We CAN use the Major.Minor.Patch.Revision format as a product version, but that won't work with major upgrades. An example of this would be 1.2.3-alpha45 which would require a different version number than 1.2.3-alpha46. 2018-01-30T00:00:00Z /blog/2018/10/generating-api-clients-using-autorest https://patriksvensson.se/blog/2018/10/generating-api-clients-using-autorest This blog post looks at automatically generating an HTTP API client from a OpenAPI specification (formerly swagger) using AutoRest. 2018-10-02T00:00:00Z /blog/2020/02/testing-stuff-with-windows-sandbox https://patriksvensson.se/blog/2020/02/testing-stuff-with-windows-sandbox Last week I decided that I wanted to try the new version of Windows Subsystem for Linux (conveniently named WSL 2). WSL 2 requires that the computer enrolls in Windows slow ring, and since the computer I was on didn't receive any insider builds at all, I went ahead and enabled the slow ring. The update started, and I went to bed. 2020-02-23T00:00:00Z /blog/2020/10/thank-you-octopus-deploy https://patriksvensson.se/blog/2020/10/thank-you-octopus-deploy When I started working on Cake in 2014, I did it to scratch an itch I had. FAKE existed (which has been a tremendous initial inspiration), but I didn't know F# enough (at all) to be confident enough to bet our build process on it. 2020-10-08T00:00:00Z /blog/2020/06/deploying-to-nuget-from-github-actions-using-cake-and-minver https://patriksvensson.se/blog/2020/06/deploying-to-nuget-from-github-actions-using-cake-and-minver I recently started moving some builds from TeamCity, Travis, and AppVeyor to GitHub actions, and while doing that, I thought I would also move to a more straightforward deployment process. 2020-06-22T00:00:00Z /blog/2016/12/azure-web-apps-and-the-certificate-store https://patriksvensson.se/blog/2016/12/azure-web-apps-and-the-certificate-store I was trying to load a certificate from the certificate store in an Azure Web App today, and for some reason I could not find it via it's thumbprint. Since I thought I was looking in the wrong certificate store, I went to Kudu to take a closer look via the PowerShell debug console. 2016-12-07T00:00:00Z /blog/2014/06/the-singleton-logger https://patriksvensson.se/blog/2014/06/the-singleton-logger It is widely accepted that you access logging frameworks via a static singleton instance, and most logging frameworks are designed to work like this. But why? Many people often refer to it as being a cross-cross cutting concern; and that it's therefore not important to do things by the book. Not only does most logging frameworks use the static singleton as a façade, but they also store process-wide state. 2014-06-18T00:00:00Z /blog/2014/07/its-not-a-party-without-cake https://patriksvensson.se/blog/2014/07/its-not-a-party-without-cake I have during my nine years as a (professional) programmer used several different build automation systems such as Rake, psake, CMake, TFS Build and FAKE, but none of these have allowed me to write my build scripts using C# - the language I use the most. 2014-07-18T00:00:00Z /blog/2019/09/how-to-find-a-nuget-package-path-from-msbuild https://patriksvensson.se/blog/2019/09/how-to-find-a-nuget-package-path-from-msbuild Lately I've been porting some projects at a client from .NET Framework to .NET Core, and as part of that I had to convert csproj files from the old project format to the new one. That means getting rid of package references in packages.config and replacing them with PackageReference elements in the project files. 2019-09-30T00:00:00Z /blog/2014/01/displaying-teamcity-build-status-on-github https://patriksvensson.se/blog/2014/01/displaying-teamcity-build-status-on-github Have you ever wanted to display the current CI build status for a TeamCity project in your GitHub README? I did but couldn't find any good, straight forward information about how to do it. Turns out it's quite simple. 2014-01-24T00:00:00Z /blog/2018/04/an-introduction-to-spectre-cli https://patriksvensson.se/blog/2018/04/an-introduction-to-spectre-cli I've been writing a lot of CLI apps, both at work and in my free time, and there's never really been a command line parsing framework that has fitted my needs. While being either too complex or too simple, it's always nagged me that I need to write so much code myself. What I wanted was a way to be declarative about my commands, options and arguments while still allowing composition of them. 2018-04-10T00:00:00Z /blog/2020/03/how-to-write-a-stateful-roslyn-analyzer https://patriksvensson.se/blog/2020/03/how-to-write-a-stateful-roslyn-analyzer I wrote a stateful Roslyn analyzer a couple of days ago to analyze the codebase at work for irregularities, and I thought I would share my findings on how I did it. 2020-03-07T00:00:00Z /blog/2019/12/roaming-profiles-with-windows-terminal https://patriksvensson.se/blog/2019/12/roaming-profiles-with-windows-terminal If you have more than one computer that you use, you might have noticed that it requires some work to keep your Windows Terminal profile up to date. 2019-12-02T00:00:00Z /blog/2014/11/cake-and-appveyor-integration https://patriksvensson.se/blog/2014/11/cake-and-appveyor-integration In this blog post I will show you how to use Cake with your AppVeyor CI builds. 2014-11-23T00:00:00Z /blog/2014/08/script-aliases https://patriksvensson.se/blog/2014/08/script-aliases Cake supports something called script aliases. Script aliases are convenience methods that are easily accessible directly from a Cake script. Every API method in Cake is implemented like this. 2014-08-19T00:00:00Z /blog/2019/03/build-counters-in-azure-devops https://patriksvensson.se/blog/2019/03/build-counters-in-azure-devops We recently migrated some builds from TeamCity to Azure DevOps at my client, and couldn't find a feature analog to TeamCity's %build.counter% which we've been using to get automatically incremented version numbers for artifacts. 