Project mention: My new hobby: watching AI slowly drive Microsoft employees insane | news.ycombinator.com | 2025-05-21
Yes but the improvements are very gradual. It takes years for something to reach maturity. At least for the web stuff which is what I know of.
Eg:
Minimal APIs were released in 2021 but it won't be until .NET 10 that they will have validation. Amazing that validation was not a day one priority for an API. I'm not certain if even in .NET 10 Minimal APIs will have full parity of features with MVC.
Minification of static assets didn't come until .NET 9 released in 2024. This was already commonplace in the JS world a decade earlier. It could have been a quick win so long ago for .NET web apps.
Blazor was released in 2018. 7 years later they still haven't fixed plenty of circuit reconnection issues. They are working on it but progress is also quite slow. Supposedly with .NET 10 session state will be able to be persist etc but it remains to be seen.
OpenAPI is also hit and miss. Spec v3.1 released in 2021 is still not supported. Supposedly it will come with .NET 10.
Not from .NET but they have a project called Kiota for generating clients from OpenAPI specs. It's unusable because of this huge issue that makes all properties in a type nullable. It's been open since 2023. [1]
Etc.

Project mention: PeachPie Compiler: Compile and run PHP on top of .NET runtime | news.ycombinator.com | 2024-10-08
we have attempted to use it for that, but it was really hard and we ended up rewriting from scratch.
The activity graph on GitHub says it is mostly dead. There is some activity, but at best it is in maintenance mode. It used to be sponsored, but not anymore IIRC
