A live, editable map of your .NET solution, one click from your code: projects, dependency injection, HTTP endpoints, and the path each request takes down to the database. It updates while you type.
Sightline: Open the map (or the Sightline button in the status bar) opens the map of the solution in your browser, or in a VS Code tab.
Show in Sightline (right-click in a C# file, or Ctrl+Alt+M / Cmd+Alt+M) shows the method, endpoint or class under the cursor on the map: an endpoint or method as the flow of what it calls, a class with everything around it.
Problems panel: while a map is open, Sightline's findings show there too: a singleton that holds a scoped service, a service that is asked for but never registered, circular dependencies, and the layer rules of your sightline.json.
The extension uses a map that is already open for the folder, whether you started it with dotnet sightline or it runs beside your app through the Co.Revington.Sightline.Hosting package. Otherwise it starts one: the repository's own tool when sightline init set it up, or dnx Co.Revington.Sightline.
Needs
The .NET 10 SDK, and a folder you trust: reading a solution runs MSBuild and restores packages, which runs code from the repository, so the extension stays off in Restricted Mode.

How to start Sightline, for example sightline for a global install. User settings only: a repository's .vscode/settings.json cannot set it.
