On Bluesky now. For #EFCore peeps: I'm not on the Entity Framework team anymore. I thought I would work on EF Core until I retired, and beyond. Very sadly, that turned out not to be possible. I'm going to really miss the team and the community. But on to new and exciting things!

I have recently discovered a library called #grats for building #graphql servers in type script. I liked it so much that we decided to put a cherry on the top 😂 Join me!
I did a Build 2024 session on #EFCore with @shayrojansky and @JamesKovacs. Good luck finding it by any organic means, so here's a link! youtube.com/watch?v=LuvdiU… Get the word out there! Good #EntityFramework content does exist, it can just be a bit hard to find!
I don't like it here anymore. So long, and thanks for all the fish.
Issues with @monzo: - The "confirming your identity" screen hangs - Support chat is not responding - Call to customer service was disconnected after 30 minutes without any answer. What's going on @monzo? Seriously considering changing banks at this point.
