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!
