.NET 6 latest features with coding example

Here are some of the latest features in .NET 6, along with examples of how to use them:

Minimal APIs: This is a new feature in .NET 6 that allows you to create lightweight HTTP endpoints with a minimal amount of code. Here's an example of how to create a minimal API that returns a simple string:

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

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

app.Run();

WebAssembly Blazor: This is a new way to create web applications in .NET 6 that allows you to run C# code directly in the browser using WebAssembly. Here's an example of how to create a simple WebAssembly Blazor application that displays a message:

html
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Blazor App</title>
    <base href="/" />
    <script src="_framework/blazor.webassembly.js"></script>
</head>
<body>
    <app>
        Loading...
    </app>
</body>
</html>

csharp
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("app");
await builder.Build().RunAsync();

Hot Reload: This is a new feature in .NET 6 that allows you to make changes to your code while your application is running, and see those changes reflected immediately without having to rebuild and redeploy your application. Here's an example of how to use hot reload in a Blazor application:

csharp
// Enable hot reload in development mode
builder.Services.AddBlazorHotReload();

var app = builder.Build();

// Run the application
await app.RunAsync();

Async streams: This is a new feature in .NET 6 that allows you to consume and produce data using asynchronous streams. Here's an example of how to use an asynchronous stream to generate a sequence of random numbers:

csharp
using System.Threading.Tasks;

public async IAsyncEnumerable<int> GenerateRandomNumbersAsync(int count)
{
    var random = new Random();
    for (int i = 0; i < count; i++)
    {
        await Task.Delay(1000); // simulate a delay
        yield return random.Next(1, 100);
    }
}

Performance improvements: .NET 6 includes a number of performance improvements, such as faster startup times, reduced memory usage, and improved throughput. These improvements can be especially beneficial for web applications that need to handle a large number of requests.
