# ASP.NET Core

Cross-platform, high-performance framework for building modern web apps.

## When to Use

- High-performance APIs (one of the fastest benchmarks)
- Enterprise applications
- Microservices
- Real-time apps (SignalR)

## Quick Start

```csharp
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/", () => "Hello World!");

app.Run();
```

## Core Concepts

### Middleware Pipeline

Request processing pipeline composed of delegates.

### Dependency Injection

Built-in DI container, a core citizen of the framework.

### Kestrel

Cross-platform web server for ASP.NET Core.

## Best Practices

**Do**:

- Use the built-in DI
- Use asynchronous controllers (`async Task<IActionResult>`)
- Use Environment Variables for config settings

**Don't**:

- Block asynchronous code (`.Result` or `.Wait()`)
- Store large objects in Session state
