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...

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...

Hey Reader, You may have seen the recent blog post from Jimmy Bogard (creator of MediatR and AutoMapper) announcing that these libraries are going commercial. And to be clear, I fully support that. Time is money, and supporting your family always comes first. BUT… In most of my projects, I don’t actually use everything MediatR offers. I usually just need a small part of it, the classic "send a request, get a response" pattern. So I thought: why not build a simple version myself? 👉 That’s...
