🤖 Can GitHub Copilot really build .NET & Blazor apps?

Published about 2 months ago • 1 min read

Hey Reader,

Last week, I tested GPT-5 Agent Mode on .NET and Blazor apps, and the results were surprising.

This week, I went a step further. I used GitHub Copilot inside Visual Studio and asked it to create real .NET and Blazor projects for me.

Here’s what happened:

  • Copilot generated a working calculator app in C#.
  • It built a Web API that responded with “Hello GPT-5 Agents.”
  • It even created a Blazor app with extra features like a reset button, a plus five counter, and a weather API.

Were there errors? Yes. Strange commands, failed builds, and confusing reloads all showed up. But in the end, we got working applications and some important lessons on why knowing your foundations is still crucial when using AI tools.

👉 Watch the full experiment here:

I am also working on a new .NET and AI course. In it, I’ll show you how to:

  • Use GPT in chat mode to generate code
  • Move on to agent mode to let it modify projects directly
  • And finally, use Copilot inside Visual Studio to build .NET and Blazor apps faster

You can join the waiting list here and be the first to know when it launches (and get a special launch discount).

I would love to hear from you: Would you trust Copilot or GPT-5 to build your apps, or do you think it is still too risky? Hit reply or join the comment section of the video and let me know your thoughts.

Take care,

Patrick

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...

Hey Reader, I just published a new video where I put GPT-5’s Agent Mode to the test. 🚀 Instead of asking it for something simple, I went all in: A .NET 9 console app calculator A Web API with endpoints and docs A Blazor Server app with extra counter buttons And even a Blazor app that calls a public weather API 🎥 Watch it now: In the video, I didn’t just type “make me an app” and hope for the best. I gave GPT-5 very specific prompts, like: “Please create a .NET 9 console application that works...

Hey Reader, I’m back! 🎉 I’ve been on parental leave for the past 2 months, enjoying time with the family. Now I’m diving back into videos and here’s the first one! 🎥 Watch it now: Here’s the TL;DR if you can’t click right now: AI can already write code, fix bugs, and explain complex concepts. So… are we doomed? No. AI isn’t replacing developers anytime soon. But: Developers who use AI will replace those who don’t. The best devs are using GPT to: Skip repetitive work Prototype faster Learn...
