ASP.NET Visual Tools

Visual-first VS Code extension for ASP.NET Core (C#) — build, run, diagnose, and annotate without typing terminal commands.

Features

One-click Build & Run

• Status bar $(tools) Build ASP.NET — runs dotnet build /property:GenerateFullPaths=true, spins while building, then shows success or a clickable error count.
• Editor title bar (C# tabs) — $(tools) Build Current Project · $(play) Run / Watch.
• MSBuild output is parsed into the native Problems panel with red/yellow squiggles.

Error highlighting & actions

• Subtle red line tint + gutter alert icons on error lines.
• CodeLens above each diagnostic: Add Note · Explain Error · Google / StackOverflow.
• Hover cards with the same actions via command URIs.

Inline notes & ASP.NET Inspector

• Right-click → Add Note to this Line (suggestion chips + custom input).
• Ghost-text badges at end of line + bookmark gutter icons.
• Sidebar ASP.NET Inspector with Build Diagnostics and Code Notes & Bookmarks (inline Jump / Edit / Delete).
