Exploring TUnit, a modern take on .NET testing

Tue, 27 Jan 2026 00:00:00 +0000

The .NET testing ecosystem has been dominated for years by well‑established frameworks such as xUnit, NUnit, and MSTest. They are mature, stable, and battle‑tested. But as .NET itself evolves, becoming faster, more async‑friendly, and more careful about performance, new tools are emerging to better match these modern expectations.

One of the most interesting newcomers is TUnit .

In this article, we’ll try to explore what TUnit is, its core concepts and advantages, but also explore concrete examples of tests compared to xUnit.

Tue, 02 Dec 2025 00:00:00 +0000

Introduction

It’s been a recurrent meeting every 2 years, as this month Microsoft gave us the chance to try and adopt the new LTS version of our beloved framework, which is .NET 10 🔥
In this post, I’ll show you what are the big new improvements and features in this new LTS version, and also how to migrate your apps, which, you will see, has not changed a lot since the previous versions and this is a pretty good point.

Combining memory and distributed cache with HybridCache

Exploring the new HybridCache in .NET

New major dotnet releases always come with their bunch of new interesting features.
With the release of .NET 9, Microsoft introduced a powerful new caching mechanism called HybridCache. It’s designed to combine the benefits of both in-memory and distributed caching, providing better performance and scalability for modern applications. Let’s dive into it 😎

What is HybridCache?

HybridCache is a new caching abstraction that intelligently uses both:

Beware of Task.Run() !

Introduction

Hey all ! 🫡

A little post to share some thoughts about the Task.Run() method, and the problems you could encounter especially in a .NET API using a GlobalExceptionHandler. ❌

What actually happen when you need to start a Task as “fire and forget”, and you have an ExceptionHandler configured globally ?

This kind of case can happen frequently, for example if you need to await a particular business process, and start some tasks after that process that does not need to be awaited by the calling context.

How to migrate your application to .NET 8 ?

Wed, 14 Feb 2024 00:00:00 +0000

Introduction

Hey devs !

As you may all know, the new version of .NET, .NET 8, has been released on November 14 2023. A lot of you may have applications still in .NET 6 or earlier.
The end of support date for .NET 6 is November 12, 2024, so it’s good considering migrating your applications right now.
In this article, we’ll see what improvements brings .NET 8, and how to migrate your applications.
Microsoft has done a good job to make it easy for us to migrate from .NET 6 to .NET 8, or .NET 7 to .NET 8 (at least if you don’t rely on a Blazor app…), so we might as well make the most of it 😁
