This is a small introduction post about the Generic Hosting Environment in ASP.NET Core 3.0. During ...

New in ASP.NET Core 3.0 - Blazor Client Side

With this, it is ...

MVP for four times in a row

Another year later, again it was the July 1st and I got the email from the Global MVP Administrator I'm waiting for :-) Yes, this is kind of a yearly series of posts.

Self-publishing a book

While writing on the Customizing ASP.NET Core series, a reader asked me to bundle all the posts into a book. I was thinking about it for a while. Also because I tried to write a book in the past together with a collogue at the YOO. But publishing a book with a publisher in behind turned out to be stress. Since we have a family with small kids and a job where we work on different projects, the ...

On my Twitch stream I planned to show how to migrate a legacy ASP.NET application to ASP.NET Core, to start a completely new ASP.NET Core project and to show some news about the .NET Developer Community.

Implement Middlewares using Endpoint Routing in ASP.NET Core 3.0

If you have a Middleware that needs to work on a specific path, you should implement it by mapping it to a route in ASP.NET Core 3.0, instead of just checking the path names. This post doesn't handle regular Middlewares, which need to work all request, or all requests inside a Map or MapWhen branch.

Git Flow - About, installing and using

The people who know me, also know that I'm a huge fan of consoles and CLIs. I run the dotnet CLI as well as the Angular CLI and the create-react CLI. Yeoman is also a tool I like. I own a Mac, but cannot really work with the Mac UI. I really prefer the terminal in Mac. Also Git is used in the console the most time. The only situation where I don't use git in the console, is while resolving merge ...

Thoughts about repositories and ORMs or why we love rocket science!
