.NET

"A Visual Studio extension that checks and notifies about available updates for the installed NuGet packages for the open solution."

This time no fancy new features, but a complete refactor of the project structure which will keep the extension easy to maintain.

Thanks goes to @tomenglert

While implementing AutoMapper in some existing code, I came across the need to map to a nullable property. Other business logic relied on this particular long being null instead of 0. The DTO has a property that contains a (long)Id, but the Entity contains the virtual property as well as a nullable long? of the Id. Anyway after fumbling through a few tries, I finally came upon the solution and wanted to share it here.

In the MapperProfile for the direction of DTO to Entity you have to do a null check, but the trick for me was having to explicitly cast to (long?)null.

CreateMap<ExampleDto, ExampleEntity>().ForMember(ee => ee.ExampleId, options => options.MapFrom(ed => ed.ExampleProperty != null ? ed.ExampleProperty.ExampleId : (long?)null)).NoVirtualMap();

Hope someone else finds this helpful, and finds it here.

We’re delighted to let you know about the latest features and improvements coming with .NET 8 Preview 6! This release is a continuation of the Preview 5 release, and we’re committed to bringing you more enhancements with each monthly release.

Today we have an exciting release incorporated with plenty of library updates, a new WASM mode, more source generators, constant performance improvements, and NativeAOT support on iOS. We hope you enjoy these new features and improvements. Stay tuned for more updates as we continue our journey of making .NET better, together!

I just personally love them and I am looking to get a deeper understanding of them and how to implement them.

Do you chaps have any good resources? (Articles, nuget packages, etc.)

Today, we’re excited to announce that Microsoft Dev Box is now generally available. Below we’ll highlight a few significant features of Dev Box for Visual Studio users. Read the announcement blog to learn more about our journey to Microsoft Dev Box and what the service means for Visual Studio subscribers.

Today, we’re releasing an update to the System.Web Adapters that simplify upgrading from ASP.NET to ASP.NET Core. This release brings a number of fixes as well as new scenarios that we’ll explore in this post.

The documentation uses is in the example for "declaration patterns" but the book I am reading uses a switch statement. But when I try to run the code I run into errors.

using System;

public class Program
{
  public static void Main()
  {
    var o = 42;

    switch (o) {
      case string s:
        Console.WriteLine($"A piece of string is {s.Length} long");
        break;

      case int i:
        Console.WriteLine($"That's numberwang! {i}");
        break;
    }
  }
}

Error:

Compilation error (line 7, col 6): An expression of type 'int' cannot be handled by a pattern of type 'string'.

EDIT

Changing from

var o = 42;

to

object o = 42;

worked.

What does "control falls through a switch statement" mean in this context? Control just moves on to the next statement?

I thought if there is no match and a default case doesn't exist it will raise an exception. Is it not true?

Many of us consider instrumentation as boring infrastructure. But, with the popularity of microservices architecture, its importance have significantly increased. Alex Thissen explains logging, metrics and tracing from .NET (and Azure) point of view. I think we should focus more on OpenTelemetry, but this is a good start.
