## Overview

This repository contains a blood-pressure calculator in ASP.NET Core and a Python/Flask port. In each, a browser submits readings to the page handler, which validates input and presents a result; the Python implementation explicitly calculates a category and provides advice, while the sampled .NET domain model leaves category calculation unimplemented. The graph includes both runtime paths and Python’s optional Application Insights telemetry. Source excerpts show wiring for the Python app and .NET startup, but not the page templates or the full .NET result-rendering path.

Main entry points: [`BPCalculator_Python/app.py`](https://github.com/pso25/softwaredelivery_bp_ca1/blob/master/BPCalculator_Python/app.py) (Flask App), [`BPCalculator_Python/pages.py`](https://github.com/pso25/softwaredelivery_bp_ca1/blob/master/BPCalculator_Python/pages.py) (Page Routes), [`BPCalculator/Program.cs`](https://github.com/pso25/softwaredelivery_bp_ca1/blob/master/BPCalculator/Program.cs) (Web Host), [`BPCalculator/Startup.cs`](https://github.com/pso25/softwaredelivery_bp_ca1/blob/master/BPCalculator/Startup.cs) (Razor Pipeline)
