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 [ Article ] : https://devblogs.microsoft.com/dotnet/check-out-csharp-12-preview 〰️〰️〰️〰️〰️〰️ #CSharp #DotNet @ProgrammingTip

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
}
