## Development Workflow
### Git Workflow
main ────────────────────────────────────────────────────────► │ │ └── feature/ABC-123-add-user-auth ─────────┘ │ │ │ ▼ ▼ ▼ commit commit commit
**Branch Naming:**
- `feature/TICKET-description` - New features
- `fix/TICKET-description` - Bug fixes
- `chore/description` - Maintenance tasks
**Commit Messages:**
type(scope): description
feat(auth): add OAuth2 support for Azure AD fix(api): resolve null reference in user service docs(readme): update installation instructions
### Code Review Process
1. Create feature branch from `main`
2. Make changes with meaningful commits
3. Push and create pull request
4. Request review from team member
5. Address feedback
6. Merge when approved (squash merge)
### Testing Requirements
- All new code must have tests
- Minimum 80% code coverage for new features
- Integration tests for API endpoints
- E2E tests for critical user flows
Run all tests
dotnet test
Run with coverage
dotnet test --collect:"XPlat Code Coverage"
Run specific test project
dotnet test tests/Unit/
---
## Common Tasks
### Adding a New API Endpoint
1. Create feature folder in `src/Api/Features/`
2. Add request/response models
3. Implement endpoint handler
4. Add validation
5. Write tests
6. Update OpenAPI documentation
**Example:**
// src/Api/Features/Users/GetUser.cs public static class GetUser { public sealed record Response(Guid Id, string Name, string Email);
public static void Map(IEndpointRouteBuilder app) => app.MapGet("/api/users/{id:guid}", HandleAsync) .WithName("GetUser") .WithTags("Users") .Produces<Response>() .ProducesProblem(StatusCodes.Status404NotFound);
private static async Task<IResult> HandleAsync( Guid id, IUserRepository repository, CancellationToken ct) { var user = await repository.GetByIdAsync(id, ct); return user is null ? Results.NotFound() : Results.Ok(new Response(user.Id, user.Name, user.Email)); } }
### Running Database Migrations
Add a new migration
dotnet ef migrations add AddUserTable -p src/Api -s src/Api
Apply migrations
dotnet ef database update -p src/Api -s src/Api
Generate SQL script
dotnet ef migrations script -p src/Api -s src/Api -o migration.sql
### Debugging
**VS Code:**
1. Set breakpoint (F9)
2. Start debugging (F5)
3. Use debug console for evaluation
**Rider:**
1. Set breakpoint
2. Debug (Shift+F9)
3. Use Evaluate Expression
**Logging:**
_logger.LogInformation("Processing request {RequestId}", requestId); _logger.LogError(exception, "Failed to process {RequestId}", requestId);

|---|---|
| Progressive | Start simple, increase complexity |
| Practical | Focus on doing, not just reading |
| Current | Keep up-to-date with system changes |
| Accessible | Easy to find and navigate |
| Feedback-driven | Iterate based on new hire input |
Anti-Patterns to Avoid
- Overwhelming Day 1 with too much information
- Assuming prior knowledge without verification
- Outdated setup instructions
- No checkpoint/verification steps
- Missing "getting help" information
Workflow
When creating onboarding docs:
- Audit Current State: What exists? What's outdated?
- Interview Recent Hires: What was confusing? Missing?
- Define Learning Goals: What should they know at each stage?
- Create Progressive Content: Day 1 → Week 1 → Month 1
- Add Verification Steps: How do they know they succeeded?
- Test with Real User: Have someone follow the guide
- Iterate: Update based on feedback
