Hey, I'm Steven a .NET Developer in Switzerland. I am a Microsoft MVP. Also, this blog is open source on GitHub.
In this short blog post, I want to showcase three nice tricks you can do with everybody's favorite data type: the dictionary.
It is a versatile data structure, and we can make it even more versatile!
On a recent LinkedIn Post from Saeed Esmaeelinejad, he asked what is the outcome of:
bool flag = SomeMethod();
M(flag ? 1 : 2);
void M(long number) => Console.WriteLine("long");
void M(short number) => Console.WriteLine("short");
What is the outcome?
In almost all of my projects, I only use xUnit, and here is a small love letter. Especially the one fact I do think makes it a good choice!
LINQ is a very powerful tool for querying data. As the majority of functions are built on top of IEnumerable<T> and it, in most cases returns IEnumerable<T> as well, it is very easy to chain multiple functions together. That leaves you with a question: which one should I use, Select.Where or Where.Select?
You may have heard that when you elide the await keyword in a method that returns a Task or Task<T>, you lose the stack trace. Buy why does that happen? Let's find out!
In this blog post, I'll show you the fundamentals of the Mediator pattern and how to implement it in your application from scratch. And yes, we basically implement the famous MediatR library.
A new feature is hitting C# 12 and it is called Collection literals. In this blog post, I will show you what it is and how it works.
A List is one of the most used data types in .NET. You can dynamically add elements without taking care of how that happens. But do you know what is going on under the hood?
There are many different memory types used in modern C# programs. The more common ones are Span<T> and Memory<T>. Occasionally there is also ReadOnlySequence<T>. What do these types do?
With the upcoming release of .NET, the team introduced an abstraction of time itself. That can bring you major benefits especially if you have to test scenarios where time is a crucial part! Until now, you had to create your own wrapper. This, of course, makes integration with 3rd party libraries tricky.
