.NET 8 - Keyed service dependency injection container support 🔝
Keyed services are useful when you have an interface/service with multiple implementations that you want to use in your app. What's more, you need to use each of those implementations in different places in your app. ☄️
Sample:var builder = WebApplication.CreateBuilder(args);[ Article ] : https://andrewlock.net/exploring-the-dotnet-8-preview-keyed-services-dependency-injection-support
builder.Services.AddKeyedSingleton<INotificationService, SmsNotificationService>("sms");

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.

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. 💎

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][ Blog ] : https://cezarypiatek.github.io/post/mocking-outgoing-http-requests-p1
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

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.

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. ✅