2019-03-13T00:00:00Z /blog/2021/12/intellisense-for-your-github-action-workflows https://patriksvensson.se/blog/2021/12/intellisense-for-your-github-action-workflows Although I'm a big fan of GitHub, I'm not a big fan of YAML. When it comes to orchestrating my builds, I usually prefer some kind of build script, but bootstrapping that build script is a necessary evil so we're stuck with YAML for that part. 2021-12-22T00:00:00Z /blog/2023/11/building-an-iterator-in-swift https://patriksvensson.se/blog/2023/11/building-an-iterator-in-swift As part of learning Swift, I decided to port my project Spectre.Console (written in C#) to Swift. 2023-11-13T00:00:00Z /blog/2017/08/never-mutate-state-in-a-debug-assert-call https://patriksvensson.se/blog/2017/08/never-mutate-state-in-a-debug-assert-call Yesterday I encountered a bug in a library I'm working on that only seemed to occur when compiled in release mode. 2017-08-02T00:00:00Z /blog/2013/12/binarywriter-and-cplusplus https://patriksvensson.se/blog/2013/12/binarywriter-and-cplusplus A while back I had to read string data written by .NET's BinaryWriter in C++. I was initially a little bit confused about how the data was written but after using Reflector it turned out that the write method prefixes the string with a 7-bit encoded integer. 2013-12-16T00:00:00Z /blog/2014/04/introducing-lunt https://patriksvensson.se/blog/2014/04/introducing-lunt Last summer, a friend and I started to write a little Paradroid clone. Since my only real experience as a game programmer was with XNA and MonoGame, I had grown fond of the XNA Content Pipeline, and naturally wanted something similar for this project. 2014-04-05T00:00:00Z /blog/2017/12/conditionals-in-xaml https://patriksvensson.se/blog/2017/12/conditionals-in-xaml Ever wanted to display things conditionally in XAML based on a pre-processor directive like `DEBUG`? 2017-12-03T00:00:00Z /blog/2017/11/using-embedded-resources-in-xunit-tests https://patriksvensson.se/blog/2017/11/using-embedded-resources-in-xunit-tests I was reading Andrew Lock's excellent blog post about Creating parameterised tests in xUnit when I remembered something I wrote a while back that has proven to be quite useful. 2017-11-11T00:00:00Z /blog/2013/08/how-to-dynamically-add-attributes-to-a-class-with-castle-core https://patriksvensson.se/blog/2013/08/how-to-dynamically-add-attributes-to-a-class-with-castle-core Yesterday I was working on some unit tests that ensured that some user derived classes passed to a method were decorated with a specific attribute. 2013-08-15T00:00:00Z /blog/2017/12/binding-to-a-richtextbox-in-wpf https://patriksvensson.se/blog/2017/12/binding-to-a-richtextbox-in-wpf I've been doing some WPF development the last couple of weeks, and one thing that bugged me was that there is no way (as far as I know) to bind content to a RichTextBox. This makes it kind of difficult to follow the MVVM pattern since the view model needs intimate knowledge of the view. 2017-12-11T00:00:00Z /blog/2025/07/introducing-open-cli https://patriksvensson.se/blog/2025/07/introducing-open-cli About three years ago, I was invited to meetings with the System.CommandLine team at Microsoft. They were in the process of finalizing System.CommandLine and wanted input from people in the community, and I was included due to my work on Spectre.Console and Spectre.Console.Cli. 2025-07-07T00:00:00Z /blog/2013/08/culture-agnostic-string-comparisons https://patriksvensson.se/blog/2013/08/culture-agnostic-string-comparisons Something I've seen a lot at different clients is naive string comparison. The most common case is to do something involving String.ToLower() on both strings that are being compared and then an equality comparison of the result. 2013-08-22T00:00:00Z /blog/2020/05/targeting-arm-for-windows-in-rust https://patriksvensson.se/blog/2020/05/targeting-arm-for-windows-in-rust I wanted to run a thing I'm building with Rust on my Surface Pro X which is an ARM64 device the other day. My initial thought when I got the idea, was "I hope it's not complicated to do". 2020-05-26T00:00:00Z /blog/2020/06/enumerating-monitors-in-rust-using-win32-api https://patriksvensson.se/blog/2020/06/enumerating-monitors-in-rust-using-win32-api I had to enumerate all monitors yesterday using the EnumDisplayMonitors Win32 function, and I thought I would write a couple of lines about what I did since I couldn't find any useful information about how to do this. 2020-06-08T00:00:00Z /blog/2018/02/debugging-rust-on-windows-using-vscode https://patriksvensson.se/blog/2018/02/debugging-rust-on-windows-using-vscode I recently wanted to debug a Rust program on Windows that I had written, and was struggling with how to get it to work. Since there was quite a lot of hoops to jump through to get it to work, I though I should share it with other people as well. I've written this blog post from memory and I'm far from an expert in LLVM or Rust, so if you see something strange here then let me know. 2018-02-01T00:00:00Z /blog/2019/06/debugging-an-uwp-store-app-with-windbg https://patriksvensson.se/blog/2019/06/debugging-an-uwp-store-app-with-windbg I was encountering a rather irritating bug a couple of days ago that only manifested itself when built via the native toolchain in release mode. I couldn't get it to manifest itself when running from Visual Studio for some reason and the problem occurred so early in the app's lifecycle that I didn't have time to create a minidump of the process. 2019-06-27T00:00:00Z /blog/2020/03/creating-release-artifacts-with-github-actions https://patriksvensson.se/blog/2020/03/creating-release-artifacts-with-github-actions In this blog post, we'll create a GitHub Action that triggers each time a release is published, builds a binary on three different build agents (Windows, macOS, and Ubuntu), and attaches the compressed artifacts to the release. 2020-03-22T00:00:00Z
