Programming & AI Tips 💡

Check out new C# 12 preview features! ⚡️

Three new features for C# 12 😮 :

1️⃣- Primary constructors for non-record classes and structs :

public class Student(int id, string name, IEnumerable<decimal> grades)
{
    public Student(int id, string name) : this(id, name, Enumerable.Empty<decimal>()) { }
    public int Id => id;
    public string Name { get; set; } = name.Trim();
    public decimal GPA => grades.Any() ? grades.Average() : 4.0m;
}

2️⃣- Using aliases for any type:

using Measurement = (string, int);

public void F(Measurement x)
{ }

3️⃣- Default values for lambda expression parameters:
var addWithDefault = (int addTo = 2) => addTo + 1;
addWithDefault(); // 3
addWithDefault(5); // 6

WireMock.NET 😮

WireMock.NET is a .NET library for stubbing and mocking HTTP services. With WireMock.NET, you can define the expected responses for particular requests, and the library will intercept and manage those requests for you. ✔️

This allows for easy testing of the code that makes HTTP requests, without having to rely on the actual external service being available and without hacking HttpClient. 🆒

Sample code snippet:

[Test]
public async Task sample_WireMock_usage()
{
  // Setup WireMock.Net server
  using var wireMock = WireMockServer.StartWithAdminInterface(port: 1080, ssl: false);
  
  // Setup WebApplicationFactory
  await using var appFactory = new WebApplicationFactory<Program>().WithWebHostBuilder(builder =>
  {
    builder.ConfigureAppConfiguration(configurationBuilder =>
    {
      // Override downstream service addresses pointing to WireMock address
      configurationBuilder.AddInMemoryCollection(new Dictionary<string, string>
      {
        ["ExternalServices:WeatherService"] = "http://localhost:1080"
      });
    });
  });

  // Prepare stub for outgoing request
  wireMock
    .Given(
        Request.Create()
            .WithPath("/api/v1.0/weather")
            .WithParam("lat", "10.99")
            .WithParam("lon", "44.34")
            .UsingGet()
    )
    .RespondWith(
        Response.Create()
            .WithStatusCode(200)
            .WithHeader("Content-Type", "application/json; charset=utf-8")
            .WithBodyAsJson(new
            {
                temp = 298.48,
                feels_like = 298.74,
                temp_min = 297.56,
                temp_max = 300.05,
                pressure = 1015,
                humidity = 64
            })
    );

    // Automate tested app
}

Source Link 🐞

Source Link is a language- and source-control agnostic system for providing first-class source debugging experiences for binaries.

The goal of the project is to enable anyone building NuGet libraries to provide source debugging for their users with almost no effort.

Microsoft libraries, such as .NET Core and Roslyn have enabled Source Link.

Source Link is supported by Microsoft. ✅

Nuke Build 🗂

As C# developers, we are spoiled with a great language and awesome IDEs.

Why do most automation systems never really match the level of convenience and integration that we're used to?

NUKE is different. 💎

It is fully based on C# console applications and uses the type system to its full extent.

You want your auto-completion, package management, debugging, refactorings, formatting, and navigation back? It’s available right there❗️

Functional architecture - The pits of success ✅

Object-oriented architects and developers have, over the years, learned many hard lessons about successfully designing systems with object-oriented programming. This has led to a plethora of ‘best practices’ that are painfully passed on from older to younger generations via books, lectures, consulting, blog posts, etc.

Many of these ‘best practices’ must be explicitly taught, because they don’t evolve naturally from object-oriented programming. Surprisingly, many of these hard-won ‘best practices’ fall naturally into place when applying functional programming.

Instead of deliberate design, functional programming forms pits of success where you naturally fall into the same ‘best practices’ that you have to deliberately work for in object-oriented programming.

In this session, you’ll learn about a handful of such ‘best practices’, and how functional programming automatically leads you there, without your explicit effort.

Looking inside ConfigurationManager in .NET 6 ✅

ConfigurationManager was added to support ASP.NET Core's new WebApplication model, used for simplifying the ASP.NET Core startup code. 🧹

However ConfigurationManager is very much an implementation detail. It was introduced to optimise a specific scenario (which I'll describe shortly), but for the most part, you don't need to (and won't) know you're using it.

In this post, We take a look at the ConfigurationManager class, why it was added, and some of the code used to implement it.

Lowering in C#: What's really going on in your code? 👾

If you're attending NDC you probably think you know what a foreach loop does - it iterates over a collection, right? ✅

BUT do you know how? Do you know what the C# compiler does when you write a foreach loop? What about a lambda expression? Or the re-entrant magic that is a yield return statement❓

In this session we'll dive into Roslyn, the C# compiler, and learn about lowering and how it helps the compiler do its job, and what it does to your code. In the process you'll gain the skills to identify some of the common performance pitfalls of .NET, as well as just get a deeper understanding of what the code you write really does. 💎

The Soul of Erlang and Elixir • Saša Jurić • GOTO 2019 ✨

Whether you're developing a small web site or a large-scale distributed system, Erlang and Elixir are great tools for building server-side systems. Both languages can help you start quickly and deal with highly complex problems at a large scale. 💨

This talk aims to explain what makes Erlang and Elixir suitable for such tasks. We'll look past the syntax and the ecosystem, focusing instead on the concurrency model of these languages.

Combining a bit of high-level theory and a couple of demos, we'll examine some important properties of Erlang/Elixir concurrency, with a special emphasis on why these properties are very relevant when building highly available systems.

The talk targets experienced backend developers, but no knowledge of Erlang or Elixir is required. ✅

DDD, Hexagonal, Onion, Clean, CQRS, … How I Put It All Together 🚀

I start by recalling EBI and Ports & Adapters architectures. Both of them make an explicit separation of what code is internal to the application, what is external, and what is used for connecting internal and external code.

Furthermore, Ports & Adapters architecture explicitly identifies three fundamental blocks of code in a system:

What makes it possible to run a user interface, whatever type of user interface it might be.

- The system business logic, or application core, which is used by the user interface to actually make things happen.

- Infrastructure code, that connects our application core to tools like a database, a search engine or 3rd party APIs.
