A popular unit test - and also a necessary test - is the correct registration of interfaces and their implementation with dependency injection. And a common mistake is that the associated IServiceCollection interface is used for mocks that lead to faulty tests.
Read Blog PostWhen working with ZIP files in .NET, there may be cases where the file is not stored on disk but comes directly as a Stream. This could happen if you’re downloading the ZIP file from a network, receiving it via an API or working with in-memory file data. In this blog post, I’ll show you a simple example of handling ZIP files using streams in .NET and how to process their content without saving the ZIP to disk.
Read Blog PostWorking with compressed files is common in many applications, whether you’re extracting data from an archive, installing software packages or retrieving bundled files. Thankfully, .NET finally provides an efficient, straightforward way to decompress ZIP files using the System.IO.Compression namespace. In this post, I’ll walk through a simple code snippet that you can use to decompress ZIP files in your .NET apps.
Read Blog PostWhen working with .NET apps you may sometimes need to bundle multiple files into a single compressed archive for easier storage, transfer or processing. In this post, I’ll show you a simple and effective way to compress a folder into a .zip file using just a few lines of code with the built-in .NET namespace System.IO.Compression .
Read Blog PostIn C# (.NET 6 and above), there is now a very simple way to read out the CPU load with minimal overhead - i.e. without threads. The PerformanceCounter from the System.Diagnostics namespace helps us with this.
Dealing with empty lists is an everyday situation in .NET. An empty list is often preferred to a null in order to control the logic. But how expensive is it to return an empty list?
We are currently in the preview phase of .NET 9 , which releases in Nov 2024 - and if you want to test it extensively like I do, store the preview version in the global configuration global.json . But how do you have to define the version here for it to work?

Strings are one of the most commonly used types in .NET applications - and very often the source of inefficient code. For example, cleaning up a string - such as removing invalid or non-visible characters - is one of the most common use cases for user input. Unfortunately, the most convenient, but not the most efficient, implementation imaginable is used in this case: Linq.
Read Blog PostRefit is an open-source library for .NET developers that simplifies the process of making HTTP API calls. It allows developers to define a set of interfaces that describe the API endpoints they want to interact with and then Refit automatically generates the necessary code to make the HTTP requests. This can significantly reduce boilerplate code and make the interaction with web APIs more type-safe and maintainable.
Read Blog PostStrong Name Signing is a mechanism in .NET development that ensures the integrity and authenticity of assemblies. It is based on a public-private key procedure.
Contrary to what many assume, this is not a security mechanism, but a mechanism to ensure the uniqueness of the identity. It is therefore also recommended to store both private and public keys directly in the repository - and not to hide them; especially not in open source projects.
