inline diagnostics for missing required fields and invalid values, and Go to Definition support via F12 or Ctrl+Click. IntelliSense is enabled by default once the extension is installed.

### What are the requirements for running the WinApp VS Code extension?

The WinApp VS Code extension requires Windows 10 or later, Visual Studio Code version 1.109.0 or later, and, for debugging, the appropriate debugger extension matching the app's language such as C#, C/C++, or the built-in Node.js debugger. It is currently distributed as a public preview through the Visual Studio Code Marketplace.

> Does the visual editor round-trip comments, namespace order, and unknown extension elements without changing an existing AppxManifest?
