🔍 ASP.NET – What It Is
ASP.NET is a web framework for building modern web apps on the .NET platform.
✅ Supports:
- Web Forms (older)
- MVC (Model-View-Controller)
- Razor Pages
- ASP.NET Core (cross-platform)
- Blazor (WebAssembly)
⚙️ ASP.NET – Environment Setup
🛠 Requirements:
- .NET SDK (Latest LTS version)
- Visual Studio / VS Code with ASP.NET support
- Browser (Edge, Chrome, etc.)
🔹 Install Steps:
# Install .NET SDK
https://dotnet.microsoft.com/en-us/download
# Create ASP.NET project (CLI)
dotnet new webapp -o MyWebApp
cd MyWebApp
dotnet run
✅ Visit http://localhost:5000 to view your app.
🧪 ASP.NET – First Example
Create a new ASP.NET Core Razor app:
dotnet new razor -o HelloWorldApp
cd HelloWorldApp
dotnet run
Then navigate to Pages/Index.cshtml:
<h2>Hello from ASP.NET</h2>
<p>This is your first web page!</p>
🧠 Razor Pages use .cshtml (C# + HTML) and make dynamic rendering easy.
🔁 ASP.NET – Life Cycle Overview
💡 Stages of ASP.NET Request:
- Page Request – Client requests a page (e.g.,
.aspx,.cshtml) - Start & Initialization – Server prepares the environment
- Load – ViewState, controls, and data loaded
- Postback Handling – Events like button click executed
- Render – HTML is generated and sent to client
- Unload – Cleanup code executes (e.g., closing DB)
✅ Each step allows hooks like Page_Load, OnInit, etc.
📑 ASP.NET – Quick Reference Guide
| ⚙️ Component | 💡 Description |
|---|---|
Page_Load() | Executed on every request |
.cshtml | Razor syntax combining C# with HTML |
dotnet run | Command to run ASP.NET Core apps |
Startup.cs | Configures middleware, routes, and services |
Program.cs | Entry point to the ASP.NET app |
