This new version brings real virtualization using a real linux kernel, but, compared to a traditional virtual machine, it runs on a lightweight hypervisor getting close to bare-metal performance.

This will also be used by Docker under the hood, boosting the start-up time and general performance of our containers. Sweet! Furthermore, with WSL2, VPN connections automatically propagate to linux correctly, which is great news when working from home.

So let's stop talking and get to update our Ubuntu 18.04 WSL environment to Ubuntu 20.04 running on WSL2.

Logs are a key element for diagnosing, monitoring or auditing the application's behaviour, so if you are either a library author or you are developing an application, it is important to ensure that the right logs are generated.

Would it be nice if there was an easy solution to write tests for it? Let's start a journey through the best approaches to tests logs when using Microsoft.Extensions.Logging.

I often get asked if it is better to have a global.json in a .NET project (not necessarily .NET Core) to define a specific .NET Core SDK version and, unfortunately, if you need a short answer you will get from me the typical engineer answer: it depends! Here is the full answer so you can decide what suits best for your needs.

HttpClientLab turns the HttpClientFactory into a lab, so you can mock the HttpClient to write tests.

Recently I had to install Python 3.4 on the Raspberry Pi, which is not part of the current distribution as it is based on Debian Wheezy which includes Python 3.2.3.

The following steps allow you to install Python 3.4 with pip and sqlite support, without messing with your other Python versions.
