.NET 8 přináší performance improvements, native AOT compilation a nové C# 12 features.
C# 12 features¶
// Primary constructors public class User(string name, string email) { public string Name => name; public string Email => email; public string Display() => $”{Name} <{Email}>”; } // Collection expressions int[] numbers = [1, 2, 3, 4, 5]; List names = [“Jan”, “Eva”, “Tom”]; // Default lambda parameters var greet = (string name = “World”) => $”Hello {name}!”;
Minimal API¶
var builder = WebApplication.CreateBuilder(args); var app = builder.Build(); app.MapGet(“/api/users”, async (AppDbContext db) => await db.Users.ToListAsync()); app.MapPost(“/api/users”, async (User user, AppDbContext db) => { db.Users.Add(user); await db.SaveChangesAsync(); return Results.Created($”/api/users/{user.Id}”, user); }); app.Run();
Klíčový takeaway¶
Primary constructors, collection expressions, minimal API. .NET 8 = LTS, native AOT pro microservices.
