C# Project Opener

Open the nearest .csproj as a solution in VS Code — no need to manually create or maintain .sln files.

How It Works

1. From any open file, the extension walks up the directory tree to find the nearest .csproj
2. If a fresh .sln file already exists (less than 24 hours old), it reuses it
3. Otherwise, it generates a new .sln using slngen
4. Opens the solution in C# Dev Kit for full IntelliSense, debugging, and project-aware features

Usage

1. Open any file inside a C# project
2. Run the command C#: Open Nearest Solution from the Command Palette (Ctrl+Shift+P)

Tip: Bind it to a keyboard shortcut for quick access.

Requirements

• slngen — the extension will prompt you to install it if not found:

  dotnet tool install --global Microsoft.VisualStudio.SlnGen.Tool
  

• C# Dev Kit (optional, for opening the solution directly)

Why?

Large C# codebases often don't have a single .sln that covers every project, and creating one manually is tedious. This extension lets you jump straight from any file to a working solution with full IDE support — just one command.

This extension was developed with AI assistance (Claude Opus 4.6).
