.NET 10 is de huidige Long-Term Support (LTS) release en brengt native validatie voor Minimal APIs, standaard OpenAPI 3.1-ondersteuning en aanzienlijke performance-verbeteringen. ASP.NET Core combineert C# met een modulaire architectuur die geschikt is voor enterprise-applicaties. Deze gids behandelt het bouwen van een productie-klare REST API, van de initiele setup tot deployment.

.NET 10 LTS

.NET 10 wordt ondersteund tot eind 2028. Ingebouwde validatie voor Minimal APIs, OpenAPI 3.1-ondersteuning en Native AOT-verbeteringen maken het de optimale keuze voor nieuwe API-projecten.

Projectconfiguratie met .NET 10 CLI

Het aanmaken van een ASP.NET Core API-project gebeurt via de .NET CLI, die een geoptimaliseerde projectstructuur genereert. De configuratie van essentiele NuGet-pakketten legt de basis voor de ontwikkeling.

bash

# terminal
# Check installed .NET version
dotnet --version
# Expected: 10.0.x

# Create the API project
dotnet new webapi -n ProductApi -o ProductApi
cd ProductApi

# Add essential packages
dotnet add package Microsoft.EntityFrameworkCore.SqlServer
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet add package Swashbuckle.AspNetCore

Deze commando's maken een API-project aan met afhankelijkheden voor Entity Framework Core en Swagger-documentatie. FluentValidation is niet langer nodig voor basisvalidatie in .NET 10.

Program.cscsharp

using Microsoft.EntityFrameworkCore;
using ProductApi.Data;
using ProductApi.Services;

var builder = WebApplication.CreateBuilder(args);

// Configure Entity Framework Core with SQL Server
builder.Services.AddDbContext<AppDbContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));

// Register business services
builder.Services.AddScoped<IProductService, ProductService>();
builder.Services.AddScoped<ICategoryService, CategoryService>();

// Configure controllers with built-in validation (.NET 10)
builder.Services.AddControllers();
builder.Services.AddValidation();

// Configure OpenAPI 3.1 (default in .NET 10)
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new() { Title = "Product API", Version = "v1" });
});

var app = builder.Build();

// Middleware pipeline
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();

app.Run();

De AddValidation()-methode activeert de ingebouwde validatie die is geintroduceerd in ASP.NET Core 10, waardoor third-party bibliotheken zoals FluentValidation voor veelvoorkomende scenario's overbodig worden.

Datamodellen en Entity Framework Core 10

Modellen vertegenwoordigen de business-entiteiten van de applicatie. Entity Framework Core verzorgt de object-relationele mapping met fluent configuratie en slimme conventies.

Models/Product.cscsharp

namespace ProductApi.Models;

public class Product
{
    // Primary key with auto-increment
    public int Id { get; set; }

    // Required properties (non-nullable in C# 14)
    public required string Name { get; set; }
    public required string Description { get; set; }

    // Price with decimal precision
    public decimal Price { get; set; }

    // Stock with default value
    public int StockQuantity { get; set; } = 0;

    // Product status
    public bool IsActive { get; set; } = true;

    // Relationship with Category (foreign key)
    public int CategoryId { get; set; }
    public Category? Category { get; set; }

    // Automatic tracking dates
    public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
    public DateTime? UpdatedAt { get; set; }
}

Het required keyword zorgt ervoor dat essentiele properties altijd geinitialiseerd worden bij het aanmaken.

Models/Category.cscsharp

namespace ProductApi.Models;

public class Category
{
    public int Id { get; set; }

    public required string Name { get; set; }

    // Slug for friendly URLs
    public required string Slug { get; set; }

    public string? Description { get; set; }

    // Inverse navigation: list of products in this category
    public ICollection<Product> Products { get; set; } = new List<Product>();

    public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
}

Data/AppDbContext.cscsharp

using Microsoft.EntityFrameworkCore;
using ProductApi.Models;

namespace ProductApi.Data;

public class AppDbContext : DbContext
{
    public AppDbContext(DbContextOptions<AppDbContext> options) : base(options)
    {
    }

    // DbSets for each entity
    public DbSet<Product> Products => Set<Product>();
    public DbSet<Category> Categories => Set<Category>();

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Product entity configuration
        modelBuilder.Entity<Product>(entity =>
        {
            // Index on name for fast search
            entity.HasIndex(p => p.Name);

            // Price precision: 18 digits, 2 decimals
            entity.Property(p => p.Price)
                .HasPrecision(18, 2);

            // Relationship with Category
            entity.HasOne(p => p.Category)
                .WithMany(c => c.Products)
                .HasForeignKey(p => p.CategoryId)
                .OnDelete(DeleteBehavior.Restrict);
        });

        // Category entity configuration
        modelBuilder.Entity<Category>(entity =>
        {
            // Unique slug
            entity.HasIndex(c => c.Slug).IsUnique();

            // Maximum name length
            entity.Property(c => c.Name).HasMaxLength(100);
        });
    }
}

De Fluent API-configuratie biedt nauwkeurige controle over het databaseschema dat door EF Core-migraties wordt gegenereerd.

