Register GoToHandlerAction as a keyboard-assignable VS/ReSharper command with Alt+H default

[Copilot]

Alt+H was intercepted by VS's Help menu and GoToHandlerAction was invisible in Tools > Options > Environment > Keyboard because no VS/ReSharper command was ever registered — only a Rider plugin.xml shortcut existed, which has no effect in Visual Studio.

Changes

• New GoToHandlerNavigationAction — implements IExecutableAction decorated with [Action]:

  [Action("GoToHandlerAction", "Go to Handler",
      ShortcutScope = ShortcutScope.TextEditor,
      DefaultShortcutText = "Alt+H")]
  public class GoToHandlerNavigationAction : IExecutableAction

  • Update(): enables only when the cursor is on a supported MediatR/Mediator request identifier
  • Execute(): delegates to HandlerSelector.NavigateToHandler() — same logic as the existing context-menu and navigate-from-here paths
• .gitignore: added .nuget/ to exclude tooling binaries

Yes. The root cause was that the plugin had no registered VS/ReSharper command for "Go to Handler" at all.

The keyboard shortcut in plugin.xml (<keyboard-shortcut keymap="$default" first-keystroke="alt H" />) only applies to Rider/IntelliJ — it is completely ignored by Visual Studio. For VS/ReSharper, an action must be registered as a .NET class that:

1. Implements IExecutableAction
2. Is decorated with [Action(...)] (which registers it with the ReSharper action system and makes it visible in VS Tools > Options > Environment > Keyboard)

The plugin had GoToHandlerAction (a ContextActionBase) for the right-click lightbulb menu and MediatorRequestNavigateFromHereProvider (a INavigateFromHereProvider) for the Navigate-from-here menu, but nothing that VS could bind a keyboard shortcut to.

The fix adds GoToHandlerNavigationAction which is the missing piece — an IExecutableAction with [Action("GoToHandlerAction", "Go to Handler", ShortcutScope = ShortcutScope.TextEditor, DefaultShortcutText = "Alt+H")]. This makes the action appear in the VS keyboard settings dialog under the name GoToHandlerAction with Alt+H pre-configured as the default.
