Comparison with Previous Versions

.NET 7 vs. .NET 8

- Performance: .NET 8 brings further performance enhancements over .NET 7.

- Platform Unity: Continued progress towards a unified platform in .NET 8.

- Tooling: Enhanced developer tools and productivity features in .NET 8.

Code Examples

Example 1: Minimal API Improvements

var builder = WebApplication.CreateBuilder(args);

var app = builder.Build();

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

app.Run();        

.NET 8 makes it even easier to create minimal APIs with improved syntax and performance.

Example 2: Enhanced Authentication

builder.Services.AddAuthentication(options =>

{

    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;

    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;

})

.AddJwtBearer(options =>

{

    options.Authority = "https://your-auth-provider.com";

    options.Audience = "your-api";

});

app.UseAuthentication();

app.UseAuthorization();        

.NET 8 includes better support for authentication mechanisms, making it easier to secure your APIs.

Daily Life Example: E-Commerce Application

Imagine you’re developing an e-commerce application. With .NET 8, you can:

- Optimize Performance: Ensure your application can handle high traffic during sales events.

- Unify Development: Use the same platform to build both the web front-end and mobile app.

- Enhance Security: Protect customer data with improved security features.

- Leverage Cloud: Seamlessly integrate with cloud services to manage inventory and process payments.
