Ask HN: Why do you think F# is not more popular, even within the .NET ecosystem?

My last experience with the language date from a couple.of years ago, overall it was kind pleasant : light wait syntax, goodish tooling and nice async programming support. Fast forward today, I wanted to explore asp.net and most of the example are in C# and the overall community/support for F# seems lower than say Scala or kotlin. What happened ?
