BlazorMedCalculator

BlazorMedCalculator is a Blazor-based medical calculator web application built with ASP.NET.
It is intended as a demo and learning project, focusing on infrastructure concerns (authentication, email, PDF generation), rather than polished UI.

The application is under active development, and its functionality grows incrementally.

🎯 Project Goals

• Choose realistic Blazor backend architecture
• Apply clean separation between logic and infrastructure
• Solve practical problems (auth, email, PDF, content)
• Serve as a foundation for future modularization and expansion

🧱 Project Structure (Overview)

• Calculators – Core calculation logic
• Components – Blazor UI layer
• Endpoints – Application endpoints
• Interfaces – Service contracts
• Models – Domain and DTO models
• Services – Technical implementations (Email, PDF, Identity, Content)
• Data – Data layer (EF Core, migrations)

🛠️ Technologies Used

• ASP.NET / Blazor
• Entity Framework Core
• Microsoft SQL Server
• Markdig – Markdown processing
• QuestPDF – PDF generation
• ASP.NET Identity – Authentication and email flows

📧 Email Infrastructure (DEV / PROD Switch)

This project implements a real email infrastructure with a safe development mode. Real email sending can be disabled locally while preserving the full ASP.NET Identity email confirmation flow. Environment Switch (DEV vs PROD): Email behavior is controlled by a single configuration flag.

🔴 Production (appsettings.json): "Email": { "Enabled": true }

SmtpEmailService:

• Sends real emails with SMTP server
• SMTP options can be easily adjusted
• Used in Production

🟢 Development (appsettings.Development.json): "Email": { "Enabled": false }

FakeEmailService:

• Does not send emails
• Logs email content to application logs
• Used only in Development mode
