+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Visual Studio extension that adds a right-click context menu command to open solution files, project files, or individual files in Notepad++. It targets .NET Framework 4.8 and uses the VS SDK.
+
+## Build Commands
+
+Build the extension (requires Visual Studio with VS SDK or .NET Framework 4.8 targeting pack):
+```
+msbuild src\CodingWithCalvin.OpenInNotepadPlusPlus.sln
+```
+
+Debug by pressing F5 in Visual Studio - this launches the VS Experimental Instance (`/rootsuffix Exp`).
+
+## Architecture
+
+The extension has a simple structure:
+
+- **OpenInNotepadPlusPlusPackage.cs** - The VS package entry point, registers the command and settings page
+- **Commands/OpenExecutableCommand.cs** - Handles the context menu command, gets the selected path and launches Notepad++
+- **Helpers/ProjectHelpers.cs** - Resolves file paths from Solution Explorer selection (handles solutions, projects, project items, and unloaded projects)
+- **Dialogs/SettingsDialogPage.cs** - Options page for configuring the Notepad++ executable path
+- **VSCommandTable.vsct** - Defines the context menu command placement
+
+## Key Implementation Details
+
+Path resolution in `ProjectHelpers.GetSelectedPath()` handles three selection types:
+1. `ProjectItem` - uses `FileNames[1]`
+2. `Project` - uses `FullName` with fallback to `UniqueName` for unloaded projects
+3. `Solution` - uses `FullName`
+
+The extension auto-detects Notepad++ in the default install location but allows custom paths via Tools > Options.
+
+## Development Requirements
+
+Install the [Extensibility Essentials 2022](https://marketplace.visualstudio.com/items?itemName=MadsKristensen.ExtensibilityEssentials2022) extension for Visual Studio.
