Podman Desktop–The WSL import of guest OS failed: exit status 0xffffffff

T o avoid carrying around multiple laptops for different customers I typically ask if they can provide me a VDI (for example through Azure Virtual Desktop). One of my clients is not on a cloud platform (yet), so the VM they provided me was running on a local(read: in a traditional datacenter) hyper-v cluster. As we were investigating to move to a container based development model, I installed Podman Desktop on the provided machine. Podman Desktop requires a Podman machine to be created to be able to run workloads. However when I tried to create a new machine, it failed with the following error message: Error: the WSL import of guest OS failed: exit status 0xffffffff I did a second attempt through the commandline but this failed as well: podman machine init Extracting compressed file: podman-machine-default-amd64: done Importing operating system into WSL (this may take a few minutes on a new WSL install)... WSL2 is not supported with your current machine configuration. Pl

GraphQL–Application Insights integration for HotChocolate 13

If you are a regular reader of my blog, you've certainly seen my earlier post on how to integrate Application Insights telemetry in your HotChocolate based GraphQL backend. IMPORTANT: Although the code below will still work, I would recommend to switch to the integrated OpenTelemetry functionality and send the information to Application Insights in this way. Today I had to upgrade an application to HotChocolate 13 and (again) I noticed that the application no longer compiled. So for people who are using the ApplicationInsightsDiagnosticsListener I shared, here is an updated version that works for HotChocolate 13: As I wanted to track the full operation I have overwritten the ExecuteRequest method, however if you only want to log any exception, I would recommend to override the RequestError and ResolverError methods: More information HotChocolate OpenTelemetry ( GraphQL HotChocolate 11 - Updated Application Insights monitoring (bartwullem

Azure Application Insights–Collect Performance Counters data - Part II

About 2 years ago I blogged about the possibility to collect performance counter data as part of your Application Insights telemetry. If you missed the original post, first have a quick read here and then come back. Back? As mentioned in the original post, to be able to collect this performance data, the Application Pool user needs to be added to both the Performance Monitor Users and Performance Log Users group. Although I updated our internal wiki to emphasize this, I still noticed that most developers forget to do this with no collected data as a result. (Who reads documentation anyway?) So let’s do what any developers does in this case, let’s automate the problem away… I created a small tool that can be executed on the IIS web server. It goes through all the application pools, extracts the corresponding user and add it to the 2 groups as mentioned above. I think the code is quite self-explanatory. Here is the part where I read out the application pools: And here I ad

MassTransit–Change log level

A short post today; a colleague wanted to investigate a production issue when sending and receiving messages using MassTransit. He couldn’t find immediately how to change to capture more details about the MassTransit internals. I had a look together with him. So for further reference you can find the answer here. Using Serilog On this specific project he was using Serilog so let me first show you how to change the log level for MassTransit when using Serilog: Using Microsoft.Extensions.Logging And here is the code changes required when using the default Microsoft.Extensions.Logging: Remark: I would certainly recommend to have a look at the observability features of MassTransit as well and look to implement OpenTelemetry in your application.

ImageSharp–Image.Load() Compiler error after updating

On one of my pet projects I’m using ImageSharp to manipulate images. It is a great library that comes with a lot of features in it. And performance and memory usage is good which is quite important when manipulating images.  Remark: Be aware that a commercial license is needed in some conditions. So check out the pricing page before adding this library to your application. I decided to add some new stuff but before I did that I updated the library to the latest version. However after doing that my original code no longer compiled. Let’s see how we can fix this… Here is the original code: This specific overload no longer exists in the latest version. So I started to update my code to a supported overload: Remark: Notice that I also switched to an async overload but know that a synchronous version exists as well. However by doing that I no longer had the format information available. The good news is that this information could now be accessed through the image.Metadata

Code & Comedy 2024–This session will give you 2.6 hours of your time back

Yesterday I had the pleasure to present at Code & Comedy 2024 . Again it was a great combination of inspiring sessions, great food and a lot of nice people to meet. All of this followed by a Comedy Act by Jan Jaap van der Wal. I never thought that AI could be that much fun! Note to myself: Next time make sure that I’m not one of the 2 Flemish guys in the room. I did a presentation titled " This session will give you 2,6h a day of your time back!"; which is a hard promise to make, so I hope that the participants could confirm if I succeeded or not. In the session I shared some surprising insights in behavioral science and explained how we can apply this knowledge in building AI assistants. In case you missed my session or you want to a look at the code in more detail, here are the relevant links: Presentation: wullemsb/presentations: Repo with all my (public) presentations ( Source code: wullemsb/SemanticKernel: Demo code for my AI session (githu

Github Copilot extension disabled after upgrading to Visual Studio 17.10.2

After upgrading my Visual Studio to 17.10.2, I got a warning that my Github Copilot and Github Copilot Chat extensions are incompatible with my Visual Studio version and will be disabled. The following extensions are disabled because the installed version if not compatible with Visual Studio Pro 17.10.34505.107. - GitHub Copilot - GitHub Copilot Chat I started to get a small panic because once you are used to have a Copilot assistant you never want to go back. So after my Visual Studio was up and running, I opened the extension window and indeed both extensions were disabled: I first tried to reinstall the extension but I got the same incompatibility message. Does this mean that I can no longer use Copilot? Luckily the answer is no.  Starting from Visual Studio 17.10.2 Github Copilot and Copilot Chat are no longer separate extensions but became part of Visual Studio. So although the extensions are no longer there, Copilot (Chat) was still available as I found out. A bette
