C# 12: Default Parameters in Lambdas
There is still a long road ahead of us until the release of .NET 8, but the first new language constructs are getting public. The first one I want to present is: Default Parameters in Lambdas.
Hey, I'm Steven a .NET Developer in Switzerland. I am a Microsoft MVP. Also, this blog is open source on GitHub.

Many know that you can take ReadOnlySpan<char>
objects when dealing with string
s. They give you a direct way of operating on the underlying memory. Often times you can use them interchangeably, but there are scenarios where you really have to watch out what is going on.
This blog post will have a look at a major problem with ReadOnlySpan
when used like a "regular" string
.
Does your Dependency Injection container is one big pile of method calls one after the other?
Are there 50 lines of just AddScoped
, AddTransient
, and so on? Well, let's fix this.
We can utilize extension methods to make an order to that mess!
.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.
