It is weird now that you mention it. I worked in C# and .NET for a long time. In theory for 20 years. In practice I wasn't writing much C# after 2019 even though the team I led still used it.

I guess I... just got bored of it, and fed up of Microsoft. I came to hate Windows and having to work on Windows so much that it sort of tainted C# for me. I'm not saying I'd never use it again but, whilst it will run cross-platform nowadays, so will loads of other languages and frameworks, so it's never at the top of the list when it comes to choosing something for a new project.

As for TypeScript? Absolutely loathe it. I'll use it professionally when I have to, but I'd never use it for one of my own projects. It's just so ugly I don't even like looking at it. I get why people like it but, for me, it's not enough. If I'm staring at something all day then, I'm sorry, it can't be ugly.

But, strangely, I still use and enjoy VS Code from Microsoft, and have no plans to switch to anything else.

(I also still have an Office subscription - or whatever it is Microsoft are calling that suite nowadays, I don't care - because I still use both Excel and Word fairly frequently. I could probably get by without, but I actually quite like Office - even on the Mac.)

Did anyone ever explain why C# was not considered in the first place ?

Speaking of PostgreSQL and Microsoft, I was at at a presentation earlier this year and they are developing an underlying storage engine for it based on Azure Blob storage to get “instant” WAL replay across many replicas at once.

It was pretty impressive work to scale PostgreSQL.

TypeScript has fewer competitors for the frontend than C# does for the backend
