## Overview

Windows-specific MSVC C++ toolkit for Zed. Provides automatic detection and configuration of MSVC toolchain, Windows SDK, and clangd for C/C++ CMake projects.

## Key Features

- **MSVC Environment Detection**: Auto-detects Visual Studio 2022+, MSVC v143+, and Windows SDK
- **Automatic .clangd Generation**: Creates proper MSVC include paths for clangd
- **Compile Database Detection**: Finds `compile_commands.json` for accurate code analysis
- **CMake Language Support**: Integrates neocmakelsp for CMakeLists.txt support
- **CMake Tasks**: Auto-generates `.zed/tasks.json` with configure, build, and run tasks

## Differentiation

This extension is specifically designed for **Windows + MSVC environments**. Unlike generic C++/CMake extensions, it:

1. Automatically detects Windows-specific paths (MSVC, Windows SDK via vswhere.exe)
2. Generates MSVC-compatible `.clangd` configuration
3. Works seamlessly with Visual Studio installation layouts

The CMake LSP functionality (neocmakelsp) is included because Windows C++ developers typically work with CMake projects, and having both MSVC toolchain detection AND CMake support in one extension provides a cohesive experience.

Notes for Reviewers

Why CMake Support Included?

Windows C++ development with MSVC almost always involves CMake. Rather than requiring users to install two separate extensions:

1. neocmake - for CMake LSP
2. Another extension - for MSVC toolchain detection

This extension provides both in a cohesive package specifically for Windows developers.

No Conflict with neocmake

Users who prefer the standalone neocmake extension can still use it. This extension does not conflict - it simply provides an all-in-one solution for Windows MSVC C++ development.
