A new installation of Windows 11, a new challenge to overcome. This time the installation started without a problem, but later on it could not find any internet connection. Neither the ethernet cable nor the wireless network worked because Windows did not install any drivers for the network adapters.
After updating the SonarQube tasks in our Azure DevOps pipeline, we got this error message:
java.lang.UnsupportedClassVersionError: org/sonarsource/scanner/cli/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 57.0
When we run our ASP.NET application from the command line, we see that it only starts the HTTP port:

Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Development info: Microsoft.Hosting.Lifetime[0] Content root path: C:\Users\jg\source\repos\WebApplication1\WebApplication1
Many tasks for Octopus Deploy in Azure DevOps work asynchronously. What is great in fire-and-forget scenarios, can be a problem when we need to finish a task before we go to the next one.
We had many failing BDD tests right at the beginning of the test run. After a long and cumbersome debugging session, we found the source of the problem: Our tests started before Octopus deployed our release to the server. But how can we delay our pipeline enough until Octopus finishes its work?
For the last few weeks, I got this annoying behaviour in the Windows task manager: When I started it and went to the performance tab, it showed the current system load and then it stops. The screen freezes and the values are no longer updated.
I had a query where I had to find the larger of two values. The MAX() function may sound like the thing you could use, but that function only works with aggregates and GROUP BY. I had to search for an alternative and found the IIF function.
When it comes to testing, we usually hear that the tests are too slow. While that is a problem, we can also run into unexpected problems if the tests run too fast.
We had this line in one of our tests that checks with Fluent Assertions that the newest entry for our order history was written in the last minute:
Hangfire is a great tool to for background processing in .Net. We use it for all our projects, and it works without any problems.
There is only one bit of nitpicking we found: If you use Hangfire with multiple projects, it is a bit hard to keep the dashboards apart. By default, the tile reads "Hangfire Dashboard" in all of them:
When we start a new project, we best create a Git repository right away. The only problem when we do that from the command line is that we do not get a .gitignore file. Without such a file, Git will track all files in our repository – including *.exe, *.dll, *.pdp and many more that we do not want. We could go and find a .gitignore from a different project. But there is a better way for our .Net projects:
On a regular Linux, we would use this command to restart the computer:
