CRUD with Blazor SSR (Static Server-Side Rendering) 🚀, C# Tip: Null-Coalescing Assignment Operator 🌟


Hey Reader,

This week, I've got a new video for you about Blazor SSR. It's all about using static server-side rendering in Blazor without needing things like websockets or WebAssembly. It's a complete guide on creating, reading, updating, and deleting data. Plus, I've added a bonus tip about a neat feature in C# to make your code look better and easier to understand. Hope you enjoy it!

🚀 Learn CRUD with Blazor SSR in .NET 8

Check out this one-hour video where I dive into Blazor and .NET 8. You'll learn how to handle data - adding, viewing, changing, and removing it - using Blazor's static server-side rendering method.

🌟 Quick C# Tip: The Null-Coalescing Assignment Operator

When you're working with data in Blazor SSR, the ??= operator in C# can be really useful. It helps you set a value to something only if that thing doesn't already have a value. It's a simple way to check if something is empty and fill it if it is. Here's a quick look at how it works and why it's great for making your code cleaner and easier to read.

Let's look at how this operator works in practice. The basic syntax is as follows:

This translates to two scenarios:

  1. If variable is not null, the code does nothing.
  2. If variable is null, it gets assigned the value.

Examples

To appreciate the elegance of this operator, let's compare two code snippets.

Traditional Approach (Without ??=):

Using the Null Coalescing Assignment Operator:

Notice how the latter approach reduces the code complexity and enhances clarity.

Why Use It?

  • Cleaner Code: It significantly cuts down on the repetitive code often seen in null checks.
  • Enhanced Readability: The operator's purpose is instantly clear, reducing clutter in your code.
  • Efficiency Boost: Beyond just being a neat shorthand, it can also enhance performance in certain cases.

Whether you are a beginner or an experienced C# developer, the ??= operator is an invaluable addition to your coding toolkit.

Consider a scenario where you need to initialize a complex object but only if it hasn't been set up yet. The ??= operator makes this task straightforward, ensuring your code remains clean and readable.

While this operator is powerful, it's crucial to use it wisely, though. Always prioritize clarity in your code over mere brevity.

Have you tried using this operator in your code? How did it go? Let me know!

Hey Reader, .NET 10 is almost here, and it brings a big upgrade for validation in Minimal APIs. In this week’s tutorial, I’ll walk you through how validation works now in .NET 10 (using Entity Framework, Scalar, and Minimal APIs). Before, writing validation logic in each endpoint was a pain. You had to manually check for null values, invalid quantities, or missing fields. But in .NET 10, that’s all built-in and super clean. Watch the full tutorial now: 👇 Happy coding! Take care, Patrick

Hey Reader, If you’ve been coding for a while, you’ve probably asked yourself this too: “Am I getting better… or just older?” I’ve been writing software for fifteen years now, and that question still sneaks up on me. But looking back, I’ve realized something: real growth in tech isn’t about frameworks or chasing trends. It’s about staying curious, patient, and keeping your spark alive when everything feels heavy. So I made a new video about it, my 15 biggest lessons from 15 years of coding....

Hey Reader, If you’re a Blazor developer, you know that annoying flash when your app loads data during pre-rendering. It’s been around forever. Sure, you could disable pre-rendering, but then you'd hurt performance and SEO. Well… with .NET 10, we finally have a real fix: the new Persistent State Attribute. 🎉 🎥 Watch my full tutorial about it here: In this video, I walk you through: ✅ What causes the flashing issue ✅ Why disabling pre-rendering isn’t ideal ✅ How the new Persistent State...