Entity Framework Core Migrations

Migraties versioneren het databaseschema. Voer dotnet ef migrations add InitialCreate uit, gevolgd door dotnet ef database update om de wijzigingen toe te passen.

DTO's en Ingebouwde Validatie in ASP.NET Core 10

DTO's (Data Transfer Objects) scheiden domeinmodellen van de data die via de API wordt blootgesteld. ASP.NET Core 10 introduceert ingebouwde validatie met DataAnnotations, waardoor third-party bibliotheken in de meeste gevallen overbodig worden.

DTOs/ProductDtos.cscsharp

using System.ComponentModel.DataAnnotations;

namespace ProductApi.DTOs;

// DTO for product creation with DataAnnotations
public record CreateProductDto(
    [Required(ErrorMessage = "Product name is required.")]
    [MaxLength(200, ErrorMessage = "Name cannot exceed 200 characters.")]
    string Name,

    [Required(ErrorMessage = "Description is required.")]
    [MinLength(10, ErrorMessage = "Description must contain at least 10 characters.")]
    string Description,

    [Range(0.01, 999999.99, ErrorMessage = "Price must be between 0.01 and 999,999.99.")]
    decimal Price,

    [Range(0, int.MaxValue, ErrorMessage = "Stock cannot be negative.")]
    int StockQuantity,

    [Required(ErrorMessage = "A valid category is required.")]
    int CategoryId
);

// DTO for product update
public record UpdateProductDto(
    [MaxLength(200)]
    string? Name,
    string? Description,
    [Range(0.01, 999999.99)]
    decimal? Price,
    [Range(0, int.MaxValue)]
    int? StockQuantity,
    bool? IsActive
);

// DTO for response (read)
public record ProductDto(
    int Id,
    string Name,
    string Description,
    decimal Price,
    int StockQuantity,
    bool IsActive,
    string CategoryName,
    DateTime CreatedAt
);

// DTO for list with pagination
public record ProductListDto(
    int Id,
    string Name,
    decimal Price,
    int StockQuantity,
    bool IsActive,
    string CategoryName
);

Het gebruik van C# records maakt DTO's onveranderlijk en beknopt, met automatische waardegelijkheid. De ingebouwde validatie retourneert automatisch gestructureerde 400-fouten wanneer validatie faalt. Voor sollicitatievoorbereiding over ASP.NET Core-patterns, zie de gids ASP.NET Core interviewvragen.

Het gebruik van ExecuteDeleteAsync verbetert de performance doordat het laden van de entiteit voor verwijdering wordt overgeslagen. Voor geavanceerde patterns, zie de gids Clean Architecture met .NET.

API Controllers en REST Endpoints

Controllers stellen REST-endpoints beschikbaar en orchestreren aanroepen naar business services met passende HTTP-statuscode-afhandeling.

De ProducesResponseType-attributen documenteren mogelijke responscodes voor automatische Swagger-documentatiegeneratie.

DTOs/PaginatedResponse.cscsharp

namespace ProductApi.DTOs;

public class PaginatedResponse<T>
{
    public IEnumerable<T> Items { get; set; } = Enumerable.Empty<T>();

    public int TotalPages { get; set; }
    public bool HasPreviousPage => Page > 1;
    public bool HasNextPage => Page < TotalPages;
}

Route Constraints

Het gebruik van constraints zoals {id:int} voorkomt routing-conflicten en retourneert automatisch een 404 als het formaat niet klopt.

Globale Foutafhandelingsmiddleware

Een foutafhandelingsmiddleware centraliseert de verwerking van uitzonderingen voor consistente en veilige responses.

    }
}

Program.cs (adding middleware)csharp

Configuratie en Omgevingsvariabelen

Geexternaliseerde configuratie maakt het mogelijk de applicatie aan te passen aan verschillende omgevingen zonder codewijzigingen.

Checklist voor Productie .NET API's

.NET 10 met ASP.NET Core biedt een compleet en performant ecosysteem voor het bouwen van professionele REST API's. De combinatie van ingebouwde validatie, Entity Framework Core voor datatoegang en native dependency injection maakt het mogelijk onderhoudbare en testbare applicaties te bouwen.

DTO's scheiden van domeinmodellen
Servicelaag voor bedrijfslogica implementeren
Ingebouwde validatie met DataAnnotations gebruiken (.NET 10+)
Globale foutafhandelingsmiddleware configureren
Configuratie externaliseren met IOptions
Unit tests voor services schrijven
API documenteren met OpenAPI 3.1

Begin met oefenen!
