Your continuous integration script often looks like dotnet build mysolution.sln and dotnet test mysolution.sln. In my case, I have a solution that contains multiple class libraries and a few WPF projects. I want to create NuGet packages and also test projects on Windows, Linux, and Mac. However, you cannot build WPF projects on Linux or Mac. This means dotnet build fail on these platforms. One way to deal… [read more]

This website is hosted on a static website hosting provider and I use Cloudflare CDN to improve the performance. These 2 services allow me to host this website for free even if I got more and more visitors. However, I do not have lots of analytics. For instance, I want to know where the user comes from using the HTTP referer header or if they got a 404. Google Analytics is useful but most users use an… [read more]

In a project I had to create something similar to a syntax highlighter for a Blazor application. The code takes a string and highlights some parts of it. So, the idea is to create a component which outputs a raw html fragment that uses <span class="style-1">text</span> to colorize some parts of the string. Also, it should use CSS isolation as the style is specific to the component. I've already written… [read more]

Asynchronous methods have existed for a few years in the .NET ecosystem. Many methods know how to handle Task. For instance, Task.Run has overloads to handle tasks correctly: Task Task.Run(Func<Task> action) Task<TResult> Task.Run<TResult>(Func<Task<TResult>> action) // Task Task.Run(Func<Task>) // Wait for the inner task to complete await Task.Run(async () => { await Task.Delay(1000);… [read more]

If you want to rewrite the revision history of a git repository to remove secrets or useless big files, you may know the git filter-branch command. This command is hard to use and very slow. There are multiple alternatives to git filter-branch such as git-filter-repo or BFG Repo-Cleaner. But, as a .NET developer, I would like to use .NET to script the history rewrite. Download .NET:… [read more]

I needed to bind an <input type=number> in a Blazor application. I want to get the value as soon as the user changes the value. There is no problem for integer values. However, this is not as simple for decimal values. First attempt: <input type=number> First, I started with a basic solution. I use an input element and set the oninput event to bind the value as soon as the user change the value. <input… [read more]

If you are building a web application using ASP.NET Core (MVC, Pages, Blazor), you may rely on npm to minify and bundle your css and js files. This means that to build your application, you need to run an npm script such as npm run build before executing dotnet build. That's not convenient! What you want is only to build your application using dotnet build or from Visual Studio. .NET relies on MSBuild to… [read more]

Windows Subsystem for Linux (WSL) allows running one or multiple Linux distributions on Windows. Like any Operating System, you must install security updates on it. Instead of doing it manually, let's automate it using the Windows Scheduler! Open PowerShell and run the following commands to create a scheduled task that updates the default WSL distribution once a week. #… [read more]

It's common to use int, Guid, or string to represent entity ids because these types are well-supported by databases. The problems come when you have methods with multiple parameters of the same type. In this case, it's easy to mix up parameters when calling these methods. Issue GetIssue(int projectId, int issueId) { /* todo */ } int projectId = 1; int issueId = 1; Get(issueId, projectId); // wrong… [read more]

In a previous posts, I explained how to computing code coverage for a .NET Core project with Azure DevOps and Coverlet. In this post, the code coverage visualization could be done directly in Azure DevOps. As a developer, you want to see these results directly into the IDE. Download the code coverage file from the build artifacts Open the file in Visual Studio In the "Code Coverage Results" tool window,… [read more]
