Create your own Mediator (like Mediatr)
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.
Hey, I'm Steven a .NET Developer and Freelancer in Zurich, Switzerland. I am a Microsoft MVP. Also, this blog is open source on GitHub.
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.
With preview 4 of .NET 8, a new terminal logger was introduced. It basically removes a lot of the noise that the default logger produces. It also adds some nice colors to the output. Let's see how to use it!
The nameof
operator is a great way to get the name of a variable, type, or member. With C# 12 it's getting even better. Let's see how.
TryGetNonEnumeratedCount
attempts to determine the number of elements in a sequence without forcing an enumeration. It returns true
if it could and false
if it couldn't. The API was added with .NET 6 - let's have a look at how that thing works.
I did already write about some useful extension methods for Task
and ValueTask
. Today I want to show you some useful extension methods for IEnumerable
.
In this blog post, we will explore some cool things you can do with ValueTuple
. Also, a short explanation of what ValueTuple
is and how it works.
