A2v10 Xaml Language Service

IntelliSense for the .vxaml dialect of the A2v10 platform — the XAML-flavoured markup behind A2v10 application UI (not WPF .xaml or Avalonia .axaml).

What you get

Completion — element tags, attribute names, attribute values (enums / booleans) and markup-extension types and arguments, drawn from the real types your files reference and filtered by the content model.
Syntax colouring — tag names, attribute names, values, markup extensions, comments and CDATA.
On-type formatting — matching close tags, self-close completion and auto-closing pairs.
Diagnostics — unterminated values, mismatched tags and malformed markup extensions, reported as you type.

Setup

Put the assemblies your .vxaml files reference (e.g. A2v10.Xaml.dll) into a folder named @assemblies somewhere above them. The extension walks up the directory tree to find it — no project or package configuration required.

MyProject/
├── @assemblies/
│   └── A2v10.Xaml.dll
└── Views/
    └── Index.vxaml

Restart Visual Studio after installing; .vxaml files are then recognised automatically.
