Hey, I'm Steven a .NET Developer in Switzerland. I am a Microsoft MVP. Also, this blog is open source on GitHub.
.NET knows a big list of collection-like types like: IEnumerable, IQueryable, IList, ICollection, Array, ISet, ImmutableArray, ReadOnlyCollection, ReadOnlyList, and many more.
This blog post will give you an exhaustive list of types in .NET and when to use what.
This blog post will show you a very simple Dependency Injection container.
This will give a better understanding of what Dependency Injection is and how it is done. And sure we will see how this is related to IoC - Inversion of Control.
Sometimes you have an Id of an object and want to delete the underlying thing from the database. But it doesn't make sense to load the whole object from the database to memory first. So how can we achieve this quickly?
ChatGPT is going viral right now. Besides funny conversations, you can use that tool to generate also code for you. But does it really hold up to its reputation and it is a serious pairing partner? Let's see.
In the past, it was tricky to get if the current process runs under elevated rights. In the sense of it is run under the sudo group in *nix (Unix, Linux, macOS, you name it) or administrative rights in Windows.
But that changes with .NET 8 as we now have a unified API for that.
Abstraction and Encapsulation are two fundamental concepts in object-oriented programming. So let us have a small look what the difference is between those two.
Did you ever wonder how we can iterate through a StringBuilder? I mean, of course, we can just call ToString and use the returned string, but that means we materialize the whole thing without good reason.
We can also use a normal for-loop. But we can also find a completely different and probably dumber way! And if you wonder: No, this is not something you do in your daily life, but by doing so, I can show some cool stuff C# and .NET offer.
Do you remember how .NET 6 introduced the ArgumentNullException.ThrowIfNull guard? And afterward, with .NET 7 we've got this excellent bit: ArgumentException.ThrowIfNullOrEmpty? Guess what, there might come some new handy additions for the upcoming .NET 8 iteration.
So let's see what are those new changes and how they make the code simpler.
Analyzers did become an integral part of the .NET ecosystem. Their main responsibility is to find potential code issues and warn you. Often times this comes even with potential fixes you can directly apply.
And Microsoft will continue this journey with the upcoming .NET 8 release. This blog post will show you potential candidates, which will make the cut.
.NET 7 was freshly released but Microsoft does not sleep. .NET 8 is already in the making and I want to showcase to you one new area where the dotnet team is working on Frozen collections.
So let's have a look at what frozen collections are and how they are working.
