.NET Platform & ToolsStart Here

Note: Install the environment, understand the platform before writing any C# syntax.

Build: Setup - Visual Studio, Git, GitHub, dotnet CLI, first Console App

>What is .NET >CLR, CTS, CLS, IL >dotnet CLI >Project Types & NuGet >Visual Studio >Git - Version Control >GitHub >Assemblies & Namespaces

Start Stage 01 ->GitHub

C# Fundamentals

Note: Master the language. Every pattern here is used in every stage after this.

Build: Student Report Card Generator - Console App

>Variables & Data Types >Operators & Control Flow >Loops >Methods & Parameters >Classes & Objects >Inheritance & Polymorphism >Interfaces & Abstracts >Collections & LINQ >Exception Handling >Async / Await >Generics >Design Patterns

Start Stage 02 ->GitHub

SQL Server

Note: Design the database first. See data in SSMS before writing C# that touches it.

Build: 12-Table Schema - T-SQL, Stored Procs, Views, Indexes

>Database Design >CREATE TABLE, PK, FK >SELECT, INSERT, UPDATE, DELETE >JOINs - INNER, LEFT, RIGHT >Stored Procedures >Views >Indexes >RANK(), ROW_NUMBER()>SSMS - Query Tool

Start Stage 03 ->GitHub

Entity Framework Core

Note: Connect C# to SQL Server. This is when everything clicks - code reads and writes real data.

Build: ORM Layer - DbContext, All Relationships, Multi-tenant Filter, Audit Log

>DbContext & DbSet >Code First + Migrations >One-to-One Relationship >One-to-Many Relationship >Many-to-Many Relationship >Eager Loading - Include()>N+1 Problem & Fix >Global Query Filter (Tenant)>Dapper alongside EF Core

Start Stage 04 ->GitHub

ASP.NET Core MVC

Note: Build a real UI over the real database. Students, teachers, exams all visible in a browser.

Build: School Admin Portal - Razor UI with Full CRUD

>Middleware Pipeline >Dependency Injection >Controllers & Actions >Razor Views (.cshtml)>Model Binding & Validation >Cookie Authentication >Tag Helpers

Start Stage 05 ->GitHub

Web API + JWT Auth

Note: Expose the data as a secure REST API. Any frontend can consume it now.

Build: REST API - All CRUD + JWT + Swagger + Roles

>REST Principles >HTTP Verbs & Status Codes >DTOs & Guid (not int Id)>JWT Authentication >Role-Based Authorization >Swagger / OpenAPI >CORS & API Versioning

Start Stage 06 ->GitHub

Dapper

Note: Complex reports alongside EF Core. See when raw SQL wins over the ORM.

Build: Report Queries - Results, Fees, Attendance Summary

>Dapper vs EF Core >QueryAsync & ExecuteAsync >Multi-mapping JOIN results >Stored Proc via Dapper

Start Stage 07 ->GitHub

React Frontend

Note: First JavaScript frontend - calls the Stage 06 API. Same data, new interface.

Build: Student Portal UI - Login, Dashboard, Results, Fee Status

>React Components & JSX >useState & useEffect >Fetch API - GET/POST/PUT >JWT in localStorage >Protected Routes

Start Stage 08 ->GitHub

Angular (Bonus)

Note: Same API, different framework. One backend serves multiple frontends.

Build: Same Portal in Angular - HttpClient, Guards, Reactive Forms

>Angular Components & Modules >HttpClient & Services >AuthGuard & Routes >Reactive Forms

Start Stage 09 ->GitHub

Blazor (Bonus)

Note: Write frontend in C# - no JavaScript. Strong differentiator in interviews.

Build: Student Portal in Blazor - Pure C#, No JavaScript

>Blazor Server vs WebAssembly >Razor Components >Data Binding - @bind >Auth in Blazor

Start Stage 10 ->GitHub

Razor Pages (Bonus)

Note: Simpler than MVC for page-focused apps. Razor Pages vs MVC is a common interview question.

Build: Student Self-Service Portal - View Results, Fee Status

>Razor Pages vs MVC >PageModel - OnGet/OnPost >BindProperty >Routing - @page

Start Stage 11 ->GitHub

Full Stack + AzureJob Ready

Note: Deploy everything to Azure. Real URL, real DB, real app. Show it in your interview.

Build: Complete System - API + MVC + React + SQL Server - Live on Azure

>Azure App Service (API)>Azure SQL Database >Azure Static Web Apps >GitHub Actions CI/CD >Production Checklist
