The key role of tests is to ensure that the software under test behaves correctly. But there's also value in test code being easy to read and understand. When a test breaks you want to quickly see wha...

Last year a wrote a blog post about restricting a REST API endpoint total response time but potentially continuing the processing in the background. I implemented it fully by hand without any external...

A while back I wrote a blog post about deserializing a JSON with a field of a variable type in .NET. At that time I used a custom serializer to achieve that. This scenario seems like a good fit for un...

Since a new version of .NET is being released every autumn, C# has also adopted the same cadence. So, this November C# 15 is going to be released alongside with .NET 11. In this talk, we will take a l...

Goto statements have been a part of C# since the very first version, but at least I haven't seen them being used very often. In C# 15, labels can also be used in combination with continue and break st...

Last year, extension members were the biggest new feature of C# 14. I wrote about them in detail in multiple blogposts. This year, extension indexers are being added to C# 15 which didn't make it into...

Collection expressions were introduced in C# 12. I wrote a blog post about them at that time. In C# 15, the syntax is being extended with the ability to provide additional arguments to the underlying ...

In the previous blog post I explored what union types bring to C#. But what does the compiler do under the hood? And do I need to know about that to fully take advantage of union types?

Continuing with the topic of switch expression exhaustiveness in C# 15, I chose union types as the next new language feature to explore.

The release of C# 15 is getting closer and its new features started to show up in the .NET 11 previews. That's a good time for me to take a closer look at what to expect. I'm starting with closed clas...

For over a year, I've been using restic to back up my home lab server to a repository on a Synology NAS mounted locally using NFS. All this time, it worked for me without any issues whatsoever. Only w...

I'm in the process of switching from Windows 11 to CachyOS on my home machine. Of course, my setup also includes .NET development tooling. And with the upcoming .NET 11 release, I want to have access ...

As a part of migrating my blog to Azure Static Web Apps, I also had to modify my GitHub Actions deployment workflow. Usually, I only want the deployment to get triggered from the main branch but durin...

After reimplementing redirects in Azure Static Web App using managed Azure Functions, there was one last redirect I couldn't implement in this way and had to find another solution for: redirecting all...

As I was implementing redirects in Azure Functions for my blog, I wanted to be able to test them as efficiently as possible. Although you can run and test an Azure function locally, and I did, I also ...

The biggest challenge of moving my blog to Azure Static Web Apps were the redirects. I still support permalinks from my previous blog engine and I previously used back-references in IIS rewrite module...

In the process of moving my blog to Azure Static Web Apps I had to troubleshoot a strange issue: according to logs the managed API Azure Functions have been successfully deployed, but according to Azu...

When you want to embed some static data in your TypeScript application, it's very convenient to store it as a JSON file and import it directly in a source code file. The compiler even implies static t...

There's an open source application plugin written in .NET I occasionally contribute to. As a regular part of my workflow, I sometimes have to attach the debugger to the application with the plugin loa...

Inspired by a great post in Bitwarden Community Forums and the author's bash script I decided to create my own PowerShell script for backing up the contents of my Bitwarden vault to my existing restic...

My restic backup script on Windows relied on having the restic password stored in an environment variable, making it and the restic command accessible to any process running with my credentials. Befor...

In the company I work for, we're not using Teams internally and our users don't have a license for it. But some of our customers do use Teams and pay for it. They also add users from our Entra ID whic...

I needed a simple way to disable all endpoints in a Quarkus application based on a configuration property. A request filter was the right tool for the job, but some care had to be taken to not also di...

IntelliJ IDEA does a great at managing multiple different JDK versions and using the right one for each project. However, a different solution is needed for the command line. I tried vfox, but I could...

I recently played around with having some version-controlled files on a remote Linux server with SSH access. I still wanted to edit them locally in Visual Studio Code, so the Remote - SSH extension se...

My work consists of writing code for multiple clients and for some of them I need to use a different email in my git commits. I recently learned that there is a better approach for handling this than ...

As I'm adding more services to my home lab server, I reached a point at which I want to expose some of them to the internet but keep others available only in the internal network. To securely do so fr...

I often have several tabs open in my Windows Terminal. And I like how I can easily identify the right one by its title if it's a tab for WSL or an SSH connection. Fortunately, PowerShell can also auto...

With Windows 10 support officially ending, I decided to install Linux Mint on one of my older machines which isn't supported by Windows 11. The transition was really smooth for the most part with the ...

When the support for trusted publishing on NuGet was announced, I decided to try switching to it for my side project as soon as possible. The process ended up being very smooth.

I mostly work remotely and to gain access to many work resources, I need a VPN connection to my office. When you connect, all of your network traffic is routed through the VPN connection by default. T...

Since a new version of .NET is being released every autumn, C# has also adopted the same cadence. So, this November C# 14 is going to be released alongside with .NET 10. In this talk, we will take a l...

Operator overloading has been a part of C# since its very first version. The functionality has remained the same until the introduction of generic math in C# 11 when some changes were made to shift op...

In my previous two blog posts, I wrote about extension members in general and generic extension members. But there's one more topic related to extension members I'd like to cover: how ambiguous extens...

I already wrote about extension members in C# 14 in my previous blog post, but I only covered the non-generic members. Since generics were fully supported in extension methods, they are of course also...

Extension members are the largest new feature of C# 14. We have been hearing about it for quite a while, also under the name of extension everything and extension types. It was expected to be released...

After getting a bug report that an ASP.NET Core Web API endpoint is returning 204 (No content) instead of 201 (Created), it turned out that the bug wasn't in the application code but in .NET.

The next C# 14 feature I took a closer look at was the field keyword. Similarly to the null-conditional assignment, it can reduce some of the boilerplate code you need to write. But it's not just synt...

As the release of C# 14 is coming closer and most of the features are already available in preview, I decided to try them out myself. I started with null-conditional assignment, a syntactic sugar feat...

When JetBrains announced the availability of an OpenTelemetry plugin for Rider, I decided to give it a try. I've examined the options for OpenTelemetry collection during development in the past and wa...

When an ASP.NET Core Web API REST service endpoint makes further calls to upstream REST services or interacts with other potentially slow resources, its response time strongly depends on the response ...

After I successfully configured restic backup for my Linux home lab server, I wanted to do the same for my Windows workstation.

Since I bought an ASUS NUC some months ago to act as my home lab server, I started to rely on a couple of applications running on it. That meant it was time to set up a proper backup as a safeguard in...

As I'm slowly replacing cloud services with self-hosted ones, I'm relying on my Synology NAS more and more. This encouraged me to rethink its backup strategy. I configured two separate backups: one to...

Nowadays, it's common to send logs to your logging platform of choice either via a dedicated logger for that platform or via an OpenTelemetry exporter. But what if the logs have to be read from a file...

After my latest (not so) regular update of installed PowerShell modules, I was surprised by a breaking change in the Oh My Posh module. Fortunately, a link to an online migration guide was displayed d...

While learning about Fast Node Manager, I noticed completions for PowerShell being mentioned in the documentation. I wasn't aware of completions beyond filenames and cmdlets were even supported in Pow...

When I visited the official Node.js download page after a long time, I noticed fnm (Fast Node Manager) listed as the default download option. I've been successfully using NVM for Windows as the versio...

As I was troubleshooting my issues with Elastic logger configuration, I couldn't get the debugging in Visual Studio 2022 to work for the Elastic.Extensions.Logging NuGet package, although it appeared ...

When trying to get the logging to Elasticsearch from .NET to work in the production environment, I spent too much time configuring the logger. It was mostly due to missing and incorrect documentation.
