As a kid, I was fascinated by the possibilities of table top role playing games like Dungeons & Dragons, Shadowrun, and Mechwarrior, but rarely got to play them, aside from some combat encounters my brother and I set up and executed. Fast forward a few decades and I'm building software and AI solutions professionally with Leading EDJE, and one of my coworkers decided to start a RPG night. I was hooked immediately at the idea of playing a character, exploring a game world and a game master's story, and exploring the mechanics of a game system with characters and a…

Adding Revision Support to Entities in Entity Framework Core

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, efcore, engineering, entityframeworkcore, inclusive, software

Introduction As applications evolve, the need to track historical data or version control often arises. In this article, we’ll refactor an existing entity to support revisions using Entity Framework Core, allowing us to maintain a history of changes without duplicating the data model or introducing unnecessary complexity. We’ll walk through a step-by-step approach to transition a simple Document entity into a revisioned model. This method uses a discriminator to track multiple versions of the same document, with all revisions stored in the same database table. This approach is both flexible and scalable, making it easy to apply to other entities…

Blazor’s Authorization

stp2y0 CommentsNewsblazor, coding, community, development, dotnet, dotnetcore, engineering, firebase, inclusive, software

Disclaimer: based on my observation, not readings. Recently, I had to implement Firebase authentication for a Blazor WASM project. To my surprise, I discovered there's no ready-made authentication library for Firebase on .NET. While I found the Firebase Admin library, it wasn't quite what I needed for client-side authentication. So, I ended up building my own solution for .NET. Fortunately, I didn't have to start from scratch. Firebase provides a JavaScript SDK for authentication, which is quite straightforward to use and integrates well with Blazor WASM. Blazor handles authorization through a class derived from AuthenticationStateProvider. This class requires you to…

Converting Blazor Project to WebForms Core

stp2y0 CommentsNewsbackend, blazor, coding, community, development, dotnet, engineering, inclusive, opensource, software

WebForms Core technology helps developers manage HTML tags on the server side without the need for client-side scripting. WebForms Core is a feature in the core of the CodeBehind framework. Note: CodeBehind framework is a powerful replacement for ASP.NET Core MVC and Razor Pages and other backend frameworks.The use of WebForms Core technology also makes developers not need to use front-end frameworks such as Vue, Angular and React.However, these two are not a replacement for WebAssembly; But they are well coordinated with WebAssembly. The following project is the default version 8 of Blazor .NET Core technology, which has been rewritten…

My Experience with GitHub Copilot

stp2y0 CommentsNewscoding, community, development, dotnet, engineering, githubcopilot, inclusive, python, software, webdev

Hello,I'm Duke and I recently dove into using GitHub Copilot, and I’ve got to say, it’s been quite an adventure! I integrated it with a couple of languages—Python and .NET—and tried it out on several popular IDEs, including VSCode, Visual Studio, Rider, and PyCharm. Here’s a rundown of what I found during my experiments. Setting It UpGetting GitHub Copilot up and running wasn’t too tricky. However, if you’re using Visual Studio, make sure you’re on version 17.10 or later (2022). It’s a little bit of a hurdle if you're on an older version, but once you get through that, you’re…

Conditional application of chained LINQ queries

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, engineering, inclusive, programming, software

I write C# and I'm a big fan of using LINQ to create nice, readable chains of operations to filter and transform data in a functional style. int HighestEvenNumber(IEnumerable<int> numbers) => numbers .Where(x => x % 2 == 0) .OrderByDescending(x => x) .FirstOrDefault(); Enter fullscreen mode Exit fullscreen mode Sometimes though, there are conditions where parts of the chain should be included or omitted, but breaking the chain to add an if-statement feels wrong and disruptive. Let's say our previous example should throw an exception if there are no even numbers in the sequence instead of returning the default int…
