Posted on December 31, 2023
It has been a while since I wrote those Puppeteer-Sharp blog posts (maybe it’s time to do it again?). However, I thought it would be nice to recap all the progress made in 2023. It can be quite challenging to keep Puppeteer-Sharp up-to-date. On one side I was implementing great...

Puppeteer-Sharp 3 is here!
Posted on March 22, 2021
I’m so excited to announce that, after eight months, Puppeteer-Sharp 3 is here! Getting Puppeteer-Sharp 3 out was quite a challenge. The lack of sponsors on Puppeteer-Sharp and the strong support of Microsoft on Playwright-Sharp made me put all my efforts on Playwright-Sharp in the past few months. But while...

Implementing interprocess communications between .NET and Node.JS
Posted on June 8, 2020
Introduction If you want to implement interprocess communication, you will end up reading about pipes and file descriptors. The problem I found is that .NET does a great job hiding all these concepts from us. I don’t know about you, but I didn’t even know much about these concepts until...

In other words, Playwright-Sharp extensions. We shipped v0.10.3 of...

Automating Microsoft Edge with Puppeteer-Sharp
Posted on April 22, 2019
As you may have heard, Microsoft made available to the public its Chromium-powered Edge browser. Maybe this question won’t qualify as technical interview question but: If Puppeteer-Sharp automates Chromium, and Microsoft Edge (insider) is powered by chromium, that would mean that… When you call Puppeteer.LaunchAsync, one of the values you...

Getting ready for Puppeteer-Sharp Firefox
Posted on March 11, 2019
You might not know, but Puppeteer’s team is making good progress on a Puppeteer version for Firefox. That’s a big deal. If we have trouble sometimes trying to get a site look the same in all browsers, imagine trying to use the same debugging protocol. They even had to fork...

Posted on February 11, 2019
We didn’t get a (Google’s) Puppeteer release last month, but that doesn’t mean that we didn’t make good progress on Puppeteer-Sharp. We were working a lot on tech debt. We tried to make our builds more reliable. Many builds tend to fail due to timeouts or race conditions, so we...

Pro Asynchronous Programming with .NET by Richard Blewett and Andrew Clymer was the third book on my list. About the book This book has some great explanations about the async internals in .NET. The problem I’ve found is that, maybe because it’s a book from 2013, it puts lots of...

Going deeper with async programming
Posted on December 17, 2018
When you start coding async apps in C# it looks super simple, almost magical. You put some asyncs here some awaits there, and you are done! But then, you start using asyncs more and more, and problems arise. As you don’t know how this new technology works, you start adopting...

Last report of 2018! No, I won’t get emotional. Let’s go to the facts (cries a little bit thinking about December). We launched v1.10 during November. Every time I say “and we caught Puppeteer” they release a new version at the very next day, so I won’t say that. But...

How do you spell 👹 in C#?

C# wishlist - Internal interfaces
