CRUD with Blazor in .NET 8 🔥 Video & Code Inside 🚀


Hey Reader,

This week we're diving deep into Blazor via .NET 8, focusing on mastering CRUD operations using the fresh render modes—Auto, Server, WebAssembly, and even no render mode for static server-side rendering via stream rendering. Yep, that's a mouthful of new capabilities for you!

CRUD with Blazor in .NET 8 Video 🔥

No sweat, I've got you sorted. This week's video walks you through each render mode and demonstrates how to flawlessly execute CRUD operations, complete with persistence via Entity Framework and SQL Server Express.

Key Code Snippets 🖥️

If you're more of a code-first person, here's a sneak peek at the essential code sections. With the latest Blazor Web App template in Visual Studio 2022 Preview, selecting Auto or WebAssembly render modes gifts you two projects—Server and Client. The Server project comes fully equipped for Web API tasks, including the ability to add API controllers, which is vital for using server-side services in your client project.

Say you've crafted a simple game library entity:

Along with the requisite Entity Framework boilerplate:

Watch Your Steps!

Have you set all this up in the Server project? Ah, but what if you need to access your Game Entity or services from the Client project? To solve this, I shifted everything to a separate Class Library:

You'll notice that this setup closely resembles the older Blazor WebAssembly ASP.NET Core Hosted template from .NET 7.

The Nitty-Gritty

To call server logic from your client app, web service calls are still the way to go. Dependency Injection comes to the rescue, allowing us to implement the IGameService interface differently for the client:

Remember to register your GameService and HttpClient on both client and server ends.

Client:

Server:

And, of course, don't forget the new controller on the server:

I get it; this might feel overwhelming at first. But trust me, once you get your bearings, the new .NET 8 features will feel like second nature. I'm also working on a video that compares the .NET 7 and .NET 8 versions of a Blazor WebAssembly app. So stay tuned!

Hey friend, I just released a new video showing a better way to use GitHub Copilot in real .NET projects. Watch it here 👇 If you ever felt like Copilot starts strong but then your code slowly turns into chaos, you’re not alone. It happens to most developers when they start using AI without giving it the right guidance. In the video, I show you one simple file you can add to your project that keeps your code clean, structured, and consistent. No guessing. No random patterns. Just a clear...

Hey friend, I just published a new video that walks you through how to upgrade to .NET 10. Watch it here 👇 If you're already trying the update, you may have seen this: the app builds no errors but… Blazor doesn't load That happened in my project too. And the fix is small, but easy to miss. In the video, I show: how to update the target frameworks how to update NuGet packages what changed for Blazor and how to fix the missing static assets issue No hype. Just a clear step-by-step walkthrough....

Hey friend, I just released a new video that shows how to add AI to a .NET app. Watch it here 👇 In the video, I take a simple .NET project and make it smart with AI. The app can generate item backstories with one click. Like magic. No big setup. No overthinking. Just .NET, Copilot, and the OpenAI API working together. If you’ve ever wondered: How do I call the OpenAI API from a .NET app? Can Copilot help with real features? How do I make my app do more than CRUD? This will help. Give it a...
