Language support for .akbura and .akcss files in Visual Studio.
Expression bindings (${x.bind ...}) use shared Workspaces and Roslyn-projected
C# completion, hover, navigation, classification and diagnostics. The built-in
prefix has a separate completion item and retains safe ${...} commit boundaries.
Syntactic highlighting and prefix completion work before project loading; C#
semantic features need a loaded project. Shared references/rename semantics are
also available through LSP; a native Visual Studio Rename UI adapter is not yet
implemented. Native snapshot translation, pairing and Undo must be verified in
an experimental Visual Studio instance in addition to component-level tests.
Features
syntax highlighting and classification;
completion and completion commit behavior;
diagnostics and suggested actions;
native Akbura Component item template for Add New Item and Quick Add;
quick info and navigation;
outlining and smart indentation;
syntax-aware automatic pairing and markup editing.
Requirements
Visual Studio 2026 version 18.9 or later (Roslyn 5.9 or later);
Community, Professional, or Enterprise edition;
64-bit Visual Studio.
Visual Studio 2022 is not supported: it supplies Roslyn 4.14, while Akbura
requires host Roslyn 5.9. The manifest targets the stable VSSDK API 17.14 for
Marketplace compatibility; its separate CoreEditor prerequisite still requires
Visual Studio 2026 18.9 or later.
The extension keeps its stable VSIX identity so installed copies receive future
updates from the same Marketplace listing.
What's new in 12.0.4.19
Open Akbura documents now refresh semantic diagnostics automatically when their project or a referenced project changes, including during project initialization and dependency restoration.
Preserved unsaved Akbura, AKCSS, and resource text when synchronizing project context.
Prevented obsolete background analysis from replacing current editor diagnostics and Error List entries.
What's new in 12.0.4.18
Corrected the Marketplace API target while preserving the Visual Studio 2026 host requirement.
What's new in 12.0.4.17
Reduced compiler and shared workspace allocations through pooling, symbol and metadata caches, and streaming symbol names.
Updated Roslyn to 5.9.0 and preserved event-hook completion for incomplete lambdas.
Requires Visual Studio 2026 version 18.9 or later.
What's new in 12.0.4.6
Added completion for state hooks and improved declaration-name completion.
Preserved valid completion candidates while semantic snapshots update.
Fixed markup type discovery and sibling project-reference resolution.
Added support for non-generic collection parameter sources.
Fixed automatic closing of braces when an opening brace is typed on a new line.
What's new in 12.0.4.5
Stabilized ${Binding ...} completion while semantic snapshots lag behind typing.
Prevented $if and $foreach suggestions from appearing inside binding extensions.
Rejects stale completion commits after the editor snapshot changes.

Added editor support for reactive $foreach markup.
Added $foreach syntax classification and highlighting.
Improved language services for foreach variables, @index, navigation, rename, completion, and formatting.
Included the latest workspace and parser fixes.
What's new in 12.0.4.2
Fixed incremental parsing while typing utilities such as w-30, so completed values no longer retain a stale Identifier expected diagnostic.
Added regression coverage for utility prefixes, numeric continuations, replacements, and deletions.
What's new in 12.0.4.1
Added the native Akbura Component item template for Add New Item and Quick Add.
