I agree. Nothing beats using a well known framework for speed.
I think we also need to consider how much experience one has with a language. Most can pickup a new language relatively quickly, but it's not the same as having real experience with it.
At work, someone just started a new micro service written in Rust because they were familiar with Rust and thought they would be able to do something "fast". They spent at least half the time struggling with even basic dependencies, how to deploy it, monitor it and make it deployable. If this was a startup, they would have burned a significant amount of time that could have been spent on PMF
I don't want to fight you, because I don't know .Net well enough to have an opinion.
But I just want to say that I have the same feel when I develop using Spring Boot. I am extremely productive and seldom have to pull dependencies outside Spring for 80% of what I make.
