Ever spent hours explaining your codebase patterns to ChatGPT? Or wished GitHub Copilot understood your team's coding style? CodeContext.NET solves that.

This tool scans your C# project and creates a context file that tells AI assistants how your code works. No more explaining your patterns over and over.

New: Now detects and maps all your API endpoints automatically.

codecontext --path ./MyProject

That's it. You get a context file ready to paste into any AI chat.

Let's say you have this in your codebase:

private readonly IUserService _userService;

public async Task<Result<User>> GetUserAsync(int id)
{
    // your implementation
}

CodeContext detects:

• You use underscore for private fields
• Your async methods end with "Async"
• You prefer Result over exceptions
• All your API endpoints with routes and auth info

Next time you ask AI for help, it writes code YOUR way, not some generic tutorial style.

Install it:

dotnet tool install --global CodeContext.CLI

Run it:

codecontext

You'll get something like:

✓ Found 5 patterns
✓ Found 12 packages
✓ Context saved to: codebase-context.md

Here's what you actually get:

Private fields start with underscore (_)
Async methods end with 'Async' suffix
Use Result<T> pattern for error handling
Dependencies injected through constructor

API Endpoints:
- GET    /api/users          → GetAllUsers() [Authorize]
- POST   /api/users          → CreateUser(UserDto dto) [Admin]
- DELETE /api/users/{id}     → DeleteUser(int id) [Authorize]

Just copy this into ChatGPT/Claude/Copilot before asking for code.

Keep it simple:

codecontext                    # scan current folder
codecontext -p ../other-project  # scan different folder
codecontext -f json             # want JSON instead
codecontext -v                  # see what it's doing

Got tired of ChatGPT writing Java-style C# code. Wanted it to match my style without a 10-paragraph prompt every time.

Yeah, I totally outsourced the README to our robot overlords. Thanks for Gemini
